Hard drive bad sector

[S.rahman]

Hey friends, i hv a problem to my hard drive.. It got bad sector. How can i remove bad sectors or solve my problem??? Any 1 help

Use Checkdisk with the parameter /f, let it reboot and flag the bad sectors. If the problem persists or the harddisk is old, buy a new one.

Before you do anything...make sure to back up all important personal data; photos, docs, music, etc.

if chkdsk /r don't work then try Hard drive regenerator ,The trial version will repair only a few bad sectors , If the bad sector is unrepairable the it show be added to the bad sector list that every harddrive has.

when a bad sector is added to the list ,It should be ignored by the drive and appear the drive has no bad sectors

Bad sector is a hardware problem.
When you copy files to your hard drive, Windows randomly fills the empty sector on the hard drive. The danger of this is when the data ends up on the bad sector.
Software that claims to repair bad sector simply blocks the sector from being used.
I have long heard that when a hard drive has bad sectors, it will continue to increase but sure if that is a myth or not.

When bad sectors starting showing up on the HDD in my year old HP laptop, they replaced it, rather than trying to fix it.

[Raymond]

Yeah if there is warranty, ask your manufacturer to replace the drive.

Bad sector is a sector which can not be read normally due to physical damage but can be read by some data recovery methods.

Bad sectors can be caused by the followings
1. User switches off (or resets) PC without shutting down properly
2. User attempts shutdown, but shutdown fails to complete
3. Power fails, or is accidentally switched off

Also

* Bad RAM
* Bad processor fan
* Overclocked PCI bus

Operating system manages direct disk access & drivers for the particular hardware in use. flaky operating system and device driver code can and has caused data corruption through wild writes and file system insanity. Data corruption by overwriting arbitrary areas of raw disk with garbage by Malware can do the same.
You can't recover bad sector using software as they are physically damaged. It will be better that take backup of important data as soon as possible.

Two useful monitoring and scanning tools Disk Health Monitoring & HDD Health users.

Some info's:

1. If Error Correcting Codes are not written in a sector , this sector will be treat as bad sector. By doing the low level format it can be fixed by restoring the ecc.

2. Also a bad block can be replaced by the spare, if no spare is available there it will remain bad.

As Raymond said above if you have warranty go to the manufacturer for the replacement. Regards.

In my experience, once you get one bad sector, more problems are not far behind in the coming days and weeks. As drives are so cheap these days, perhaps you should consider a replacement if it's not under warranty. Better to replace now and not have it go when you least expect it.

Have you read the S.M.A.R.T. info on the drive? If so, what does it say, especially 'Reallocated Sector Count'?

I love this sentence... Should be added into the book of famous quotes or phrases
