Re: asking for help with getting the tape drive to work

["Aaron M. Stromas" <astromas@us.oracle.com>]

dean,

thanks for pointing out the -f . i'm still not through with the problems:

     mortirolo:/# mt -f /dev/ht0 status
     mt: /dev/ht0: No such file or directory
     mortirolo:/# mt -f /dev/hdd rewind
     mt: /dev/hdd is not a character special file

/dev/hdd appears to be the tape drive but the device file is wrong:

     mortirolo:/# file /dev/hdd
     /dev/hdd: block special (22/64)

can somebody suggest how to make the correct device file? btw, there's some
info in dmesg:
