Noticed the speed increase when specifying '-e 100g' !
Yes!
And notice that even with hardware compression on, these drives can put
100 Gbyte on tape, thanks to the intelligent hwcompr algorithm that
somehow avoids compressing random data.
I think

Actually Gene, for this drive disabling hardware compression isn't
necessary. It's an LTO/Ultrium drive, and those are actually smart enough
to not compress already compressed data. Notice (below) how he still gets
the full 100GB native capacity? With those drives, you get the best of
both

Hi!
I'm trying to use amanda with HP Storageworks MSI5030 library.
It uses C7971A tpaes (100GB/200GB), but I can't find any amanda
tapetypes in th Net. So, I ran amtapetype. It was working for
about 12 hours with the folloeing results:
$ /usr/sbin/amtapetype -f /dev/nst0 -t HP-C7971A
