We have an internal drive and the report shows lots of TTE's, I have never
looked at this before so don't know if it has always been like this. The
report doesn't recommend replacing any media and we have not had any issues
restoring anything off tape.

Subject: Re: Temporary tape errors
I heard from my HW service provider this morning. They want to replace
the internal 5755 drive, a 'cage', and wiring harness I think that's it,
but he may have said something else. I asked whether the replacement drive
was tested and would eliminate the Temporary Tape Errors ("TTE" for short).
They said it was tested, but no, the TTEs would not be eliminated.
I asked why should I change drives and still have TTEs? They said this
drive would have fewer errors. They have 15 systems in their data center
and every internal tape drive has TTEs. Customers with internal tape
drives also have TTEs. Systems with external tape drives (data center and
customers) don't have TTEs. Per them, TTEs on internal tape drives is the
This *really* bothers me to think that it's acceptable in the midrange
world to have TTEs on internal tape drives. I'm really interested in
whether anyone on this list that is using internal tape drive for backup
would check their *VOLSTATS via the PRTERRLOG command and report.
I have yet to give them the OK to do this. When I do, I may say that I
want to do it Friday at 5pm so if there is a catastrophic issue we have the
weekend to recover. (The last time they replaced the internal tape drive
we lost a hard drive upon restart.) Maybe I'm overreacting, but I am
amazed at how much my confidence in the HW has been shaken over the past
couple of months.
