Have you tried the same five tapes on the other drive?  Are the errors at
consistant spots in the tape?  Are the tapes new or used?  Do you get any
errors during regular backup operations?  You said "it never seems to
happen" but have you grepped the logs to be sure?

I haven't had the need to clone anything in Legato yet...but i wouldn't
think the cloning operation would be a problem...it just reads one tape
while writing to another, right?

Oh, check the max error count for the drive too...is it incrementing?
That might explain why the drive is being disabled.

BTW, nice tape library.  Mine is a Dell version of the scalar 24. :)
