In this post, what we are going to talk is how to recover deleted partition Windows 10.

    Reasons behind Partition Loss

    Although most of the time we are taking great care while operating computer, some accidents can still happen without our attention. For example, the following situations are the main causes of partition loss:

    1. Accidental deletion. If you accidentally carry out the followings, partition loss happens without a backup.
    • Wrong deletion: probably you rearrange hard drive partitions and then you accidentally delete a partition you need.
    • Clean on the wrong disk: you think you are clean on only one partition in diskpart but in fact, all partitions on the drive are cleaned.
    • Clean the whole drive while reinstalling operating system: when you reinstall Windows, you are likely to tell Windows to clean the whole drive but actually, you want to clean the original system partition.
    2. Corrupt partition table: due to improper operations or virus/malware attack, the partition table can get damaged and leads to partition loss.
    3. Power outage: if power surges while the partition is being read/write accessed, a partition may get corrupt and therefore no longer be displayed.
    4. Hardware issues: one or more hardware issues may cause corruption in a partition and make it missing, even if the hard drive itself is healthy.
    5. Bad sectors: a partition may get corrupt due to a large number of bad sectors, hence it may no longer be displayed or the operating system reads it as Bad Disk.

    And in this post, we mainly focus on how to recover lost partition on external hard drive/hard disk drive/SSD/USB flash drive caused by the former 3 reasons.

    "Hello, please an answer, what should I do first in my case? I did use CMD with next commands: clean disk and convert MBR to GPT, now my disk is in another PC and is in unallocated state.
    What? Is there a better way to try recovering some files, to convert the disk back to MBR, or try to recover as it is now(GPT), please answer.
    Thank you very much, all the best."
