Hi,

I would like to check for bad sectors in my harddisk and if possible, recover it. Can anyone specify a tool for that?

I am using Fedora 16. Toshiba Satellite L510 laptop.

Thanks in advance.

Open

Activities -> Applications -> Accessories -> Disk Utility

Then select on the left column the disk you would like to analyze and repair and push the

Check Filesystem

button. If you feel better with command line you may probably give this short guide a try.

we should use e2fsck , for example:

e2fsck -c -k /dev/mapper/VolGroup-lv_home
  • -c This option causes e2fsck to use badblocks(8) program to do a read-only scan of the device in order to find any bad blocks. If any bad blocks are found, they are added to the bad block inode to prevent them from being allocated to a file or directory. If this option is specified twice, then the bad block scan will be done using a non-destructive read-write test.
  • -k When combined with the -c option, any existing bad blocks in the bad blocks list are preserved, and any new bad blocks found by running badblocks(8) will be added to the existing bad blocks list.

  • -l As a result, it is much simpler and safer to use the -c option to e2fsck, since it will assure that the correct parameters are passed to the badblocks program.

Hello, after fight some months or even 1 or 2 years with an HDD with bad blocks , I found this [1], after some e2fsck the bad block list was cleaned etc , but in unix.stackexchange.com is state that "Filesystem badblock lists are obsolete" , so the correct way to deal with bad blocks is using smarttools [2]
