Before going straight for badblocks scanning, you should umount all the partition (you shouldn't mount a suspicious disk anyway).
Scan for Bad Blocks
Scan for Bad Blocks
Now that you're done, you may proceed to scan for bad blocks. The command is as follow:
badblocks -v <partition> > badsectors.txt 2> badsectors.logExample:
badblocks -v /dev/sdb3 > badsectors.txt 2> badsectors.logThis will generate 2 files:
badsectors.txt- holding all the bad sectors ID.badsectors.log- holding the text output and report of the scan.
If you have any numbers in badsectors.txt , that disk is having bad sectors.
That's all for badblocks scanning.
