Bon Soir Henri,

Many thanks for your most informative post. I'm beginning to think I should 
stick with LTO, but it really is a pain. I'll see what I can find out about 
external LTO drives and see if they're any easier to install than the 
internal variety. I only say this because I have a rack full of unused LTO 
tapes already.

Many thanks,
