I have come across disks before which work just perfectly if you read
them using a linear read, but on which bad sectors are found repeatably
if you perform random access reads. Badblocks is a sequential scan, and
in cases where the disk alignment is off, it's quite possible that media
errors will be missed by it but hit by a random access later on.
