Ah. I think I'm too much of a control freak then. I thought I could just use 
8 tapes and keep the other 2 as spare ones: I wanted to use tape 1 on day 
1, tape 2 on day 2 etc. But if you're right, Amanda uses every tape in the 
tapecycle before it starts overwriting the first one, which means Amanda 
will tell me which tape it wants when. Too bad for my numbering scheme 
then.

Thanks!

Kind regards,

Hans
