Title:
  hot swap gpt hdd destroys partion table during swaping

Status in The Linux Mint Distribution:
  New
Status in Fedora:
  New

Bug description:
  Hallo,

  I have a Asrock Z77 Pro4-m Board and a Seagate 3tb ST3000DM00-1CH166
  with Firmware cc24.

  with Ubutnu 12.10 64bit also tested it with fedora 18 beta

  A Bios update did have I done. So the version is currently on 1.70.
  The HDD Bios  I cant update because there is no newer version.

  The Hdd is connect to sata.

  The HDD i have formated via gparted as primary partion with ext4 and
  gpt as partition table. Alignment  was set to optimal.

  The Problem occurs if hot unplug(with umount) the disk and try to hot
  replug(with mount) it.  Then the partition table isnt recognized and
  gdisk shows me:

  MBR: projective
  GPT: damaged

  In the case I can always start the system via Paragon Live Image which
  repairs me automatically the gpt header so that I have not to repair
  it inside the tool. After restarting Ubuntu I can mount the drive
  again.

  In the case where the partition is damaged, the partion is the most of
  time recogonized but the filesystem is unknown. But not everytime.

  The same occurs with the mainline kernel not only with the shipped
  kernel.

  Smartvalues are ok.

  I also changed the sata port,chipset and cable but the problem occurs
  further.

  In the bios all controllers are set to AHCI.

  Here some dmesg output:
