I have a 8MM SCSI Tape drive attached to my linux server that was created by SUN.....cant determine the name though. I am able to run the basic commands such as :

mt status
mt retension

But when I attempt to do any type of writing to the tape, I get Illegal Write errors from the drive, and Input/Output Errors returned to the kernel. Does anyone have an expertise in this? I havent dealt with tapes in 3 years or so......
