You shouldn't have to do the setdensity operation; the drive ought
to be able to read the 6250 BPI drive in any event. What happens
when you try to read the 6250 BPI tape?

Historically, the SCSI commands for selecting tape drive density have
been either ignored or misinterpreted by everyone throughout the years.
