Be wary of upgrading the firmware on LTO drives.  See the thread last week
entitled "Re: LTO restore performance - seek problem?", there are some
major read performance problems in the last 3 releases of the LTO drive
firmware.

In the past two weeks i've gone from OBN1 to OCE1 to 12U7, and yesterday
to 1550.  And i'm still having problems.  I'd really like to go back to
OBN1 if i could find it...
