Windows 10: Home Power Failure and Disappearing HDD

    Home Power Failure and Disappearing HDD

    Hi guys,
    I was lucky enough to have a power cut a couple of hours ago, and despite the PC being on a surge plug it seems to have broken one of my internal harddrives.

    I've never had a problem with it til now, but I tried to find it in my computer to no avail, however when I go to Disk Management I'm told I need to Initialise Disk.

    Since I'm aware this would cause me to format it, does anyone by any chance have any alternative ideas I can try to attempt to get it back to it's previous state?

    Many thanks in advance!

    1. Please post a screenshot of Windows Disk Management.

    2. Download, install and run MiniTool Partition Wizard Free Edition v 9.1 (30.49 MB ) from from Free download Magic Partition Manager Software, partition magic alternative, free partition magic, partition magic Windows 7 and server partition software - Partition Wizard Online

    3. Post the first screenshot showing your drives - the first scree that appears as soon as you launch Partition Wizard.

    4. Launch PartitionWizard, on the left Pane click on Partition Recovery Wizard > Next > Select your problem drive > Next > Full Disk > Next > Quick Scan > Next. Allow the quick scan to complete. At the end of the quick scan you will get a window showing all the found partitions. Post a screenshot of it. After you have taken the screenshot click on Cancel button on that Window and close PW. You can run it again after getting further instructions from me.

    Hi there,
    Thank you very much for your response, I have attached the requested screenshots. I wasn't able to get the drive to show up on the Partition Recovery Wizard within MiniTool Partition Wizard, sadly. If it makes any difference at all, it was my D: that failed.

    Please remove all external drives and Flash drives from your PC when we troubleshoot this problem. This will avoid any confusion and accidents.

    After removing all external storage devices from your PC, check how your internal drives show up in Device Manager. Post a screenshot. Check the Properties of the problem drive.

    Furnish complete details of your problem drive. Manufacturer, Model Number . capacity. You may need to check the health of your drive with the manufacturer's utility.

    Also let me know how many partitions you had in that drive and also whether it was initialised as an MBR drive or GPT drive.

    Unfortunately the surge protector doesn't prevent problems with power failures, for that one needs a UPS/Uninterruptible Power Supply or also known as a battery backup. The UPS maintains several minutes power to the computer so as to allow an orderly save of open files and normal shutdown. A surge protector is supposed to prevent excess or unwanted power surging/spikes which can damage equipment.
