    Hi all,
    I had to format a Lacie Hd in FAT to transfer data from Mac to PC.
    In my Mac Pro, i've another Lacie Lacie with the same name. So I've initialized the wrong disk ... in ExFat (what is?).
    The initialization from Mac Journal to Fat is not successful .. told me that he could not finish it for some reason ..
    But no I can not read into the disk... He tells me that needs to be repaired but I cannot do it
    The Disk Utility says:
    Verify and Repair volume "disk2s3"
    Checking Checking file system volume.
    Checking main boot region.
    "Main boot region is invalid. Trying alternate boot region."
    Checking alternate boot region.
    "Alternate boot region is invalid"
    The volume could not be verified completely.
    Repairing the volume completed.
    Updating boot support partitions for the volume as required.
    "Error: Disk Utility can not repair the disk. Back up as many files as possible, reformat the disk and restore the files you backed up."

    What can I do?!!?!!?

    At the bottom of the Disk Utility Sx read:

    Point: Off Capacity: 1 TB (1.000.070.627.328 Bytes)
    Format: ExFAT
    Available: -
    Owners activated: -
    Space used: -

    Format A Hard Drive Using Disk Utility (which is in your /Applications/Utilities folder) Choose the appropriate format: HFS+ (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive) NTFS (Windows NT File System)
    • Read/Write NTFS from native Windows.
    • Read only NTFS from native Mac OS X [*]To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
      • For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion)
      • For 32-bit Mac OS X, install NTFS-3G for Mac OS X (free) (does not work in 64-bit mode)
      • For 64-bit Snow Leopard, read this: MacFUSE for 64-bit Snow Leopard
      • Some have reported problems using Tuxera (approx $36).
      • Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
    • AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    • Maximum file size: 16 TB
    • Maximum volume size: 256TB
    • You can use this format if you routinely share a drive with multiple Windows systems.
    exFAT (FAT64)
    • Supported in Mac OS X only in 10.6.5 or later.
    • Not all Windows versions support exFAT. See disadvantages.
    • exFAT (Extended File Allocation Table)
    • AirPort Extreme (802.11n) and Time Capsule do not support exFAT
    • Maximum file size: 16 EiB
    • Maximum volume size: 64 ZiB
    • You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.
    FAT32 (File Allocation Table)
    • Read/Write FAT32 from both native Windows and native Mac OS X. [*]Maximum file size: 4GB.
    • Maximum volume size: 2TB
    • You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.

    The simplest thing to do is to wipe the disk and restore from your last backup.

    You back up, right?

    If not, probably your only hope at this point is to buy specialized file recovery software or to pay for a recovery service.
