    fix Disk Unknown Not Initialized m-2 drive without any data loss


    I have a very stressful and ongoing problem I'd like help with, please.


    About a week ago, my acer swift 3 was working fine windows 10. One evening it was slow, so i restarted it. it worked fine after this, i watched an episode of a show online, and then closed the laptop and went to bed. The next day I opened my laptop to use it, and the device would't boot. it spent 2 days with the acer screen, and the loading wheel. I tried booting and pressing F2, then selecting save and exit, as advised on the acer forum. This did nothing but change the issue to a 'no bootable device' error.


    I bought a windows recovery USB to boot from, and tried to go down the 'repair your computer' route, but this did not work, as my drive was not being recognised, and no restore points had been created that i could access


    I eventually bought an m-2 enclosure, opened up the laptop and removed the m-2 drive. I installed the drive into the enclosure, and connected it to another PC, however the drive did not show up. After some searching online, I used disk management, and only then can i see the drive. At first it asked me to initialise the drive, which i selected yes to without much thought but then I got an error, something along the lines of 'could not initialise die to fatal error'. So, the drive is not initialised. I now know this is good, since that would have wiped it.


    After some more research, it seems the issue could be that I need to fix the MBR. However, I don't know if this would delete my data, and safe data recovery here is paramount.


    At the moment, the drive in disk management is showing as:


    Disk 1

    Unkown

    238.47GB 238.47GB

    Not Initialised Unallocated


    What can I do? Can i use command prompt to repair the MBR, and will that help? How can I ensure no data is lost? If I need to use a service, which should I use? Please help me, I'm at a loss what to do.


    The laptop was purchased in 2018, july

    :)

  2. unknown, Not initialize, unallocated external hard disk want to initialize

    I wanted to initialize unknown, unallocated,not initialize external hard disk, but when I go to disk manager and try to initialize the message pop up "Virtual disk manager access denied".

    Secondly, drive do not have any letter, and I CAN'T to assign letter to drive (in order to go for chkdsk in prompt command). when I right click on unknown & unallocated drive then there is only option left are properties help and offline.

    My question is how can I initialize the drive or bring the status online in order to assign drive letter and initialize the disk?
