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

[Ahmad Moawya]

According to OS X, the number of sectors is 312579695 in both diskutil (GPT) and fdisk (protective MBR), 
So, although the actual GPT contains the larger size, OS X diskutil respects the HPA and lists the smaller size. 


So if I understood correctly, the problem here is that linux is not respecting the HPA and therefore confusing partitioning apps with 2 different sector numbers for the same disk?! Kernel issue?

Title:
  Incorrect GPT length should be handled better

Status in “gdisk” package in Ubuntu:
  New
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.
