Your drive is made up of 512 byte blocks. Your NTFS filesystem probably is
made up of 4096 byte blocks.
Hypothetically, if badblocks tells you that the tenth block is bad, that is not
the same as the tenth block in the NTFS filesystem. It would actually fall in
the second 4096-byte NTFS block since 4096/512=8.

4096 byte blocks?
Why then am I using -b 512 when I do a badblocks command on a NTFS drive? Is
that do with clusters (as opposed to blocks?)
