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 that would invalidate any test / concern
unless it was specifically for the problem that you're describing.
I have a Dysan doing it too. The Dysan had been re-banded with a boiled
3M band and run for years like that with no shedding.
Is that belt or tape media? I (mis)took it to be tape media.
I have another Dysan with a green Plastiband in it which is also fine,
minimal/no shed. So, I think we may need to re-evaluate if the clear
Amazon cheap "plastibands" are perhaps totally incompatible with tape.
My naive understanding was that they were Good Enough™ to get data off
of the tape as in one (or a few) last hurrah(s) for data recovery.
(Comparing multiple reads.)
I know, I know..."just use the band to get data off." But I want to
*run* QICs without having to destroy them constantly.
I wince at the idea of running with QIC tape. But my experience is with
QIC-80 tapes of the '90s which were so unreliable as to be in the same
category as AOL floppy disks during the late '90s around the transition
to CD-ROMs. As in I would trust an AOL floppy disk to better hold my
data for a week than I would a QIC-80 tape to hold data for a month,
much less a year. ...and I didn't even trust an AOL floppy to go from
computer to computer for 5 minutes. -- Talk about a race to the bottom
for quality.
