It also has the advantage that you can return the CRC/checksum and partially read blocks. Most SCSI tape drives don't
return the data if the read doesn't succeed. Some drives have a seismic mode for dealing with oil exploration tapes
which returns anything read, but it has it's own set of problems (it will happily return garbage if the density doesn't
match)
