Tapetype question

[Bill Delphenich]

I want to create the tapetype for the 40/80gb DLT drive that came in my
Dell 4400 server. I am not sure what exactly it is, so I was just going
to create my own tapetype.

However, when I do "./tapetype  -f /dev/nst0 -t DELL_DLT" I get errors
on usage and it quits. I have tried every variation of I can think of to
get it to go, but still no joy.

What obvious thing am I missing here?

Thanks.
