Hi All. I've got a set of AIT-2 drives that I'm setting up, using 50 GB native tapes. As my first tapes have started becoming full, I'm finding I'm only getting just over 25 GB on the tapes. Based on what I've read on the list, it looks like people have found the estimated capacity to be 20 GB, but that when the tape filled they still got the capacity they should be getting. I'm, however, not seeing this. I've got the devclass set to type 8mm, format AITC. Now, here's a possible hitch. Initially, I labeled a whack of tapes before I realized that the format was still set to DRIVE as opposed to AITC. Is it possible that labeling the tapes without the AITC format specified is causing the problem? I suspect not, but ya never know... <shrug> If it is the problem, anyone know a quick'n dirty way to wipe the tapes clean enough (on NT) to allow a clean fresh labelling? Thanks muchly.... Paul
