9710 STK SILO with Quantum Drives with DLT tapes
Library at microcode level 70
Fast drive load option enabled.

When I receive an I/O error on a tape drive the process hangs.  I can't get
the process canceled which is currently running.  After many hours the
process finally releases the tape drive and I can access the drive again.
Any suggestions for what I can try would be appreciated.
