You can use SMART to check if your disk ever encounter en hardware issue. If it has, it has been recorded so you will know.

You can find more info here on how to use it:

Run e2fsck with the -cc option. It will do a (safe) non-destructive check
for bad blocks

Code:

# e2fsck -cc /dev/sda1

Are you sure its bad sectors you want to check, rather than bad blocks? You may have to so called "low-level" format to update the drives' bad sector table. Download the drive manufacturer's software tools to do this. It will test each sector with a read and write, so it is destructive - you need to backup your data first.
