hi Freinds,
Use NORTON DISK DOCTOR it will Fix HDD Bad Sectors.

or do this:
1: Double-click on “My Computer”.
2: Select the disk/partition that you want to diagnose and repair.
3: Right click on the disk/partition you selected and click on “Properties”
4: Choose the “Tools” tab.
5: Click the “Check Now” button under “Error Checking Status”.
6: Depending on your type of Windows, choose “Thorough” or “Scan for and Attempt Recovery of Bad Sectors.”
7: Click Start.

You can repair bad sectors permenently insted of blocking them you can regenrate bad areas sucsesfully.. by using a software called Hdd regenerator this software is a freeware and unbelievable you can easily find it on you windows crystalxp cd insert it and on boot menu go on hiren cd,s then enter on hard disk tools then on hdd regenarator it will take 1 or 2 hour to procseed if you can,t find windows crystalxp v.2 cd then search on www.google.com.pk type hdd regenarator on search bar

Norton Disk Doctor, which is a part of Symantech suite simple uses chkdsk for NTFS volumes. Don't bother installing it.

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.

Many thanks to the posters who have flagged JFileRecovery for dealing with discs that have this error. It worked for me, allowing me to salvage several old mini-DVDs containing video that I had never been able to download via either the camcorder or my PC's DVD drive.
