Wanted to select this disk but had the following error:

We are not supporting this label right now. Shouldn't we support this?

This most likely indicates that the disk is (or was) used by something like LVM or btrfs.

@matthiasdeblock can you shed some light on the environment where you saw this (ping me on skype about it.)

I see this on IITB atm. I build a software raid 5 with 3 disks and the partition table was loop. Not sure if this is something from mdadm or not...
