How to Repair or Recover Corrupted, Deleted or Lost Partitions

As we know, one physical disk can be divided into several partitions (the drive letters such as C:, or D:), they are also called "volumes". Once a hard disk is divided into several partitions, directories and files of different categories may be stored in different partitions. More partitions provide more control but too many may become cumbersome. 

Actually, many users have the experience that system can not find partitions. The problem can occur when the partition is corrupted, deleted or get lost due to other reasons. And in this situation, if you want to access to these files on this partition, you have to find a partition recovery or repair solution first. Next, we will show you how to manage the job step by step.

Expanded Knowledge - What are the purposes for partitioning

We can conclude the purposes of partitioning as the following:

(1) Keeping Operating System files, frequently used programs and user data near each other.

(2) Having an area for Operating System virtual memory swapping/paging.

(3) Having cache and log files separate from other files.

(4) Use of multi-booting setups, which allow users to have more than one. For instance, one could install Mac OS X, Microsoft Windows or others on different partitions of the same hard disk.

(5) Protecting or isolating files, to make it easier to recover data from corrupted partition. Other file systems won't be affected and the drive's data may still be salvageable if one of partitions is corrupted.

(6) Raising overall computer performance on systems with smaller partition is more efficient.

Connect the device - external hard drive, USB or SD card on which you lost partition to your PC in advance.
