Types of hard disk failure

Before I go further to tell you about hard disk repair I should tell you there are two types of hard drive failure – physical and logical.

Physical failures are caused by a failure of the electric motor or the drive itself – the moving parts. They can also happen because of a major head crash (if computer was dropped or jostled while it’s running).
Logical failures are caused from corruption in the file system. It can happen if you have accidentally deleted an important registry entry or formatted the drive improperly, or if you have a nasty virus, this may cause the BIOS to recognize the drive, but it won’t boot.

 

When you need Hard Disk Repair :

let’s have a quick look at the situations may arise due to hard disk failure and when you should go for a Hard Disk Repair –

 

1.Disappearing files:

Files can be lost due to mechanical problems with the disk itself, and in some cases, you’ll be able to tell as the disk usually makes some out-of-the-ordinary noises when things are going haywire.
2.Computer freezing:

A computer freezing is a common incident, and it’s almost always solved by a quick reboot. However, if you find that it is getting more and more frequent, your hard drive could soon to die.
3.Corrupted data:

If you’ve downloaded and installed files without a hitch, but suddenly out of nowhere, files have become corrupt, it’s possible that your hard drive is experiencing a gradual failure.
4.Bad sectors:

A sector on a hard drive stores a certain amount of data accessible by the user. There are two types of sectors, a hard and soft sector. In most cases, Windows is able to repair a soft bad sector, as it’s almost always related to a software mishap. Formatting the drive will almost always fix this. But, if it’s a hard bad sector, this indicates physical damage, which can not be repaired. You can manually check for a bad sector by right-clicking the drive in My Computer. Select “Properties” and then navigate to the “Tools” tab. Finally, under “Error Checking” select the “Check” button. Windows will identify any sectors that have gone bad. As mentioned, Windows will try to fix it with a restart and doing some behind-the-scenes magic, but if that does not work, you could be, once again, experiencing gradual failure.
5.Sounds:

If your hard drive is making sounds that you aren’t familiar with, this could also be bad news, particularly if it’s a grinding or screeching noise.
For legacy troubleshooting, please see the “Legacy Troubleshooting” section at the bottom of the article.

 

Typical symptoms associated with hard disk drive failures

 

Laptop Hard Disk

 

The front panel indicator lights are visible, and the display is present on the monitor screen, but there is no disk drive action and no boot-up.
The computer boots up to a system disk in the A drive, but not to the hard drive, indicating that the system files on the hard disk drive (HDD) are missing or have become corrupt.
The computer does not boot up when turned on.
An IBM-compatible 17xx error code is produced on the display.
No motor sounds are produced by the HDD while the computer is running. (In desktop units, the HDD should generally always run when power is applied to the system—however, this does not apply to all desktops or portables when advanced power-saving features are used.)
A HDD Controller Failure message appears, indicating a failure to verify hard disk setup by system configuration file error.
A C: or D: Fixed Disk Drive error message appears, indicating a hard disk CMOS setup failure.
An Invalid Media Type message appears, indicating the controller cannot find a recognizable track/sector pattern on the drive.
A No Boot Record Found, a Nonsystem Disk or Disk Error, or an Invalid System Disk message appears, indicating that the system boot files are not located in the root directory of the drive.
The video display is active, but the HDD’s activity light remains on and no bootup occurs, indicating that the HDD’s CMOS configuration information is incorrect.
An Out of Disk Space message appears, indicating that the amount of space on the disk is insufficient to carry out the desired operation.
A Missing Operating System or a Hard Drive Boot Failure message appears, indicating that the disk’s MBR is missing or has become corrupt.
A Current Drive No Longer Valid message appears, indicating that the HDD’s CMOS configuration information is incorrect or has become corrupt.

Hard Disk Repair

If you want to repair your Laptop hard disk or computer hard disk only following this blog will not be enough,It may require in you some knowledge about computer hardware :

 

HDD Configuration Checks

While booting up the system, observe the BIOS’s HDD type information displayed on the monitor. Note the type of HDD that the BIOS recognizes as being installed in the system. Possible error messages associated with HDD configuration problems include the Drive Mismatch Error message and the Invalid Media Type message.

Check the drive to ensure that it is properly terminated. Every drive type requires a termination block somewhere in the interface. For Integrated Drive Electronics (IDE) drives, check the Master/Slave jumper setting to ensure it is set properly for the drive’s logical position in the system. Remember that there can only be one master drive selection on each IDE channel. If both drives share an interface and are set to the same selection, neither drive should work.

If you have more than one device attached to a single interface cable, be certain that they are of the same type (for example, all are Enhanced Integrated Drive Electronics [EIDE] devices or all are ATA100 devices). Mixing IDE device types create a situation in which the system cannot provide the different types of control information each device needs. The drives are incompatible and you might not be able to access either device.

If the drive is a SCSI drive, check to see that its ID has been set correctly and that the SCSI chain has been terminated correctly. Either of these errors results in the system not being able to see the drive. Check the CMOS setup utility to ensure that SCSI support has been enabled along with large SCSI drive support.

Basic HDD Checks

The first task is to determine how extensive the HDD problem is. Place a clean boot disk or an emergency start disk in the A drive and try to boot the system. Then execute a DIR command to access the C drive. If the system can see the contents of the drive, the boot files have been lost or corrupted, but the architecture of the disk is intact.

Modify the DIR command with an /AH or /AS switch (that is, DIR C: /AH or DIR C: /AS) to look in the root directory for the system files and the COMMAND.COM file. It is common to receive a Disk Boot Failure message onscreen if this type of situation occurs.

In Windows 9x and Windows Me systems, if the clean boot disk has a copy of the FDISK program on it, attempt to restore the drive’s MBR (including its partition information) by typing the following:

Providing that the hard disk can be accessed with the DIR command, type and enter the following command at the DOS prompt (with the clean boot disk still in the A drive):

This command copies the IO.SYS, MSDOS.SYS, and COMMAND.COM system files from the boot disk to the hard disk drive. Turn off the system, remove the boot disk from the A drive, and try to reboot the system from the hard drive.

If the system cannot see the drive after booting from the floppy disk, an Invalid Drive message or an Invalid Drive Specification message should be returned in response to any attempt to access the drive. In Windows 9x systems, use the FDISK utility to partition the drive. Next use the FORMAT /S command to make the disk bootable. Any data that was on the drive is lost in the formatting process, but it was already gone because the system could not see the drive.

The process for checking the hard drive on a Windows NT, Windows 2000, or Windows XP computer is similar to the one for checking a Windows 9x-based system. In Windows NT and Windows 2000, the partitioning process is performed through the Disk Administrator and Disk Management utilities, respectively. These utilities perform all of the basic functions that the FDISK utility does. For instance, both utilities can be used to partition drives and both show you the basic layout of the system’s disks.

These disk utilities can also provide advanced functions associated with  enterprise (large-scale, business-oriented) computing systems. The Disk Administrator and Disk Management utilities can be used to create both traditional primary and extended partitions for MS-DOS/Windows 9x systems or for Windows NT and Windows 2000 systems. They can also be used to create volumes (partitions that involve space on multiple physical drives).

The Windows 2000 and Windows XP Disk Management snap-in is located under the Computer Management console. To access the Disk Management snap-in, click Start, Settings, Control Panel, Administrative Tools. Double-click the Computer Management icon, and then click the Disk Management entry. Because working with volumes is a major administrative task, you must be logged on as an administrator or as a member of a Windows 2000 Administrators group to carry out this procedure.

Formatting Volumes in Windows 2000 and Windows XP

Formatting a partition or volume prepares the logical structure to accept data by creating the file system in it. If a partition or volume has not been formatted, it does not contain a file system and it cannot be accessed through the operating system or any applications. In the Windows 2000 and Windows XP environment, you can perform many actions to initiate formatting, including the following:

Use the Volume Creation Wizard in the Disk Management utility when the volume is created.
In the Disk Management utility, right-click a volume that has already been created, and then click Format from the shortcut menu.
In Windows Explorer, right-click the desired drive letter, and then click Format from the shortcut menu.
At a command prompt, type the command Format along with the appropriate switches.

CAUTION

It’s okay if you have done it previously but if this is your first time in hard disk repair then these cautions are a must for you :

If you format an existing partition or volume, any data residing in the structure is lost. The Windows XP Professional operating system protects its system files by preventing the system and boot partitions from being formatted.

HDD Hardware Checks
If you cannot access the hard disk drive, and its configuration settings are correct, you must troubleshoot the hardware components associated with the hard disk drive. These components include the drive, its signal cable, and the Hard Disk Controller (HDC) on the system board.

Check the HDD signal cable for proper connection at both ends. Exchange the signal cable for a known-good one. Check the Master/Slave jumper settings to ensure they are set correctly. Determine whether the system is using the Cable Select option. This setting enables the system to dynamically assign the master/slave arrangements for multiple IDE drives. Likewise, check the ID configuration settings and terminator installations for SCSI drives.

Although it might seem logical to replace the hard drive unit at this point, it is quite possible that the hard drive might not have any real damage. It might have simply lost track of where it was, and now it cannot find its starting point. In this case, the most attractive option is to reformat the hard disk. This action gives the hard drive a new starting point from which to work. Unfortunately, it also destroys anything that you had stored on the disk.

If the reformatting procedure is not successful, or the system still doesn’t boot from the hard drive, replace the hard disk drive unit with a working one.

 

Tips :

Keep one updated antivirus and one updated firewall always running on your system. Attacks can damage disks by overloading.

Too many heavy anti-viruses and firewalls or software that essentially do the same thing, installed on your system, just because they were freely available on some sites, or have been offered to you by your corporation, is not going to find much favor with your hard disk’s health. Two anti-viruses, for an instance, especially heavy ones like Norton, constantly running scans can be torturous on your hard disk’s mechanical parts.

If you feel your system is running slow, diagnose the disk and see if it’s the excessive fragmentation that’s forcing your system to do too much work to squeeze files and data here and there in between those tiny free gaps. If you let your system run on an excessively fragmented disk, not only will it run slow, your disk’s life too is going to get reduced drastically. Diagnose your disk periodically or every time you think your system is slow, and defrag it.

Go to Start menu, and type “msconfig”. Go to the Startup tab. Here uncheck all the programs that you don’t actually need loaded at the start up and keep sitting in your RAM. A good example is audio players like WinAmp.

Most people think it’s cool to downloading fancy utilities to clean the disk off temp files, while windows very own Disk Cleanup, a little slow but more than fits the bill for most practical purposes. Use it to free up spaces on your disk.

Always look for smaller footprint utilities, also check for reviews. Rule of thumb, if some utility works for you don’t switch to another just for better looks. Classic comparison is that of CCleaner, an old proven compact utility, and PC Cleaner an unnecessarily heavy utility that’s known to be poorly written.

Free game trials, software demos, rarely used utilities, never used services; remove them all from your PC. If you must keep them, store them in an external hard disk instead.
