    Hard Drive seems corrupt. 1 Partition now showing now as 2 Partitions?


    Hello

    Short story. Western Digital Elements Drive 3TB use for back up and today wouldn't power.
    Swapped all cables no luck.
    Removed hard drive from Caddy housing and mounted in rig direct to motherboard.
    The hard drive is readable but appears something has happened to the partition (without me doing any tasks etc to it).
    The hard drive was 1 single partition with quite a lot of data.
    The drive now in the rig is showing as 3 partitions (raw data). This is now showing as 2 partitions since loading in system rig and converting from MBR to GPT. Snapshot below.
    I have not reformatted the drive and the drive is showing as inaccessible in windows.
    (I have just ordered another 3TB drive to try to recover the data too.)

    Questions:

    1 - Any ideas what would cause this issue with the partitions as has baffled me and made me more cautious in recovery routes and options.
    2 - Before I try Recuva on the drive (which I assume I will need to format the drive first to attempt this). What is the best steps to take before attempting to recover the data.
    3 - Any other software that is going to do a better job than Recuva?
    4 - Anything else to try before I do down route 2.

    Thanks for your help. Normally I have back ups. But there's a large chunk of photos and other data I had yet to back up to my secondary back up drive

    Thanks for your help

    The drive causing the issue is Disk 1.
    I am aware that W drive is overloaded at this moment. I normally maintain 20% headroom.
    Drive G is being removed (hence back up data on W and new hard drive on its way)

    Hi mfx

    Likely the faulty hard drive caddy. See @clam1952 in thread below.
    @spunk has suggested other software that you may want to investigate. Ignore my post in that thread. (Same thread below)

    May be @SOHO1 can post what software he used to fix.

    What is a RAW drive and how do I fix it?

    Thanks for the response.
    Going to buy minitools (be useful for a few other drives maybe Ive got stored for a rainy day).
    The hard drive is out of the caddy. Popped it in an external usb2 caddy and wouldn't see it.
    Installed in rig and well screenshots show the results.
    Will let you know how the minitools works out.
    Thanks again.

    I've been advised by minitools to convert the corrupt disk 1 to GPT from MBR and then used data recovery, will this cause any additional damage/problems? Disk 2 (2.73TB) is the hard drive I am trying to recover.

    Email below (there response in italics) after sending a minidump as it wasnt scanning the hardrive as noted at 12%.

    Disk 1 is MBR disk, please convert it to GPT with MiniTool Partition Wizard”

    The disk has not been altered to MBR this is the format when removed from the caddy and when loaded into the rig directly on a sata cable to the mortherboard, it showed as 3 partitions which has now changed to 2?

    “Besides, you can recover data from RAW partition with MiniTool Power Data Recovery”

    Does this mean the the MBR to GPT conversion is not detrimental to the data on the drive?

    Note: Before data recovery, please stop doing any operation to your partition. Otherwise, the possibility of data recovery is slim.”

    By this you mean it is okay to convert from MBR to GPT and then attempt data recovery?

    Hi mfx,

    Hold on for some more time. Do not do anything.

    Your 3TB Elements drive is most probably an advance formatted 4096 Bytes per sector size MBR drive. The electronics ( SATA to USB bridge) inside the enclosure has a special drive Translation circuitry that converts the data stream from 4096 sectors to 512 Bytes data stream and presents it to the OS. If you take it out of the enclosure that drive translation is lost.

    If you want to recover the data the right course would be to use TestDisk, check what sector size is shown and if it is 512 bytes change it to 4096 bytes per sector and ask it to read the data.

    You will only be mucking up the drive by converting it to GPT.

    Please check the external enclosure case and let me know whether it carries the AF Logo.

    Hi

    No AF logo. Its a WD Elements drive. The problem is the drive was not powering or booting from the caddy. Unfortuantely in relation to your post Im too late. The drive is mounted in the system.
    Converted to GPT from MBR.
    It's requesting to format and then use Recuvva to get back the data?
    I have not formatted yet.

    Do not format. Why were you in such a hurry? You asked a question "Does this mean the the MBR to GPT conversion is not detrimental to the data on the drive?" and even before any one could answer went ahead converting it into GPT.

    That definitely is not going to solve your data recovery problem since as I said it is the sector size problem that makes your drive unreadable on direct connection.

    Yes sorry if I was not clear. I emailed to the minitools developer. He stated it needs to be converted to GPT as the data wont recall. You are quite correct.
    Im holding fast until I know what to do next.

    Thanks my apologies.
