2007-01-17 08:30:33
Hi All,
I forgot to forward the tapetype definition I got for
my HP Ultrium 960, after disabling the hardware
compression.
The tapetype definition is as given below:
define tapetype unknown-tapetype {
comment "just produced by tapetype prog (hardware
compression off)"
length 386048 mbytes
filemark 0 kbytes
speed 67629 kps
}
Thanks for the help
