DLT1 runs as 1/2 the speed of the DLT8000 and has a different # of tracks and density, so the tapes aren't interchangeable. There's a nice PDF file comparing the different drives at http://www.overlanddata.com/mktg.nsf/Lookup/dltdrives.pdf/$file/dltdrives.pdf If you need more than 40gb native per tape, you might want to get SuperDLTs, which will do 100gb native. They just started shipping, though, so they'll be expensive. -- Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
