[HOWTO] Test a hard drive, SDD, or thumbdrive for bad blocks

Warning! This is a destructive test!

Badblock utility writes a value to the drive, reads it back, and compares the two.

Where X is the drive letter: a,b,c,d

sudo badblocks -wvs /dev/sdX

To test a particular partition, X is the drive letter, Y the partition number: 1,2,3,4

sudo badblocks -wvs /dev/sdXY
