Um .... I would naively think that would invalidate any test / concern
unless it was specifically for the problem that you're describing.

Is that belt or tape media? I (mis)took it to be tape media.

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.

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
