burnin tries to write beyond disk size #22

Just ran a couple of burnin's. One against a 2TB drive I'd repaired with bbf, the other against a brand new 4TB. Both reported errors that look like bbf was attempting to write beyond the final sector on the disks:

./bbf -t ata -S 256 -c W1H2YHVH burnin /dev/sdk

Should be addressed now though one of my drives still acts a bit weird at the end of the drive when larger steppings are used. I'm not able to figure it out but that drive has known issues so it could just be busted.
