FWIW, my employer got 7 PC's with the HP1553A's in them...and has had trouble with tapes jamming in some of them.

I've got a Sony SDT-5000 on my machine...I use 120m tapes all the time with it and I've never had any trouble, except for that time I tried using audio DAT's in it...:( It isn't as fast as the HP drives, but it does seem to work reliably. (I'm not sure what kind of throughput I get on average...Sony's web page says 366K/sec without compression...and it does have a meg of buffer on board. Here's the URL: http://cons3.sel.sony.com/SEL/ccpg/storage/tape/t5000.html ) Ken -- Kenneth Merry ken@ulc199.residence.gatech.edu Disclaimer: I don't speak for GTRI, GT, or Elvis.
