Chances are 100% in my book. I do have some experience doing it and it's a royal pain in the b*tt. > The general opinion of quite a number of people is that longit- > udinally-recording drives (QIC, DLT, MLT (sp?)) are much more robust, > becuase of them being KISS.

I have yet to loose a QIC tape. Even DLT can get mangled, most of the times this is from people dropping cartridges or getting the leader pickup thingie in the drive coming loose from it's hook. Easy to fix if you know what you're doing. I have an Exabyte 8200, a DLT2000 and a Tandberg 2Gb QIC drive so I can do some comparing. As you can guess I like the DLT best ;-) _ ____________________________________________________________________ | / o / / _ Bulte email: wilko@yedi.iaf.nl http://www.tcja.nl/~wilko |/|/ / / /( (_) Arnhem, The Netherlands - Do, or do not.
