Partition Repair Software: Fix Damaged Partition on Windows 10/11

It is well known that a physical hard disk can be divided into multiple partitions, or “volumes,” such as C: or D:. Once a disk is partitioned, different types of directories and files can be stored on different volumes. More volumes offer more control, but too many can become unwieldy.

In fact, many users have experienced the issue of system unable to find partitions. This can happen when a partition is deleted, lost, or damaged due to virus attacks, improper operations, corrupted partition table, bad sectors, or sudden power outages. In such cases, to access files on the damaged partition, data recovery from the damaged partition and subsequent repair is required.

Next, we will show you how to perform a partition repair and recovery in several ways.

Extended Knowledge - What are the purposes of partitioning?

We can summarize the purposes of partitioning as follows:

• Keep your operating system files, common applications, and user data together.
• Set aside an area for the operating system's virtual memory swapping/paging.
• Keep cache and log files separate from other files.
• Use multiboot setups to allow users to install multiple operating systems. For example, you can install Mac OS X, Microsoft Windows, and others on different partitions of the same hard drive.
• Protect or isolate files so they're easier to recover in case of partition failure. If one partition fails, the other file systems will be unaffected and data on the drive may still be recoverable.
• For smaller systems, overall computer performance will increase.
• Connect any external hard drives, USB devices, or SD cards that you plan on losing partitions on to your computer now.
