The output will be written in QIC120 format (which >will give you 120MB per tape). > This is either incorrect, or system-dependent at best. Sun's _Tutorial on 1/4 Inch Tape Drives_ says, "The 150 Mbyte tape drive writes 18-track tapes in the QIC-150 data format. This tape drive uses 3M DC6150 (formerly DMDC600XTD) cartridges. This drive can also read tapes recorded in the QIC-120 data format on compatible cartridges, but does not write data in this format." Reading between the lines in the same tutorial suggests that the QIC-120 format is 15 tracks, while QIC-150 is 18 tracks. >Conor P.
