STC drives were the reliable ones. Ever use Potter drives in the late 1970s or in the 1980s?

The only thing they did was to throw the tape away (forget about erasing it first) And goto a new box of tapes and set up the initializations. I don’t even recall if they told TMS. We tried to put a tape degausser in the budget but it was never approved. Somehow an auditor got involved and suddenly a tape degauser showed up. I might be a cynic but I don’t think they ever used it. Our big boss was trying to show the board how he tried to save money. They sort of forced him into getting STC (now STK) tape drives. All of a sudden some of our jobs were getting S237 (block count did not match trailers), STC said we had bum tapes, we went through all sort of shenanigans to prove they weren’t. I had to write a program that counted blocks and compare it the tapes count. The entire mess ended up with STC getting kicked out and IBM drives were brought back in. Of course never a S237 with a IBM drive. Our tape library while not super large it was large and finally management finally figured it out in order to get good people you had to hire/pay for them.
