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

Yogesh
