Is there any way I can recover the lost partition?
Partition loss is one of the most commonly occurring problems in the operating system. It’s very unpleasant when you can’t find the partition and files where you expect them to be.
Lost partition recovery is different from restoring deleted or lost files. Compared with single files, the former should look for a whole partition. If you want to recover both lost files and partitions, please pay attention to the following tips:
- Do not make any new operation to the hard drive and the partition.
- Do not reformat the hard drive.
- Do not rebuild the partition table.
How does a partition become "lost"?
To prevent partition loss from happening again in the future, you’d better know the reasons why a partition becomes lost. There are a few factors that cause partition loss or deletion.
Disk management errors. When operating disk management, it’s easy to delete partitions by mistake. You may delete a partition or damaged the partition table when making some wrong operations in disk cleaning or resizing a partition.
Unexpected system shutdown. Frequently system shutdown unexpectedly could cause computer faults, even hard drive errors. In this case, the partition can get lost.
Data corruption. If your operating system or file system becomes corrupted, then the hard drive cannot run correctly, which may make partitions inaccessible.
Virus Infection. Virus and malware become increasingly complex and quite difficult to be detected and eliminated. Once the hard drive gets virus-infected, partitions can be deleted easily.
Bad Tracks/Sectors. If there are many bad sectors on a partition, the partition can be inaccessible and unable to be recognized by the operating system.
Run CHKDSK after Disk Defragmentation. The hard drive structure will get corrupt running CHKDSK when disk defragmentation finishes, and then, the partition gets lost.
Fortunately, you can recover the lost partition if you act as soon as possible after the deletion or loss. AOMEI Partition Assistant can make things easier with a concise interface and simple operations for anyone.
What is lost partition recovery?
Normally, the partition is recognized by your computer via its partition table and boot sector. When a partition is deleted, the operating system deletes its information like partition type, size, and file system, from the partition table but keeps sectors taken by the volume. You just only can’t see the deleted or lost partition in Disk Management and Windows File Explorer.
Therefore, if you accidentally deleted or lost a partition, there is still an opportunity to restore the lost partition if the section isn’t covered or rewritten by new data with the help of professional partition recovery software. Or you can recover lost partitions via CMD to assign a drive letter to the lost partition.
