Well, back when I was in charge of 250 or so uVAX II's and Vaxstation 2000s at UCB, we had perfectly good TK50s and their cartridges misbehave so frequently with regard to the detached-follower problem that all of us carried around a little kit with us for disassembling the drives and removing tape followers (one of the techs even repaired the tapes, though I generally just binned them and said "sorry man, your data's toast" :-). For those who don't know how the TK-50s used to work, the tape cartridge has this little stiffened metal tab at the very end of the tape which the drive latches on to when it's feeding the tape in. Apparently the bond between tape and metal tab wasn't all that great back then and would frequently get separated from the tape, rendering the drive (which retained the tab) inoperable. Even more fun was when the tape came detached from the cartridge at the other end, after you'd read an entire tape into the drive. You had to take the drive apart and wind all that tape back off again. "The horror... the horror..." :-) Jordan
