Checking hard drive for errors is not a major issue. There are some features which are provided by the operating system itself to do so. But then, what could be the reasons that you would like to go for checking a hard drive for errors. Let us first delve into these reasons, so that we know, when is the right time to go for error checking in a hard drive.

When to Check Hard Drive for Errors?

Data is the most important resource in any organization, or for a matter of fact, for any individual. When a hard drive fails, it takes a lot of your important data along with it. Try to understand the initial signs that may point the chances of a hard drive failure. Once, you recognize the errors, you will find out that it’s not that difficult to retain the health of your hard drive. However, it is not necessary that your hard drive will show you some problems before it fails. One day your hard disk is performing well and the very next day, your processor is not even able to read your hard drive. However, normally the hard drive starts with a handful of bad sectors, which keep on multiplying over a period of time. If you are astute in marking these problems and going for the troubleshooting part, then you can just get a hand on it and save the important data in your drive. Let us take a look at some of the important points, which straight away indicate that you should check your hard drive for errors.If your hard drive makes strange noises, then it is the right time to go for checking hard drive for errors.If your disk defragmentation program indicates that you should check your hard drive for bad sectors, then you should not even give it a second thought.If you are not able to access a particular portion of your hard drive (a particular file) or if one of your drives takes time in opening, then again, you should check the hard drive for speed.How to Check Hard Drive for Errors?

Anyone who has ever used DOS (Disk Operating System) of course must be acquainted with the chkdsk command. The command is still useful for most of the Windows operating systems. However, there are a lot more utilities that can be tried out. But first of all, let us try to understand how to go the old way for checking hard drive for errors. Find out more information on hard drive data recovery.

Check Hard Drive for Errors Using chkdsk
The chkdsk command can be used for sorting out a lot of hard drive problems. Some of them include lost cluster problems, cross linked files, directory errors and the most common – bad sectors problems. So, how can you use this command? You need to login into your computer as an administrator. Keep it in mind, this method is primarily useful for those who use the Windows operating system. Go to the DOS prompt, i.e. the command line. To do so, simply type, chkdsk <volume drive> on the command line. The amount of time, chkdsk takes to run will depend on the size of the drive and the number of files and folders in it.

So, what are the results that check disk shows. If it displays a 0, then it means that no errors were found. A 1 indicates that errors were found and resolved at the same time. 2 indicates that disk cleanup was performed. If /f was not specified then the disk cleanup may not have been performed. And if 3 is displayed, then it means that the errors could not be checked or fixed. Find out more information on how to check hard drive health.

One prompt step from your side, on the very first sight of hard drive problems, will help you save all your valuable data.

You have been using your computer hard disk for a while now, and it has started to show some problems. What do you think can be done?

Be it any kind of computer part, it is obvious that after using it for a while, it would tend to give some problems. So is true with computer hard drives which are the most essential means of data storage today. The problems that can arise out of hard drives can be as simple as an hard disk error on the computer screen or as serious as a strange sound coming from the device.

If there is a sound coming from the hard disk, you need to understand that it is a hardware problem which can only be diagnosed by a professional computer repair technician. On the other hand, if there is a hard disk related error popping up on your computer monitor, chances are that it is a problem of bad sectors. In such a situation, you need to fix bad sectors. Before moving on to how to recover bad sectors, let us first know in detail what are bad sectors.

What are Bad Sectors?

For getting a good understanding of bad sectors, you will have to first take a look at what are sectors. Technically, sectors, also known as blocks or clusters, are the smallest units on the hard disk in which the data is stored. A bad sector on the hard drive is created when that particular sector goes defunct. Bad sectors may be created because of using the hard disk for a considerable amount of time. It may even happen that a new hard disk has bad sectors by default.

Other reason for bad sectors on hard drive is physical damage. It is also believed that excessive heat in the computer cabinet leads to bad sector creation. If you do not check hard drive for errors with few bad sectors present; these bad units can multiply overtime. If a sector turns bad, the data that was stored on it is lost or gets corrupted. If your hard disk consists of a group of bad sectors, you may notice that its overall storage capacity of the disk has decreased.

How to Fix Bad Sectors on Hard Drive?

When we say repair or fix bad sectors, it generally means to set the bad sectors aside from the rest. The actual repairing of the bad sectors is not possible. For computer users who have Windows or Mac computer operating systems installed on their systems, the marking of bad sectors can be done using a default application. On a system with Windows OS; right click on the drive that you think has bad sectors, click on the ‘Properties’ option, select ‘Tools’, and finally click on the ‘Check Now’ option. A window will be displayed asking for confirmation of automatically fixing file system errors and scanning for and recovering bad sectors. You can then begin the process by clicking on the ‘Start’ option. On Mac OS; select Applications, then double click on the ‘Utility’ option, and find the ‘Disk Utility’ and start it. Now, the next step is to select the hard disk icon which is located on the left side of the application’s interface. Then, click on ‘First Aid’ and ‘Show details’ options on the interface. Clicking on ‘Verify Disk’ will start the operation of checking bad sectors.

Swapping hard drives between computers is a very good idea if you have purchased a new computer. Instead of simply discarding the old hard drive, you can use it in your new computer and this will give you a lot of benefits. You will end up having more storage space in your new computer, you will have a safe place to backup your current files and software, and you will also not run the risk of having your old files and data fall in the wrong hands.

Swapping hard drives between computers is not a difficult task, and you do not need to visit a computer repair shop to carry it out. Of course, if you have no idea what the inside of your machine looks like, and if you have absolutely no clue about how to connect a new hard drive, then you must visit an expert. But you can easily learn how to swap hard drives, and then you can carry out this task for yourself.

What are Hard Drives?
A hard drive is a component inside your computer that contains all your data. This is where all the information on your computer is stored. Every computer has a hard drive, and this is an absolutely essential component of desktop computers or laptop computers. It is very easy to swap hard drives in desktop computers as they are easily accessible and they can hold more than one hard drive at a time. Swapping hard drives between laptops is a bit more complicated, and this is further compounded by the fact that laptop computers can only hold one hard drive at a time.

So the answer to the question Can you swap hard drives? is a resounding yes, but the benefits of additional space and another source of back up can only be enjoyed in desktop computers. Swapping hard drives between computers is something that you should carry out only if you are absolutely certain that you will reap all the benefits of doing so. Hot swapping hard drives is possible, but only with external hard drives. It is not advisable to attempt this with your internal hard drives.

Swapping Hard Drives
When you get down to swapping hard drives between computers, you need to open up the old computer and locate the old hard drive. You need to keep two things in mind; firstly ensure that the power is switched off and all cables are disconnected, and secondly ensure that your old drive does not have computer viruses in it. If it does, then you need to make sure that your new computer has an official and up to date antivirus software active on it.

Carefully observe how the old hard drive is attached to the motherboard before you go ahead and remove it, because you will need to install it similarly in the new computer. The wires that connect the hard drive to the computer motherboard will be a ribbon data cable of sorts, and most old machines use a cable known as a PATA (Parallel ATA) cable. Newer machines make use of a SATA (Serial ATA) cable, and you must therefore attach your old hard drive to the secondary controller of the new motherboard. This will enable you to use the old hard drive. Refer to the manual of your motherboard for some changes that you may have to make in the BIOS settings. Read more about hard drive data recovery.

Now you must mount the old hard drive into the new computer and then attach the data cable. You can locate the data cable by following the cable that is attached to your optical drive (CD drive or DVD drive) and then finding another socket for the hard drive. Also attach a spare power cable into the hard drive. Once you have attached this cable, swapping hard drives between computers is successfully complete.

To check if you have successfully carried out the swapping, switch on your new machine and go to ‘My Computer’ and see if your old hard drive has been listed. If you see it listed, swapping hard drives between computers has been successful. Note that the operating system on the old hard drive will not affect the machine, as the computer will always look at the new hard drive first when it is booting up.

While formatting the hard drive into different volumes, one has two options to choose from when it comes to the kind of file system you want. One is NTFS (New Technology File System) and the other is FAT (File Allocation Table). If you haven’t given much thought as to which is the best file system to opt for, then you eventually will have to, when you know about the FAT32 file size limit! It decides how ‘fat’ a file you can store on a FAT32 formatted hard disk.

About FAT32
Before we talk about FAT32 file size limit, let us know something more about this file system. The FAT32 file management technology, along with its predecessors (FAT16 and FAT12) were developed by Microsoft. The FAT32 was developed in particular in 1996 and launched with the Windows 95 operating system.

Though FAT32 has been outperformed by more sophisticated and advanced file systems like NTFS, it is still the preferred file system for storage devices like flash memory cards, digital cameras, external hard drives and USB flash drives, as it is compatible with most disk operating systems, including Linux, Macintosh and Windows. The main reason for the ineptitude of FAT32 is the the simplistic data structure that it has, which makes every file operation very time consuming.

It allows for drive sizes of 8 Terabytes (240) with 32 Kebibyte (1024 bytes) clusters. Theoretically, a FAT volume cannot go beyond 137 GB in size as the FAT structure cannot grow beyond a maximum size of 222 clusters. This limitation was imposed because with greater volume sizes, data transfers becomes too slow under FAT32 format.

File Size Limit For FAT32
Most computer users (which included me, until very recently) are usually not aware of the fact that there is a maximum file size memory limit on every formatted hard drive. This file system’s maximum limiting size on stored files is set by its inherent design considerations. The FAT32 file size limit is only 4 GB minus 1 byte (232 – 1 bytes). That means, any kind of file cannot attain a maximum size of 4GB. Therefore, FAT32 is unsuitable as a file system for large databases and video applications.

Many people that use video converter software, find that creating video files greater than 4 GB is just not possible on a hard drive formatted using FAT32 format. Though initially, one may think that it is due to some flaw in the video converter software, the problem lies in the limitation of FAT32 file size limit itself. So, there is no option but to resort to an NTFS format for hard drive formatting when you have large sized files, greater than 4GB. The actual maximum volume size allowed under a FAT32 format is 2 terabytes. The maximum number of files that one can store under FAT32 is 268435437.

One way out of this constraint imposed by FAT32 file size limit is to split the file into two parts with sizes not exceeding 2 GB. The best option is to convert the file system from FAT32 to NTFS, by using the following command. Just open command prompt by going through ‘Start > Run’ and then type the following

C:> convert Drive Name: / fs : ntfs

Type the name of the drive in place of the drive name and your FAT32 drive will get converted to NTFS. With that, your problem will be solved as NTFS allows a maximum file size limit of 16 Terabytes!

Hope this article has clarified your confusion, if any, about the FAT32 file size limit.

Do you frequently get messages like ‘Cyclic Redundancy Error’ while retrieving data from your hard drive? Then you may be facing the problem of having bad sectors on your hard drive. It is a frequent problem caused in old and overused hard drives. In this article, I explain how to repair bad sectors on hard drives and save your data.

What are Bad Sectors on Hard Drives?

Before we talk about how to fix bad sectors on hard drive, let us understand what we mean by bad sectors. A computer hard drive is a magnetic storage disk on which data is stored by changing of its magnetization states. The disk is designed to function as a data bank with addresses for each region. It is divided into concentric tracks starting from the center, towards the outer rim. These tracks are further divided into sectors by radial division. Every sector is a unit data storage space which holds about 512 bytes of data. On a hard drive with a total memory capacity of 200 GB, there are as many as 400 million such sectors.

A bad sector on hard drive is a physically damaged sector which can no longer be accessed by the operating system. When this bad sector happens to be a region where you have stored data, you get the ‘cyclic redundancy error’ as the operating system cannot retrieve data from that region. To check for integrity of written data, parity checking bits are written while storing data on a hard drive. The data may not be read due to inconsistencies of parity checking bits that are verified while writing and reading data from a hard drive.

What Causes Bad Sectors on Hard Drives?

There are many reasons that can lead to a hard drive bad sector. The main reason for bad sectors is a loss of magnetism of the hard drive surface in certain areas with time. Bad sectors may also be caused by sudden physical shocks to the hard drive, sudden power shutdown and interruption of reading and writing operations on the disk. A failing read-write head of a hard disk is another cause of bad sectors getting created.

If the bad sectors are caused due to loss of magnetization, the damage is irreversible. However, if the problem is due to inconsistencies in parity checking bits, it can be corrected by using appropriate software that can rewrite and restore these bits.

How to Repair Bad Sectors on Hard Drive

Let us now see how to go about repairing bad sectors on hard drive. Taking into consideration that bad sectors will be eventually created over the usage life of the hard drive, manufacturers make a provision of unused spare sectors on the hard drive which can be utilized when bad sectors occur on a hard disk. When the disk controller encounters a bad sector, it remaps data to a different spare sector on a hard drive automatically. If you are using a windows operating system, there are two built-in programs that you can use to repair bad sectors on hard drive. One is the CHKDSK and a more advanced version of it called ‘ScanDisk’.

To locate bad sectors and remap data to other spare sectors, the CHKDSK or ScanDisk utility writes on and reads every region of a hard drive volume. Once a bad sector is detected, it is ensured that data is no longer written in that region and stored data is remapped to spare sectors. Here is how you can repair bad sectors on hard drive by running the disk scan program on any Windows Operating system like Windows XP, Windows Vista and Windows 7:Open ‘My Computer’ and right click on the drive volume which is suspected to have bad sectors.Click on the properties option and select the ‘Tools’ tab in the window that opens.Click on ‘Check Now’ under the ‘Error Checking’ section.Another window will open with two check boxes that say- ‘Automatically fix file system errors’ and ‘Scan for and attempt recovery of bad sectors’.Select both the options and click on ‘Start’. Before clicking on start, close all other programs that are running on the operating system. Otherwise the scanning program can only run when you restart your computer next time.Read more on:Hard Drive Data RecoveryFix Bad Sectors on Hard DriveCheck Hard Drive for ErrorsCheck Hard Drive HealthUsing a power back up like a UPS device and running regular disk fragmentation might help in prolonging the life of your hard drive and prevent bad sectors from occurring. Never shut down your computer by directly switching the power switch off. Always switch it off by selecting the shut down option. This may prevent the bad sectors that are created due to improper shut down. Hope this article has left you in no doubt about how to repair bad sectors on hard drives.

While upgrading the computer hardware or changing your desktop computer altogether, you may want to get rid of your old hard drive. But if have stored any personal, business related or any other sensitive data to your hard drive, just deleting it will not ensure complete safety of your data. For that you will have to wipe hard drive clean in such a way that the data cannot be retrieved at all.

What is the Problem with Just Deleting

There is an index or a record of addresses that tells your operating system where the data is stored on the hard drive. When you delete or shift delete any data, just the reference to the data is deleted and the operating system is told that the data no longer exists. Although the data is still there on the hard drive and can be retrieved with the help of simple software applications called data recovery software. Even formatting the hard drive does not destroy the data completely, it only makes recovering the data a little difficult. So if you ever format a drive by mistake, worry not, you can get all or most of the data back.

How to Wipe Hard Drive Clean

The best way would be to physically destroy the hard drive like pentagon does. If you can’t do that, there are several other options too. Reformatting and installing the operating system again is one of the ways to ensure basic secure deletion of your sensitive data. If you are giving away your old computer to someone you know, this method is sufficient. But if you are selling the hard drive on line or to anyone who pays, you should consider some other options. There are several softwares that you can use to clean your hard drive. Some free applications like shredders, can be used but are less or sometimes completely useless. Other more effective software clean your drive by overwriting garbage information to it. Norton’s SystemWorks includes an application called Wipe Info, OnTrack’s DataEraser offers a similar feature. There are more such applications on the Internet. Make sure that the utility or program you use, provides an option to erase free space that is temporary files. Other means of destructing data are degaussing and destruction. Degaussing is the process by which the storage media is subjected to a powerful magnetic field to remove the data on the media. Degaussing may render your disk disabled. Consequently, you should use this method if the disk is not going to be reused.

Make sure you have taken a back up of the data that you will be needing again before you wipe hard drive clean. Free shredder utilities do not offer complete eradication of the data. So if the data is something related to your business, do not take any chances and opt for a paid version. Also, check if you have the hardware driver disks with you, as without them some of the computer peripherals will not work. If you do not have much technical knowledge about computers its best to take it to an expert who will do the job for you. Plus, the methods vary for different operating systems and different hard drive types, but most of the above mentioned will work for almost all of them. If you are unsure of any of the methods it is suggested that you do not apply them.

Hard drive is a non volatile storage device, used to store digital data. The first hard drive was made by IBM in 1956. Over the years, that we have been using the computer, there may come a time, when the hard drive may run out of space. If you want to install a new software, then it is better to check hard drive space, to know availability of space on the hard drive. If you are indeed running out of space, you may want to know how to clean computer hard drive. Un-installing software, that are not required, will help you to have free some space on the hard drive. There are be some out there, who may want to know, how to check hard drive space just out of curiosity (well I am one of them). Whatever be the reason, checking hard drive space will not harm the system, but may prove to be helpful to you.

How to Check Hard Drive Space

There are a different ways to check the space available on the hard drive. Let?s see the steps, you will have to take for the same.Click on “Start” located in the left hand corner.Then go to “My Computer” from the menu.Right click on the “Local Disk (C:)” icon.Then select “Properties” from the drop down menu, that appears.You will be able to see the “Used Space” and “Free Space”. With this you will know the amount of space, you have used and the amount of space, that is available.Repeat the same on the other drives on your system as well.In the other way to check hard drive space in windows, the change is only in the initial steps. You will have to double on the “My Computer” icon on the desktop. There you will the see the hard drive, along with the partitions if any. Right click on the hard drive and select “Properties” from the drop down menu. With the window, that pops up, you will be able to see all information, along with a pie chart.

How to Check Hard Drive Space on Mac

If you have a Mac, then the method to check hard drive space on the Mac is different from the way it is done in Windows. Like is the case with Windows computer operating system, there are a couple of ways to doing the same in Mac as well. The easiest way is to open your hard drive folder from the desktop. When a window opens, see at the bottom of the status bar. You will see the status being displayed, about the amount of space available on the hard drive. Let?s see the other way now.Go to System Profiler.Then click on the Apple icon located in the top left corner of the screen.Now click on “About This Mac”.In the window, that appears, you will come across a button “More Info…”. When the new window pops up, to go the Hardware tab and then to Serial-ATA tab.You will now be able to see information, about the available space on the hard drive, whether the hard drive is writable or not, type of file system, among other things.How to Check Hard Drive Space in Linux

Finding out the hard drive space on Linux and Unix is indeed easy. The command to use at the shell prompt is “$ df”. It will display the amount of disk space available on the file system, which will also have each file name argument. If there is no file name available, then the space available on all currently mounted file systems will be displayed.

Now that you know how to check hard drive space, you will be free to install a number of software. If you are running out of space, then you can uninstall the software, which you do not require.

Before we get to the various different types of hard drives, let’s go through a brief session on what hard drives are. Previously known as hard disk drives, hard drives are storage devices for backing up digital data. The best feature of these devices are that they are non volatile as they are capable of retaining stored data upon them even when unplugged from the power source, unlike RAM which loses all information as soon as the computer is shut down! Data if encoded magnetically upon such drives using read / write heads. These heads hover above the disk platters as if they are riding upon an air valve. Broadly, there are two different types of hard drives – internal and external. What is an internal hard drive? An internal hard drive is the disk drive that is inbuilt within the computer / laptop and which comes as a part of the factory assembly of the entire system. What is an external hard drive? Let’s find out.

External Hard Disk Drives

An external hard drive is that which can be externally connected to the computer / laptop using USB ports. Portable hard drives and pen drives are such examples of external hard drives. EIDE, SATA and SCSI are all examples of external hard drives and these are being discussed subsequently. These types of external drives are usually enclosed within portable disk covers and the connecting interface may be any among USB, eSATA, eSATAp, etc.

Now, let’s proceed towards discussing the various different hard drive types based upon narrower technological details and features.

What are the Different Types of Hard Drives?

Based upon technical details and functionalities, there are four major types of hard drives that are commercially available as of this date. These four hard drive types are being discussed below under separate headings.

Enhanced Integrated Drive Electronics: More commonly known as PATA (Parallel Advanced Technology Attachments), EIDE’s are not very popular these days as advanced technologies in the form of SATA have captured a lion’s share of the hard drive consumer market. The labels on these drives correspond to the interface variant which is involved to connect the CPU board and the drive together. The latest and faster EIDE variants use cables of 80 wires, although the older versions worked mostly on 40 wire cables. The connector used in these drives are usually 40-pin variants. Formatting a hard drive of this category may take a longer time due to slower speed.

Serial Advanced Technology Attachments: Commonly known by its abbreviated name SATA, these hard drives are identified apart from their precedent, EIDE or PATA due to a different variant of connector incorporated in the former. Also, EIDEs are bulkier than their successors, SATA and the former’s data interface is slower than the latter’s. Also, SATAs score on the power consumption front as they consume lesser power than EIDEs. Also read about eSata external hard drive for more updates on this type.

Solid State Drives: Abbreviated as SSD, these hard drives are composed of stationary parts. There are no moving paraphernalia in these drives, as opposed to other hard drive variants which usually include magnetic disks that rotate as they back up data. SSDs are equipped with semiconductors which perform the task of rotating magnetic disks to pile up saved data. The absence of moving parts within the drive means it is less susceptible to break downs and their processing speed is faster than other drives that employ the conventional storage methods! This is what ranks SSDs as the best external hard drives as far as speed and durability is concerned!

Small Computer System Interface: Known by its short form SCSI, these drives function in similar ways as EIDEs insomuch as they employ rotating magnetic disks to write and save data upon them. The major difference between SCSI vs EIDEs and SATAs is the fact that SCSI drives spin faster than either of the aforementioned hard drive types. Faster spin rate means faster data processing and storage. However, the flip side of fast rotation rate is that the faster the disk rotates, the faster the drive is likely to break down! This makes attempts to repair bad sectors on hard drive difficult for these types.

That was a bird’s eye glance over different types of hard drives. It helps to know what type of hard drive your system is using as some basic knowledge about hard drives, like how to reformat a hard drive, would help you troubleshoot that corrupted hard drive yourself! However, if you are not a computer hardware engineer, soliciting professional troubleshooting is a better idea! Why compromise your entire system for the sake of a malfunctioning storage device? Happy computing!
