Re: problems with tape drive?
2002-09-03 03:27:30
Hi,
your problem is the fixed hardware-blocksize of the SDT-10000,
i had the same problem with my SDT-9000 and solve it by switching
it to variable blocksize using
mt setblk 0
after each reset as the tapedevice switches back to the fixed default
block-size after every reset.

Hi all,
I'm having some grief with a tape drive that starts backing up, but gets an

Some dumps may have been left in the holding disk.
Run amflush to flush them to tape.
