Title:
  Removable storage device Master File Table wiped whenever I connect it

Status in “udev” package in Ubuntu:
  New

Bug description:
  Whenever I connect my external harddrive to my laptop Precise 12.04
  64bit it seems to recognize it very slowly. I then access the drive do
  what I have to and safely remove. I then plug the same drive back in,
  Precise does not mount it and when I go to palmipst(drive utility) the
  drive is there in the left side menu but it says "unknown" and the MFT
  is completley wiped from the drive. I then try to format it again and
  it gives me this error: "Error creating file system: helper exited
  with exit code 1: cannot mount /dev/sdc1 at /var/run/udisks/job-mkfs-
  YNuk7p: Invalid argument"

  Filesystem label=Music1
  OS type: Linux
  Block size=4096 (log=2)
  Fragment size=4096 (log=2)
  Stride=0 blocks, Stripe width=0 blocks
  7331840 inodes, 29304832 blocks
  1465241 blocks (5.00%) reserved for the super user
  First data block=0
  Maximum filesystem blocks=4294967296
  895 block groups

  (I forgot to mention, when I plug the drive in I do a check file
  system thru the Drive Utility and it states the filesystem is "Not
  Clean") then my MFT dissapeers.

  This happens with any file system I try except when I try FAT, it just
  fails to format it without throwing up an error. I thought it was the
  enclosure the drive was in so I purchased a new one and it does the
  same thing. To be more clear, I have two external drives with the same
  exact enclosures one 500gig and the other is 120gig. The 500gig has no
  issues when plugged in, the 120gig tries to format and access the
  drive(I can see this by the flashing light on the enclosure) but fails
  with the above error.

  I then boot into a live cd of Precise 12.04 and the exact same thing
  occurs with the same errors. After leaving the live cd Precise I boot
  into sysrescuecd and go to gparted, it of course complains that there
  is errors on the drive and no MFT. I create the MFT again, then format
  it with any file system and all is just fine with this drive. After
  this its back to my normal system Precise 12.04, plug the drive in and
  instantly the MFT dissapears again. So to further check into this I
  made a live cd of the Maverick 10.10 64bit, booted into it and go to
  gparted, of course it complains there are errors and no MFT, create
  the MFT, format the drive and all is fine, file system check says
  "File system is Clean", I can copy music or whatever from my main
  Precise 12.04 /home 1Terabyte drive to this drive and it works just
  fine. I also plug the 500gig external + another 500gig external
  powered drive in at the same time with the 120gig and I can transfer
  music and whatnot between all drives with no issues whatsoever. All of
  this is being done from the live cd Maverick 10.10. After transferring
  50 or so gigs of music to the drive working from the live cd I do a
  filesystem check and it says "Filesystem is Clean", I boot back to the
  main system, plug the drive in and the same scenerio occurs, "sees the
  drive", "filesystem Not Clean" "MFT dissapeers" "try to format it and
  the above error is thrown up"

  I am not an expert in Linux and the above error means nothing to me.
  Please tell me I can fix this somehow. I personally think this is a
  serious problem. I had tried to use this drive as a backup drive for
  some of my music and in fact had it full of backed up music, then this
  issue happened and wiped the MFT and all the data, even Testdisk sees
  the drive as having nothing on it. Luckily this was a backup and I
  didn't lose any of my precious music but it could have been a serious
  loss of data. I think this probably started after an update of some
  sort but I can't be certain.

  Please let me know in non-expert terms if I can help further with this
  issue, or in fact if I am missing something obvious here.

  Thank you and sorry for the long report, but its the only way I could
  explain it all.

  Cheers,

  Singtoh
