How to Fix or Repair Bad Sectors of Disk
If you have a trouble with blue-screen on your computer, or your windows can not run properly. This indication maybe refers to the damage of harddisk drive (HDD). Before you buy a new hard drive, you can try to repair or fix bad sectors with several solutions:
1) Disk check tool on Windows
a. On Windows XP. Going to Start, Programs, Accessories, and then click on Command Prompt. And type "chkdsk/R" without quotes (/R is "Locates bad sectors and recovers readable information").
b. Under Windows 9x (95, 98 and Me), you can scandisk. Scandisk has an option to do a surface scan and repair as well.
2) Here is the solution (from OMH):
a. Run a surface scan on the HD to determine where, EXACTLY, the bad sectors are located. Use a program like "Partition Table Disk Doctor"; it found all the bad sectors on my drive were located in 3 seperate areas from cylinder 0 through cylinder 1063.
b. Note the locations of the bad sectors.
c. Partition your HD. (I suggest you use a program like Acronis Disk Director; it will give you the flexibilty and HD information that you will need more so than simple Fdisk.) Make one partition that covers up to and a little bit past the point where the bad sectors were reported. (In my case, that was an 8Gb partition that ran from cylinder 0 to cylinder 1063.) Then make another partition in the area that is NOT affected by the bad sectors. THIS is the one you're going to set as active, format, and prepare to accept your O/S.
d. Now delete the first partition, the one with all the bad sectors on it. Doing so will turn it into "unallocated space". MAKE NO ATTEMPT TO USE THIS SPACE ANY LONGER! Yes, you may have to lose a few gigabytes of space, but it's worth it to have your PC working well again. As I said at the start, this is the method I used that got my HD running perfectly! I hope it helps someone.
3) Using a program or software HDD Regenerator
