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 seem pretty easy while everything is fine with your hard drive. But, if you somehow lose or accidentally delete the hard drive partition with so much of your essential data, it will become troublesome with a blink of an eye.

Don’t worry! HDD partition recovery is possible.

We have mentioned some effective DIY methods to help you recover lost, inaccessible, or deleted hard drive partition. However, first, we would like you to know all the possible reasons for partition loss.

Reasons for Partition Loss:

The most common reasons for partition loss are as follows:

  • Partition table corruption or loss
  • MBR corruption
  • Accidental deletion
  • Interruption while resizing the partition
  • Sudden system shutdown
  • Bad sectors on the hard drive
  • File system corruption
  • Running CHKDSK after Disk Defragmentation

How to Perform HDD Partition Recovery?

Method 1: Assign a Drive Letter

When you try to access your hard drive in Windows File Explorer, there could be chances you may not be able to find it there. One possible reason behind it could be no drive letter assigned to the drive. To confirm the same, you need to go to Disk Management and check if there is any partition with some storage consumption but no drive letter assigned to it.

If you find any such drive partition, perform hard disk partition recovery by assigning a drive letter and get back your access to the drive. To do so, follow the below-mentioned steps:

a. Press Windows + X, locate and click Disk Management. (See Image 1)

Method 2: 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.
