Are the DDS drives on both of your systems identical?  It sounds as if the
937's drive may not be a DDS-2 or DDS-3 drive, thus the inability to read
120-meter tapes or read compressed formats.  I believe this was true of the
DDS/DDS-1 format drives, but I might be mistaken.

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.
