It is my understanding that this drive was delivered with HW compression
enabled. I have done nothing to disable it.
After visiting their web site I see the problem...
The tape is a V17. I did not recall, so I simply assumed that when you
mentioned the V10, that it must have been the correct number.
The definition should then read:
define tapetype V17 {
comment "V17 in ECRIX Model: VXA-1 Rev: 2959 w/HW compression"
length 55000 mbytes
filemark 1931 kbytes
speed 2024 kps
}
Given this, Ecrix significantly overstates their capacity. For the V17,
they advertise 33G uncompressed and I got 27.5G. That's almost 17%
overstated.
Is this common in the industry or is Ecrix out on a limb?
Or am I misunderstanding the meaning of the numbers reported by
tapetype?

Are you saying the drive does not stream with HW compression? How does
one know when the drive is streaming and when it isn't?
Thanks,
