Bad Sectors on Hard Disk
 
Hi

Howto scan and fix Bad Sectors on Hard Disk without damaging data?

Use the badblocks program. See man badblocks

If your drive is about to fail you might consider replacing it as fast as possible.
You can use a tool dd_rescue to copy the entire disk if you have trouble accessing certain files.

AS others have said, backup first then try to fix.

I'd like to scan a hard disk just READ ONLY using badblocks.
Knows someone if:
Code:
# badblocks -s -n /dev/hda
or
Code:
# badblocks -s -v /dev/hda
will not damage any data on the hard disk?

Code:
man badblocks
...
By  default  only  a  nondestructive  read-only  test  is  done.
