Tape drives degrade, plastic goes brittle, rubber pickup wheels just turn to dust, springs lose their tension. I've seen old LTO drives where the read heads were covered in magnetic oxide from the tapes (and the oxide then gets onto the pickup wheel and ruins the tension so the tape doesn't read properly and you're risking it being chewed up). You can only buy old kit on eBay for so long before it's useless. Anything with moving parts is a disaster waiting to happen.

Yes, but I did specify "keep in working order," not "buy some old ones on eBay." These aren't casual hobbyists, but large corporations with whole staffs of technical departments.

And I also am talking about large corporations. I've worked on projects where IBM was buying old kit on eBay to keep a couple of ancient servers running. The tape drive I referred to belonged to a major hospital (who, incidentally, were running a 20-year old VMS system that was a lot less trouble than the tape drive but was still the cause of an 8-day outage). You just can't replace the guts of a tape drive unless you have access to the original manufacturer's technical department and spares.

No, you're not talking about a large corporation. You're talking about a hospital that called in IBM for help with a failing system, instead of having them keep it in working order all along.
