how to fix a hard disk with bad sector?

Answer 1

In WinXP, go into MyComputer

Right Click your Hard Disk, Choose Properties

Choose Tools/Error Checking

Check Boxes Automatically Fix Errors etc. and
Scan for and Attempt to Repair Bad Sectors

Click Start

This will take quite a while, since it goes thru and checks each track. If it finds bad tracks, it will assign replacement tracks, and try to copy your data. You may lose that data. Then it marks the bad track as unable.

If your data can't be saved, you will have to recover it from a backup or else it is gone. If part of Windows is gone, you may have to do a System Restore.

Before WinXP, look for a utility named Scandisk.

Good Luck

The minute your computer's hard disk starts to act flaky, make sure you have an up-to-date backup. Then you can do some simple diagnostics and repairs. Both Windows and Mac OS come with built-in hard-disk utility software that scans your hard disk for errors and attempts to fix them.


For Windows

Steps:
1. Double-click on My Computer to open the My Computer window.

2. Select the disk that you want to diagnose and repair.

3. Choose Properties from the File menu. You should see the Properties window for the drive that you selected.

4. Choose the Tools tab.

5. Click the Check Now button under Error Checking Status.

6. Depending on your version of Windows, choose either "Thorough" or "Scan for and Attempt Recovery of Bad Sectors."

7. Click on Start.

For Mac OS

Steps:
1. If you're running Mac OS 9.2 or an earlier version, search your hard drive for a file called Disk First Aid. You can use this Apple-supplied utility to verify and repair disk errors.

2. If Disk First Aid says it can verify but not repair your disk because it's the startup disk, you should restart your Mac from the System CD-ROM disc that came with your computer. Hold down the C key during startup to force the Mac to start from the CD-ROM. Older Macs, pre-G3, need to press the Command- Opt-Shift-Delete combination.

3. If Disk First Aid fails to fix all the problems it detected the first time you run it, try running it a few more times

4. If you're running Mac OS X, you'll find that Disk First Aid has been made part of the Disk Utility program, which you'll find in the Utilities folder in the Applications folder. Click on the First Aid tab after launching Disk Utility.

Overall Tips:
Third-party hard-disk utilities do a more thorough job of diagnosis and repair than the software that comes with Windows or Mac OS, but they work much better if you install them before you have a problem.

The two links that I've given below can give you tools to help you with this.

Answer 3

Get a new hard drive and do your best to transfer over any data you can from the bad one. It's not worth trying to correct a bad sector. Save the data to a new drive before it's too late.

Answer 4

Depends on where the bad sector is. If it's a hardware fault, it might be time to invest in a new drive. Otherwise, a repair of the OS might be enough, or you can try to reformat the drive altogether.

If you get any clicking noises, that usually means hardware issues.

If you want to start from scratch, then write zeros on your HD and reformat. To do this, go to your HD manufacturer website and download their disk utilities. They should provide one.
