[newbie] Tape Backup drive?

[Mick]

Friends, Romans, Newbies, Lend me your ears...

I had an old Conner backup drive (Backs up onto 120mb QIC tapes) that I have 
installed into my machine running LM 7.2 and Win98. I ran Hardrake and it 
didn't find it, I tried installing Arkeia backup software but that won't let 
me log into it? What is the procedure for setting up a tape backup drive in 
LM? 
All help gratefully appreciated.
