How to Recover a Hard Disk Partition in Windows 10/11

What Is a Hard Drive Partition

A hard drive partition is a logical section of a physical disk that Windows treats as a separate drive. Each partition has its own drive letter, label, file system, and capacity so that you can store system files, programs, and personal data separately.

You can view all partitions in Disk Management. When you connect a new drive, Windows asks you to initialize it as GPT or MBR. Then right-click the unallocated space and follow the New Simple Volume Wizard to create partitions.

Common Causes of Partition Loss

Although hard disk partitions make data management easier, we have to pay attention to the followings that may lead to partition loss:

• Human errors: when doing hard disk management, we may accidentally delete a necessary partition or carry out diskpart clean on the wrong drive that contains important files, leading to partition loss.
• Power Surges: while a partition is being read accessed or write accessed, power surges or power fluctuations may lead to corruption in the partition, making the partition disappeared.
• Virus Infection: Virus intrusion or malware infection may bring corruption in the partition header, hence the infected partition may disappear.
• Hardware Issue: One or more hardware issues may cause corruption in a partition or make it disappear, even if it is healthy. Besides, if there are a large number of bad sectors, or bad RAM, a hard drive may no longer display partitions or the operating system fails to read it.
• Windows update: Some updates have been reported to cause partition loss.

Can you recover a lost partition? Yes, if the partition area has not been overwritten by new data. Stop using the affected drive right away, then run a professional partition recovery tool.
