Bug Description
I have two 2T disks with no partition table and which have been filled with random data. 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://
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.

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