Hello Emanuel
I am using this device, its an Ultrium 5 (LTO5)
Its an older changer and I am unable to update the firmware, still working on that.
What version of mt are you using, as I am testing using a RHEL7.2 base and the upstream patched kernel.

This is what I get when I try and partition and I believe this may be a firmware issue for me.

What is the type of drive exactly? I still couldn't test with the LTO-5
drive as the machine it's connected to is being reinstalled.
