Mondoarchive won't recognize tape drive


I have done this many times on redhat 9.0, but it is my first time on fedoracore 4. I can see the device in dmesg so I'm pretty sure its there and is at st0 just as mondo recomends. Everytime I try it or a another device it says "---FATALERROR--- Unable to open tape device. If you haven't specified it with -d, do so. If you already have, check your parameter. I think it's wrong."

I'm lost it is there!


dmesg output:

You can diagnose SCSI tape device mapping using the mt command. mt stands for magnetic tape. mt also works on IDE tape drives. If you haven't installed the mt command then do so. It is very useful for working with tape drives.

Then put a tape into the tape drive and enter the following command.
Code:
mt -f /dev/st0 retension
That should cause the tape drive to wind the tape to the end and then to rewind it to the beginning. This is a good thing to do from time to time to prevent the tape from sticking to itself near the end of the tape. Of course the point of doing this is to test whether the tape drive will respond to commands sent to /dev/st0. Write back and let us know the result.
