[Bug 945433] Re: gparted crashes on scanning GPT formatted drive

[Ahmad Moawya]

Here are my findings thus far:

1- Ubuntu does not detect any partitions during boot. (don't see them in
the file manager)

2-  Checking the system log, I get "unknown partition map" or something
similar to this.

3- Gparted (and parted-server when I run the installer) crash.
Runnung parted thru terminal, I get "Assertion (last_usable <= disk->dev->length) at ../../../libparted/labels/gpt.c:718 in function _parse_header() failed."

I verified my disk using GPT fdisk (gdisk) and verification was successful (found valid GPT and protective MBR)
Mac OS X disk utility verification finds no problems whatsoever.
Interestingly, I tried an Ubuntu 10.04 live CD I had and it detected the partition, Gparted works fine, partition are listed in nautilus, and I can mount them.

I suspect this issue is either related to parted binary or the newer
linux kernel.

Feel free if you have any questions.

Title:
  gparted crashes on scanning GPT formatted drive

Status in “gparted” package in Ubuntu:
  Expired

Bug description:
  Gparted (0.11.0-1) crashes whilst scanning drives when opened
  normally. I opened up terminal and specified each device in turn - it
  can scan - and indeed work normally with - all of my drives (2
  external, 1 internal, all NTFS formatted) bar one (internal) which has
  a Guided Partition Table rather than MBR, and two partitions: HFS+ and
  NTFS.

  Running gparted from a 12.04 beta Live CD. I ran it earlier from
  within Parted Magic and it worked just fine. I'll check the version
  used by that Live CD later and report back.
