Summary: You should try to fix bad sectors on your hard drive before trashing it. Starting with "chkdsk" may help.
Before you replace, I always like to try for a repair. Most hard disks actually have some spare sectors they set aside for exactly this purpose. You could get lucky and be able to save a few bucks. • On Windows XP, I'd start with a "chkdsk /R". (/R: "Locates bad sectors and recovers readable information"). Fire up a Command Prompt to run that command. You can access Command Prompt by going to Start, Programs, Accessories, and then click on Command Prompt. Under Windows 9x (95, 98 and Me), I believe scandisk has an option to do a surface scan and repair as well. Another highly regarded option is a product called "SpinRite" available at Gibson Research which may also do the deed. If those options both fail you, well, new hard disks aren't that expensive these days. • Recent Comments
how can i remove he bad sector by a boot cd I have what I believe is a good workaround solution to bad sectors on a HD. I just finished doing it to my 40Gb Quantum HD, which previously was so filled with bad sectors that I could not reinstall Windows, and it is now working flawlessly! Here is my solution: 1. 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. 2. Note the locations of the bad sectors. 3. 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. 4. 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.
