Is it possible to recover missing partitions in Windows 10?

Generally, the hard drive is logically divided into several parts called partitions. Although the partition is convenient for users to store system and personal data separately, sometimes, it will become inaccessible or not show up due to missing drive letter, accidental deletion, corruption, or other unknown reasons.

Fortunately, in some situations, it's possible to recover missing partition in Windows 10. The operating system just removes its information (eg: partition type, size, file system, and location) from the partition table when a partition gets lost. In Disk Management, the missing partition is often marked with an asterisk, Unallocated, or RAW.

⚠️Any operation on a lost or missing partition can lead to more problems or even data loss. Thus, you need to perform partition recovery as soon as possible.

Why is your partition missing in Windows 10?

What causes a lost partition? Before trying to recover the missing partition in Windows 10, it is important to find out the reasons for avoiding partition loss in the future. Windows 10 partitions might miss for a variety of reasons. Usually, the following factors can cause missing partitions.

  • Users’ improper operation
  • Partition table corruption
  • Loss of the volume label, drive letter, or partition name
  • Bad sectors or tracks
  • Unexpectable Power failure
  • Virus attacks and malware
  • Repartition hard drive
  • Incompatible file system

The top two ways for Windows 10 missing partition recovery

If your partition is missing in Windows 10, all the data in the partition will be deleted eventually. There are two methods you can try to recover the missing partitions in Windows 10. Using reliable partition recovery software, like AOMEI Partition Recovery Wizard, is certainly the easiest one.

Before starting, please be sure you don't do the following items. They are risk of overwritting your data on the disk, making data recovery more difficult.

  • Make any new operations on the hard disk.
  • Create a new partition on the unallocated space.
  • Rebuild the partition table.
  • Reformat the hard disk.

Method 1: Recover missing partitions with professional partition recovery software

If the partition is missing, a professional partition recovery tool can rescue your partition and data. The Partition Recovery wizard, one of the built-in features of AOMEI Partition Assistant Professional, is created to recover deleted, lost, or missing partitions in Windows 10 or other operating systems.  

It provides two advanced scanning methods to thoroughly scan your disk and find all the recoverable partitions in simple steps. It applies to disk or partition formatted with FAT, NTFS, Ext2, Ext3, and Ext4 file systems.

  • Fast Search: It's the recommended method. It will scan your disk and find out deleted or lost partition quickly. If it is not working, you still can try Full Search.
  • Full Search: This method will scan every sector of the selected disk. Thus, it will be more time-consuming.
