In Disk Management, the lost partition will appear as extra unallocated space rather than the original partition. However, sometimes you might find your partition is lost, and you are unable to see it in Windows File Explorer. A partition can be created either during Windows installation, in Disk Management, by using the DiskPart command, or through a specialist third-party tool. Generally, you should partition a storage device into one or more partitions before you use it to store data. “Oops! I’ve accidentally lost my partition!”
