I have a Sony AIT-3 (SDX-700C) tape drive attached to my Windows XP computer, via an Adaptec 29160 SCSI controller. I would like to write to and read from this tape drive using Cygwin commands such as "tar". The drive is recognized in the Windows device manager under "?Other devices/?Sony SDX-600C SCSI Sequential Device". Under Cygwin, I have used the command "mount //./tape0 /dev/st0", and the device appears to be mounted in /dev/ as st0. However, when I attempt to write using "tar", the tape unit is unrecognized, and no writing occurs. Any help out there?
