Has anyone had trouble with firmware & HP Ultirum 3 drives under windows?

We have two HP LTO3 960's (I believe, no-one is certain and I'm doing this
all remotely....) on an Adaptec ultra320 SCSI card, in a quantum M1500
library consisting of two stacks.

We are currently seeing intermittent read/write errors on all drives
connected to a scsi card at the same time, but only during reclamation.
migration / stgpool backup go fine. I havent tested move data yet.

The sense data and description seem to fit this problem for Sony AIT
drives;  http://www-1.ibm.com/support/docview.wss?uid=swg21207591

But on downloading firmware from HP for LTO3 drives, replacing TSM drivers
with HP lto drivers so the HP Library and TapeTools can upgrade the
firmware, the firmware upgrade fails stating 'The firmware is for the
wrong personality of drive' or similar.

.. I am chasing up that these drives are actually what people claim
although this seems to be info lost to the ether. All I can see is
'Hewlett packard LTO Ultrium 3 drive' under windows - no differentaition
as to wether 960 / 920 or an OEM version. Still, there is no firmware
available I can find for the 920's, only the 960's. Any help on how to
determine exactly what drives they are under windows would help :)



Thanks,

Matt.
