Check hard drive for bad sectors in Linux
Check for bad sectors with status
sudo badblocks -v -s /dev/sdX-
-v: Verbose output, lists bad sectors.
-
-s: Shows progress as a percentage of completion.
- For a non-destructive test, use -n instead: sudo badblocks -n -v /dev/sdX.
- To save bad sector list: sudo badblocks -v -o badsectors.txt /dev/sdX.
If you need larger block sizes use this:
sudo badblocks -v -s -b 4096 /dev/sdXThis will give you 3KB block sizes.
