Title:
  GParted destroyed my partition table: "Invalid partition table on
  /dev/sda -- wrong signature 0."

Status in “gparted” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: gparted

  I used to have the following partition table:

  ext3 /dev/sda1     (mounted at /)
  extended
    - swap /dev/sda5
    - ext3 /dev/sda6     (mounted at /home)

  The /dev/sda1 was too small for me though, so to increase it I used
  GParted on a Jaunty LiveCD to queue the following:

  - Shrink /dev/sda6 to half size, creating space on the left.
  - Move swap to the right.
  - Shrink extended to fit, creating space on the left.
  - Grow /dev/sda1 to fill.

  GParted successfully did step 1, but at the end of step 2 it had a
  fatal error:

  Invalid partition table on /dev/sda -- wrong signature 0.

  After closing the dialog, the entire partition table is now gone -- it
  all shows as "unallocated space".

  GParted's saved report is attached.
