[Bug 945433] Re: Incorrect GPT length should be handled better

[Oliver Joos]

I see this crash with an external USB disk with MBR only (no GPT!)

I tried to shrink a FAT32 partition with gparted when the crash occurred
the first time. Now the partition still has its old size, but the FAT32
filesystem has the new, lower size. Fortunately no data was lost.

IMO the importance of this bug is not low.

Title:
  Incorrect GPT length should be handled better

Status in gdisk package in Ubuntu:
  Confirmed
Status in parted package in Ubuntu:
  Triaged

Bug description:
  The GPT LastUsableLba claims the disk is longer than it actually is.
  Parted should handle this error more gracefully and allow for
  repairing it.  gdisk seems to let the error go undetected, possibly
  because it is using the size in the protective MBR rather than
  LastUsableLba.
