    HDD crashed, showing as Unknown Device


    Hello,

    My seagate 2TB internal HDD suddenly crashed after a couple of days of weird loading.


    The main problem I have is that the device is showing as Unknown Device on device manager. If i try to uninstall / Scan Hardware Changes, it just disappears. If I disable / enable, stays the same as unknown device. I reboot, and again it shows as Unknown Device but cannot do much. If I try to run any software to recover data, it won't see the drive so I cannot do it.

    Device Manager:

    DISK DRIVES
    SSD Drive (shows fine)
    Another HD I have (shows fine)
    UNKNOWN DEVICE

    Also if I go to disk management, it asks me to initialize the drive, which I dont want to do as I need the data that is inside.

    I hope someone can please help me, Id greatly appreciate it (you have no idea!)

    - I tried plugging it into a different PC, it didnt see it.
    - I tried swapping cables with the other HD, no difference.
    - Bios sometimes sees the drive, sometimes doesnt. Regardless of this, it behaves the same on Windows.

    Is there anyone with any ideas at all? I cannot believe I cannot find in google anything to help me in this situation. A data recovery service is quoting me 500 USD , seriously? For a HDD used LIGHTLY for 2 years!?

    Hi.
    Professional recovery services are expensive, yes.
    You could consider trying Spinrite.

    Thanks but spinrite did not work. At least it would stay in the looking for devices screen for 2 hours before i gave up.

    I was able to see the HDD now but it reads the sector so slowly it is ridiculous. I left it overnight and it didnt reach 1 million sectors out of 3.9 billion...

    Professional data recovery may be your only option at this point. They can even physically move the platters out of the drive and onto a new setup in a cleanroom, and try to recover your data that way. It's quite involved, and success depends on the failure mode. But, like I said, it gets expensive. Just depends on how valuable your data is. At one time, I was quoted $1,000 for a failed spinner which had irreplaceable photos, and even though I was ready and willing to pay, they still couldn't recover anything for me.

    it has valuable pictures, but also work documents that I had backed up at work but are confidential. If these docs leak, I can get in serious trouble. So it's a catch 22. I think I would pay the money if I could rest assured no documents would leak

    it has been such a nightmare this experience. I guess I was naive for not backing up data, I have had drives fail on me but never suddenly like this one. Usually I start seeing bad sectors, this one just died. I was able to "fix" the partition table with testdisk, and after reboot windows chkdsk started running and i stopped it (as this took 5 days last time). When I booted now my partition is damaged... I left it this morning running trying to recover the partition, it was going 1 cylinder at a time, out of 200k or so.

    Needless to say I hate seagate with a passion now

    Yeah, that one drive of mine that failed gave no warning either.
    I doubt you'd have to worry about your data being leaked from a reputable recovery company. They would go out of business pretty fast if they did that. You could ask for a web address of their T&C; I'm pretty sure they'll have you sign some sort of contract to have the drive recovery done/attempted, and a data privacy statement should be part of it.

    I'm not sure why Spinrite was taking so very long, but, have you tried contacting about it?

    I haven't, no.

    At the moment running photorec again, 2 million sectors in 1 day, 3905 million to go. I do hope it starts going faster later or i will need to wait 5 years for this to finish

    thanks for the reply, i appreciate it, but I tried EaseUS and it did not work for me. The problem I have is that it shows UNKNOWN DEVICE, not only uninitialized. If I am able to catch the HDD after a 100 reboots, then I just run photorec which is the only software that works for me.
