We use the 3M tapes (DC-600HC) in 2 9144 drives and a 35401 autochanger.
We don't ever bother running mediainit and have no problems. I think this
is because the later models of HP drives (like ours) do auto sparing of bad
blocks on the fly. [I *know* that ours has a read while write head to check
for errors as it writes, unlike earlier tape drives.]
