Just as a follow-up, I retensioned and read both tapes with clear bands this
morning, and they're fine. Since they were parked, there shouldn't have been
anything important there, and it looks like the removed oxide is staying on the

that I got a couple years

Fair enough.
If I had a process where something might fail in between uses, I'd
augment the process to re-write the image to a (new instance of) tape
before I try to use it.
Yeah,

Not archival storage, just day-to-day operation on old stuff, like Sun3/Sun4,

Ouch!
With my luck, that would have been the index / start of tape marker
rendering the rest of the tape mostly unusable.
That's after sitting parked a couple months.
Um I would naively think
As someone that has worked with computer tapes for nearly 40 years, I have to question the sanity of this. These
tapes are *HOW* old? What was their intended lifespan? While we all

That's after sitting parked a couple months. I have a Dysan doing it too. The
