    After hard reset, OS disk showing no volumes/partitions


    Hi everyone,

    I've searched high and low on Google for the specific issue that I'm having, but I can't seem to figure this out.

    About a year ago, I built my own computer. I have my OS (Windows 10) installed on a Plextor M6 256 SSD. Today, for about the fourth time in a year, my computer became unresponsive during normal use. After a forced hard reset, I was taken to a black screen with the 0xc00000e error, telling me that a required device was inaccessible. After a quick Google search, I found many answers saying that this problem was because of a corrupted boot record.

    I followed the steps recommended by Microsoft. First, I attempted automated startup recovery. This didn't work. Then I attempted to use bootrec to fix the problem. This resulted in the tool telling me that no Windows installations were detected.

    I decided then to open diskpart. The disk itself was detected, but whenever I listed volumes, nothing showed up for that disk. No partitions or volumes were listed.

    I've since recovered the drive by flashing a Clonezilla image that I had as a backup, so everything is up and running now. However, I am curious as to why this problem keeps happening. I've downloaded the diagnostic tools from Plextor for my disk, and it says that everything is fine. I've also run a Windows memory diagnostic, which has returned no errors.

    My assumption is that the hard reset is causing some kind of partition table corruption. But, that still leaves the issue of why the computer is freezing up to begin with unsolved. Any suggestions/possible causes to investigate would be much appreciated!

    Freezes are hard to resolve- there's usually no log entry related to the problem.

    What I suggest is
    a. test your hardware -stress test it.
    b. test your drive (Crystal Diskinfo (free) for starters, Macrorit Discscanner (free) for a surface scan

    Make sure your RAM is all the same type and meets your system specs.

    Do not overclock your PC.
    Check for any overheating.

    Use system defaults for your page file.

    Unfortunately your freezes are so infrequent, a process of elimination simply isn't feasible.

    You can do checks on your file system and Windows files
    From an admin command prompt
    [Windows key + X, click command prompt (admin)]
    chkdsk C: /F
    Your PC will need to restart.
    Make sure the result is clear or fixed- else do not proceed.
    Post back the result, which you can get after a restart as follows:
    How do I see the results of a CHKDSK that ran on boot? - Ask Leo!

    and from an admin command prompt run
    sfc /scannow

    Make sure your BIOS is up to date.

    Beyond that it could be drivers, installed software, some hardware incompatibility....

    To repair the boot problem you encounter, a Macrium Reflect boot medium has a useful tool. Also available on Kyhi's boot DVD/flash drive available from the top of the Software and Apps section here.

    What do you mean by the term "hard reset"?

    When was the last time you did a clean install of Windows 10?
