It can't be 16000bpi, since my DC-6525 tape is 1020ft long. By my calculations, it would have to be more like 44975.68628 bpi (assuming 1M = 2^20) So, unless I'm wrong, /usr/src/sys/scsi/scsi_tape.h should have the QIC-320(525?) comment altered to read just QIC-320, and maybe some code adjustments? Thanks
