[comp.sys.mips] Cartridge tape

bin@primate.wisc.edu (Brain in Neutral) (02/07/90)

Hardware: M/120 with Q-120 cartridge tape drive.

Occasionally while doing backups (dump.ffs) I see error messages such as
the following:

	Feb  6 10:36:27 uakari unix: SCSI 6L0: Non-recoverable data error

What exactly does this mean?  That the driver has found a bad spot on the
tape and has skipped it?  I notice that if this occurs a single time, the
dump proceeds, but that if it occurs 5 times, e.g., 

	Feb  6 10:36:27 uakari unix: SCSI 6L0: Non-recoverable data error
	Feb  6 10:36:28 uakari last message repeated 4 times

then dump.ffs asks whether I want to restart.

If the message occurs once and dump keeps going, should I be concerned,
or is this a normal occurrance?  (Pardon my hopeless ignorance; I'm not
experienced with this type of media.)
