Viper 150mb SCSI QIC tape drive. In the drive was a DC600A tape cartridge. What's the
difference between DC600A cartridges and the DC6150 cartridges I remember seeing years
ago? I've tried reading this tape, but it doesn't appear to contain readable data
- but then again, it may not have ever been intended for this drive.

DC600A = 9 tracks 60MB (600 ft tape), 550 Oersted
DC6150 = 18 tracks, 150MB (600 ft tape), 550 Oersted
I'd guess you can do 150MB on a DC600A as long as it is bulk erased
first (I'd imagine the
individual tracks are narrower on a QIC-150 formatted tape vis a QIC-24
format (60M)
tape (much like 1.2M 5.25" floppy tracks are narrower than on the 360K
drive (which led to
all sorts of 'fun' writing 360K disks on a 1.2M drive!)))
