Then what do we use to determine if the tape and/or the drive needs work?
The > or the >> on the tape stats?

Anyone else know where these stats are?

Tape error stats on different types of drives can not be directly
compared.  Some drive types report very high temporary errors (QIC, 8mm),
but the error correction capabilities take care of that.  There was a
document I saw from IBM a few years ago listing what were acceptable
temporary error rates for different drive types, but I can't locate it
right now.

I used to think the 25gb tapes were great.  We had someone go from 45
minutes to do a SAVSYS to 4.  However, we are getting a load of write
errors.  On the brand new tape drive from yesterday, (after running a
cleaning tape through it six times).
Volume          ---Temporary Errors---   --------K Bytes--------
ID                    Read       Write         Read      Written
1FRI12                   0        9383           11     13895287

We don't seem to get any errors on our 3590's or 3581's.  Perhaps IBM
follows the philosophy of "Money talks - (expletive deleted) walks."

IBM is coming in again today to replace the drive.  And we will get them
here on a daily basis if need be until they get the (expletive deleted)
working.
