    HDD became slow and dissapeared


    I have windows 8.1 and 2 HDD's. One of them, which has 1TB became slow a few days ago, and also getting some I/o errors when trying to access data stored on it.
    This morning, when I booted my pc, when the windows logo appeared it started to scan for drive errors.
    I opened File explorer and discovered that the two partitions I had on this HDD are missing.
    So, I looked into disk management and it says that I must initialize that disk with GUID or MBR before Local Disk MAnagement can access it and also that this HDD is "Unallocated"??? Don't tell me I lost this data...

    Any advice would be appreciated. Also, could I recover those files.
    Thank you in advance

    It sounds for me like the HDD has failed.
    You could get the data back by going to a specialist for this, or try to plug the HDD into another pc.
    However, there is an equipment (don't know anymore what it is called) that some specialists use to recover data from a failed hard drive.

    Using commercial companies to recover data from failed drives is very expensive. I had a Seagate suddenly crash on me last year and I couldn't get price quotes lower than $1000 USD to do recoveries from it. So, unless you're willing to spend a LOT of money, commercial services are not the answer.

    You could try using a Windows data recovery tool. These can read drives that are not formatted because they don't use the partition tables to find files and folders. Best one I've used recently is Active@File Recovery Pro. You can download and try it for free -- but to get good use out of it, you need to purchase a license. Last time I checked, their licenses were around $30 USD.
