    Unable to use MBR drive on Windows 11


    Howdy! some one gave me a 16TB external drive. I'm trying to use it with Win11 as a back up drive, but no machine can mount the drive. I'm unable to partition, format etc. It shows as Disk 1 partition one when I plug it into a lap top but nothing else can be done it has no drive letter assigned, right clicking in disk management shows grayed out and fdisk can't access it either.I've tried on windows 11 via a HP and Toshiba. Both update can't find driver updates. Any suggestions? Thanks!

    :)

    MBR keeps corrupting after restart

    I have a machine that when restarted or allowed to go into hibernation, I receive a missing/corrupted master boot record message and Windows doesn't boot. I am able to successfully repair the MBR each time using Windows recovery console, but I'm unable to determine what keeps making it happen.

    Dell Latitude E6420
    Windows 7 64bit

    Steps performed so far: -besides fixing the MBR after each restart or hibernation
    -ran system file checker sfc /scannow
    -ran chkdsk
    -verified that ACHI was enabled in the bios

    If I can't figure this out I will end up just reinstalling the operating system, but I worried that the issue with just reoccur later down the line. Any advice/recommendations would be much appreciated.

    Unable to use MBR drive on Windows 11

    Anyway to transfer MBR to data drive?

    There are plenty of mbr backup tools. You can of course write it back to another drive. Just Google for MBR backup. Though I'm not sure if it would actually work. ie the mbr will probably point at disk2 or something, so it wouldn't work when the Windows disk becomes disk 2.

    Try using the recovery console, ie fixboot and/or fixmbr.
