No. I would have recognized them if they had been such. These
smaller blocks are anywhere from 9K up to but not quite 16K.

I wouldn't have turned off the redundancy blocks - these tapes were
meant to be archival. I wrote them on brand-new, never-written 3M
Blackwatch tapes, at 1600 bpi, not 6250, in the hopes of more
longevity. If I hadn't been gallavanting around the world over the
past couple of years, I would have read these before, but here we are.
I know they aren't a total loss, and I _do_ still have the hard drive
these came from, but I figured I'd rather fiddle with tapes first and
an ancient Fuji Eagle second (especially since the Eagle hangs off of
an SI9900 attached to an 11/750 - something I haven't turned on since
the day Software Results closed.
Thanks for the confirmation.
P.S. - nobody asked, but I _did_ clean the heads and rollers between each tape.
