Hardware: Asus U56E Upgrade from Xubuntu 13.10 64-bit to 14.04 64-bit I just upgraded to 14.04 and I also have this problem. During the upgrade, I received the above error multiple times. Here is an excerpt from /var/log/apt/term.log:
-------------------------------------------------------------------------------------------------------------------- Found memtest86+ image: /boot/memtest86+.bin ERROR: unsupported sector size 4096 on /dev/sdb. ERROR: unsupported sector size 4096 on /dev/sdb. ERROR: unsupported sector size 4096 on /dev/sdb. ERROR: unsupported sector size 4096 on /dev/sdb. ERROR: unsupported sector size 4096 on /dev/sdb. ERROR: unsupported sector size 4096 on /dev/sdb. ERROR: unsupported sector size 4096 on /dev/sdb. ERROR: unsupported sector size 4096 on /dev/sdb. grub-probe: error: unknown filesystem Found Windows Recovery Environment (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sda2 -------------------------------------------------------------------------------------------------------------------- /dev/sdb is an external USB-attached 3TB Seagate Backup Plus disk that has been attached to 13.10 since it was upgrade, and has caused no problems. The upgrade acted as though there were unrecoverable errors and that the upgrade would be backed out, but it continued and finished the upgrade to 14.04. There were a few minor configuration problems with the upgrade, but it appear to work properly. However, now, every time I reboot, I get a blank screen with the message: ERROR: unsupported sector size 4096 on /dev/sdb. Then the system hangs for about 30 seconds or so before continuing with the boot into xfce4. Once up, the Thunar file manager sees the Seagate disk and is able to mount and navigate it without problem. The Seagate disk is being used as formatted from the factory. gparted- pkexec/gnome-disks show an initial 8.0/8.4Mb unallocated partition followed by /dev/sdb1 with 2.73/3.0Tb NTFS filesystem and then another unallocated 4.46/4.7Mb partition. >From this information and the fact that this message is not logged in any system file, I would assume the the problem is with the grub loader. While this problem is investigated further, is there any way to stop the boot delay when this message is displayed? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1302762 Title: gpartedbin crashed with SIGSEGV in _int_free() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/parted/+bug/1302762/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
