Common Reasons That Cause Deleted&Lost Partitions

Several factors may contribute to your lost partition, like partition table errors, file system changes and more

Disk Management Tools Malfunction

Errors or bugs in disc management tools or third-party partitioning software can sometimes cause unintended changes to the file system, which can cause partitions to be lost or removed.

Partition Table Errors

Partitioning a disc is necessary for it to function, as the OS has to know which sections of the disc it may utilise to store information. The partition table enables the OS to recognize the internal devices properly. Partitions will be lost if the table is lost, corrupted, or otherwise compromised.

Incompatible File System with OS

Even though most modern file formats are compatible with most modern operating systems, there are several notable exceptions. For example, Ext2, Ext3, and other Linux system formats are not recognised by Windows computers. If you follow Windows’advice and initialise the drive, all your files will be deleted.

File System Changes

The file system is the underlying structure used to organize and manage data on a storage medium, such as a hard drive or SSD. Changing the file system for the formatted partition (e.g., from FAT to NTFS) can damage service data and lead to lost partitions.

Operating System Reinstallation

Users often have to choose a target drive or section when installing or reinstalling an operating system. If they aren’t careful, they might choose the wrong partition to put the OS on, which would cause the data in the chosen partition to be lost.

Data Corruption

The partition table can sometimes be broken by a virus, bad disc processes, or a storage device that has been hacked. When these things happen, a lost partiton might happen.
