I also have several crates of 9-track tapes, QIC-24 tapes, QIC-150 tapes, and various generations of DDS DAT tapes. I don't think that I have anything worth keeping on these as I've transfered worthwhile stuff to newer media over time. Hard to believe that the entire contents of a 9-track tape fit in a negligible amount of memory these days. The thing that's kept me from getting these out of my basement is that I'd prefer to erase them first, just in case. Does anybody have experience with a decent bulk tape eraser? Jon
