This problem sounds suspiciously like the following upstream bug report: Bug #623630 - Move logical partition to right yields invalid partition table on /dev/sda -- wrong signature 0 https://bugzilla.gnome.org/show_bug.cgi?id=623630
In the upstream bug report, the Extended Boot Record was overwritten when the partition was moved and this caused the invalid partition table. The upstream bug was fixed with GParted version 0.6.2. ** Bug watch added: GNOME Bug Tracker #623630 https://bugzilla.gnome.org/show_bug.cgi?id=623630 -- GParted destroyed my partition table: "Invalid partition table on /dev/sda -- wrong signature 0." https://bugs.launchpad.net/bugs/434463 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
