 Bingo on the firmware, I think.  We had a miserable time with it--
 long blocks being one of the biggest issues. 
Well all was not lost as it turns out - that first tape only contained 160MB
of data out of a possible x GB, so it's finished! I'm not getting anything out
of the other tape though - I can't even drag any raw data off it using dd,
which I would have thought should be possible. Either the tape's broken or the
drive just plain doesn't like it for some reason (this is the proper data
cartridge too - it was the backup to video tape that's read successfully)
  You might want to find someone with an 8510 with a
later firmware rev
 and see if you can use that--or just try the generic Exabyte 8500
 firmware and forget about TTi's little board. 
Yep....
It looks like TTi went to a lot of trouble / expense to turn a reliable drive
into an unreliable one, all for the sake of a bit of front-panel status info :-(
