A Hard Disk Drive (HDD) contains one single undivided memory space. However, you can logically divide its memory into different isolated sections called partitions for better data management.
Things appear smooth while everything is fine with your hard drive. But, if you’ve somehow lost or accidentally deleted a hard drive partition with a lot of your critical data, it may bring you trouble.
Don’t worry! deleted partition recovery is possible.
We have mentioned the most effective DIY methods to help you recover lost, inaccessible, or deleted hard drive partitions. However, let’s first learn all the possible reasons for partition loss.
Common Reasons for Lost/ Deleted Partition on Windows 10/11:
The most common reasons for partition loss are as follows:
- Partition Table Corruption: A partition table acts as a guide for the OS to identify the traits of a partition. Sometimes, the partition table can be damaged by a virus or faulty disk operation, leading to corruption. A corrupt partition table means the partition doesn’t exist for your OS.
- MBR corruption: Master Boot Record (MBR) helps determine the location of your OS and assists in executing the booting process. MBR corruption renders the partitions on your PC inaccessible.
- Accidental deletion: Unintentionally deleting or formatting the wrong partition is among the most common partition deletion causes. As a thumb rule, always double-check before you confirm the deletion of any file.
- Interruption while resizing the partition: If you are resizing the partitions on your hard drive and any mishap disrupts the process, it may cause partition loss.
- Running CHKDSK after Disk Defragmentation: Always run the CHKDSK command before the defrag procedure. A faulty Disk Defragmentation followed by the CHKDSK command may cause troubles like errors in the partition table.
- Power outages: A sudden power surge or power failure can affect the drive’s operations and make the partition inaccessible.
- Bad sectors: Bad sectors on the disk may prevent your OS to recognize a partition.

Step 6: Type Exit and press Enter.
Now, check if you can access the partition you lost/deleted.
Method 4: Recover Unallocated Hard Drive Partition
Sometimes, when you connect your hard drive to a system, the system may detect it but not show it in the File Explorer. And, when you check it in Disk Management, it appears as ‘Unallocated.’ To recover data from an ‘Unallocated’ hard drive, follow the steps below:
Step 1: Go to Disk Management and locate the ‘Unallocated’ partition.
Step 2: Right-click on the unallocated partition and click New Simple Volume.
Step 3: Now, select ‘Assign the following drive letter,’ choose a letter from the drop-down list, and click Next.
