We have two HP3000 computers.  One of them is a 939KS; the other is a 937RX.
We have the same version of Roadrunner on both machines.  I have experienced
times when the 937 could not restore a tape written on the 939, but could
restore tapes written to its DAT.

If the tape from the 939 is a 120 meter tape the 937 cannot read it.

If we haven't issued the command DEVCTRL 7 COMPRESSION=DISABLE the 937 cannot
read tapes from the 939.
