Greetings from Philly,
Yesterday I got 1600+ errors when writing one TK50 tape with
my 780. Field Service agreed that the drive was ill and replaced it.
Today, with the new drive, I got 54 errors using BACKUP/NOVERIFY on
three tapes. ("Data sync not found - data sync timeout" according to
Vaxsim) Field Service says that 54 errors on three tapes is NORMAL.
Any suggestions or advice or confirmation?
Thanks,
--Bob Curley

The amount of errors will be different from tape to tape. We usally use BACKUP/VERIFY when we do backups and on the verify cycle it reports no differences between the disk and the tape. Also when we do restores from the TK50's we have no problem recovering the data (of course the amount of restores we do is small compared to the number of backups that we do). I kinda of agree that 1600+ errors on one TK50 is pretty steep.
