It's not really a linux utility problem, nor a gnome-disk-utility problem. Whatever is identifying devices is making a mistake.

GNU parted shows nothing on this disk: GNU Parted 3.2 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Error: /dev/sda: unrecognised disk label Model: ATA WDC WD2002FAEX-0 (scsi) Disk /dev/sda: 2000GB Sector size (logical/physical): 512B/512B Partition Table: unknown Disk Flags: but when I check with `lsblk`, I see one disk with partitions and the other without: Code: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 1.8T 0 disk └─sda2 8:2 0 1.6T 0 part NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdb 8:16 0 1.8T 0 disk and the Disks utility agrees (see: http://ibin.co/2SQv4KbH06Mz). Also, /dev/disk/by-id contains an entry pointing to sda and one pointing to sda2. So it really does think there's a second partition there. Thinking there was something wrong, I re-filled the disks with random data. Now sda is properly (in the Disks utility as just an "unknown disk"), but sdb shows a second partition, and identically to how sda was showing it before (ie the Disks utility output is the same with 181GB at the beginning and 128GB at the end). I am running all this from the Ubuntu Gnome 15.10 installer disk.
