Some maybe. I have a 1Gb seacrate hawk I use on a TRS-80 Color Computer
that is a good 15 years old, and I hooked up an old Quantum P40S beside it
the other day that must be close to 18 years old. No bad sectors were
found when I did a logical verify of the surface.

That seems to be a recipe for disaster. Will there be a working tape drive
to read those old tapes in even 40 years? Here, I use 4 1Tb drives as
individual drives, 3 of which have individual installs on them, and the 4th
is for amanda, doing nightly backups of whatever install I am running this
year. With smartd running, I have been told far enough in advance of an
impending drive failure that my email corpus has not been lost since early
2002.

So have I observed. Twice that I know of at my former, and occasionally
still, employers.
