Can I Recover Accidentally Deleted Partitions

Yes, you can recover a partition that you've accidentally deleted. When you delete a partition, the data doesn't disappear from the disk right away. 

Instead, the space assigned to the partition is labeled as unallocated. You can usually recover data from deleted partition as long as new data doesn't overwrite this space.

Keep in mind that the success of recovering an accidentally deleted partition depends on factors like how much new data you've added to the disk after deleting the partition. 

Remember that acting quickly and avoiding the addition of new data to the affected drive increases your chances of a successful recovery.

Method 1. Recover Data from Accidental Deleted Partition with Recovery Software

The good news is that users can get the EaseUS Data Recovery Wizard. It serves as a recovery software for retrieving lost data from diverse sources, including hard drives, memory cards, external hard drives, SD cards, and more.
