yeah, looks like it should fit.  There are the tape headers
and file marks to consider, but that shouldn't take a big
piece of the nearly 1GB you seem to have available.

I'm pretty sure a simple rm -r would suffice.

Couple of other things you might consider/do.

If holding disk (HD) space is not a problem, leave them for
a while.  Recovery/restore if needed can be done from HD.

Run amcleanup after the rm -r.
Don't think it will do anything, but it also won't hurt anything.

You probably "wasted" a tape or three doing failed amflush's.
Get them back in cycle by amrmtape and amlabel -f <same_label>.
Of course, if confident, you can hand edit the tapelist.
