The QIC-80 tape device is different from normal tape devices. You need a special program to read/write data from/to the tape. Try 'man ft'. Usually you do something like: ft | tar xvf - # restore stuff tar cvf - /home | ft # write a backup of /home The /dev/ft0 device is only a low level interface to the floppy tape. All error correction and sector handling is done in ft. I personally prefer the way they did it under Linux with the ftape driver. But on the other hand, floppy tapes are braindead anyway. It would be nice if one could adopt the Linux ftape driver for FreeBSD. But I think there were some major difficulties I already forgot (Things for timing/scheduling inside the kernel are too different). As far as I heard there is no ongoing development to improve 'ft'. So, 1 Mbit/s controller and Travan tapes will not be supported in the near future. Best solution would be a cheap SCSI-Streamer. : : Thank you in advance. : : Thanva Ciao Guido
