    There is no point in running GetDataBack for NTFS and FAT. Either you had NTFS filesystem or FAT filesystem.
    Try also TestDisk (TestDisk - CGSecurity). I remember few years ago that this tool worked better for me than GetDataBack.

    Maybe you partition table somehow got erased, it happened to me few days ago...
    Try to restore partition table with TestDisk, it workd fine for me.

    The last thing I can think of are bad sectors, for that try running HDD Regenerator.

    Remember WinHex? It could also help here.

    Just remember rule no. 0 of data recovery - don't write anything to the disk you want to recover from.

    it could be problem with the files system. try this tool Partition Find and Mount — free partition recovery software. it helped me once in recovering files from usb flash. it should find the partition on the hard drive, mount it as a new drive and you could make backup of the files.
    after that format the drive and restore the files.

    I'm flattered. Thanks for the confidence.

    Well, it could be anything but most frequently is a thing called overlapping. One partition exceeds its borders, coming into another partition which comes into another and so on, breaking the table.
    Now, for the partition table to be 'validated' the bios checks for a specific number of bytes at the end of the MBR. Those are 55 AA.
    You could use any hex program to load the entire contents of the disk and search for the above at the end of sector 0 (MBR is stored only there).

    Code:
    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
    00 00 00 00 00 00 00 00 00 00 00 00 00 00 55 AA
    This is the end of the mbr. If it's not there then that's one of the possibilities.

    Your partition entry (1st) will start at 1be meaning byte 446 (the start of the partition table). Meaning row 1b0 in column 0E. It will be easy to stop as this will start with number "80" for bootable.

    Mine looks like this
    Code:
    80 2D 18 00 07 88
    Check these and see if they exist. If not, will try to remake them.

    If you prefer an alternative approach you could try TestDisk with these options:
    Expert mode: Yes
    Cylinder boundary : No
    Allow partial last cylinder : Yes

    And I would advise you make a raw copy of that disk BEFORE USING ANYTHING ELSE using a program like CloneZilla (bootable linux live cd). It will clone as-is so that if you make a mistake you can restore the original.

    first of all try mounting the device using a ubuntu live cdor another linux. usually this will give you access to your files. if this doesn't work, try the above tips :)

    where would i make back up of 1.3 tb ..
    will collect money ..will take a month or two.. i spend everything last in last 2 weeks ..i went up in mountains on tour with friends
    clonezilla will make back up right?
    what's up with linuxboot live cd?u mean i should install ubuntu n then try plugging the hdd?

    and test disk will fix my filesystem without messing my data?

    m scared for my pics n music videos man... 700 gb of music videos dammit

    It's very simple. In your image you have:
    1. boot indicator (0D)
    2. beginning head, sector and cylinder (0A,42,4F)
    3. system indicator (which is the filesystem) (4F)
    4. ending head, cilinder and sector (54,4D,47)
    5. starting sector (52,20,69,73)
    6. size of partition (20,63,6F,6D)

    In the parentheses you have your values.

    In red I marked possible errors as folows:

    1. boot indicator is the byte that tells the bios if the partition is active or not. To be a valid partition it should contain 80 (for active) or 00 (for a non-os partition. example: for data storage)
    2. system indicator is the filesystem type. If you would of had NTFS it should of been 07. As you can see in the partition types

    Strange that the filesystem ID is a duplicate of the last value.
    Probably this was done by a program or by some HDD errors. Could be a bad block that was swapped with a fresh block but the data on it was lost. Thus the duplicate appeared. Just a theory...

    My guess is that if you'll change the system indicator from 4F to 07 it will work as usual.

    what's up with linuxboot live cd?u mean i should install ubuntu n then try plugging the hdd?
    No. I meant CloneZilla is a linux based live cd. It will make a backup of your partition AS-IS (including any problems on it).

    for some reason its just showing me only the hex codes nothing else
    It's a hex editor. Should it show anything else than hex values?

    and test disk will fix my filesystem without messing my data?
    TestDisk does exactly the same thing we're doing manually: correcting the mbr by editing its hex values. No one can guarantee that a program, any program will work without any consequences. That is why the standard answer always is: BACKUP YOUR DATA FIRST.
    Everything is based on trial and error. Even for the smartest IT pro alive.

    Yes. High probability your data is safe and sound.
    Your HDD is not failing so there's no reason to replace it (if that's your intention).

    thnk god.. i got scared coz getback for ntfs failed.. it showed 3 gb data only
    my intension is just to recover data not to replace it .. i don't even care about the drive seriously... i'm getting new drive to back up raw data via clonezilla

    i think u demanded this right

    Thanks for screenshot but it is not complete. For future reference, it should end with a line (similar to your first screenshot). The lines indicates the end of the sector.
    1. Open Disk - Physical Media - Drive x
    2. Edit -> Copy Sector -> Editor Display

    Paste the data here.

    Off topic: what is it with you guys and external drives? They seem to fail for no reason...

    If you haven't backed up the drive folow below:
    Download Parted Magic

    Run: Go to: Extras Menu -> Clonezilla
    Select:

    Device-to-Image ->
    local-dev -> *See if you can locate your usb drive here. If not, go back and select usb.
    select the drive to hold the result ->
    select the folder to hold the image ->
    select Expert ->
    select savedisk ->
    select ntfsclone > partimage ->
    select -c -j2 -ntfs-ok
    select -z0 for the fastest backup
    confirm choice (entr y) ->

    The entire procedure will take 2 ~ 3 hours if we don't use compression at all. Maybe more. depends on the speed of the drive and how filled is it.
