Before putting rare tapes in old - even yet unused - drives: TEST THEM for some time.
I've had the driver roll of a 6250 drive literally desintegrate and spread a lot of goo on the tape. As it seems, there's a friction clutch inside the driver roll and either the resin inside or the rubber can go bad, spreading the gooey and very sticky stuff all over immediately after being put to use. The tape was well beyond cleaning, fortunately there wasn't anything of interest on it.
Yes, same thing happened to me once. The Caliper drives in the A3070 seem to have less issues, but it did happen with a Archive Viper.
The tape is an immediate write-off, the gooey stuff makes the tape snap. Nasty stuff!
