User case: accidentally deleted a partition on win10


I accidentally made a mistake and already deleted a wrong selected partition with data on it through diskpart app on win10. I have a backup of course but some of the files are not included in the last backup. It is my home pc, not a big deal but I would like to recover the partition. Is there a good and free app to do that kind of task? Or what do you prefer from a commercial app to buy for home users?




Are you looking for a partition recovery tool to recover deleted partitions in Windows 10/11 which have been accidentally deleted or lost? You come to the right place. If the deleted partition contains vital files, it could be disastrous. However, recovering deleted partitions and data in Windows 10 is not a difficult task. Find the best partition recovery software to recover the entire deleted partition and data easily.

What to do after deleting a partition or volume?

It is possible to recover the deleted partition and data with it. Because when a partition is deleted, the operating system only deleted its records from the partition table and you couldn’t access it via File Explorer.

The data on the partition will not be erased immediately, and it will be stored in a hidden place on the disk. After deleting a partition or volume, the space of the deleted partition will become “Unallocated” in Disk Management. In this case, a professional partition recovery tool would be the best helper to retrieve the lost partitions and data from the unallocated disk space.

To protect your partitions and data from further loss and make sure lost or deleted partition recovery can be performed successfully, there are some tips for you to notice after deleting a partition or volume.

1. Stop using the hard drive

When you lose or delete a partition on a hard drive or external hard drive, you should immediately stop using it. Additionally, do not save data or create a new partition on the storage device. Otherwise, the data from the deleted or lost partition will be covered or overwritten.

2. Do not make changes to the partition table

Once the partition table has been modified or changed, it will be difficult to restore lost partitions. Therefore, do not make the following operations: repartition the hard disk, resize partition, convert partition type, convert partition table type, etc.

3. Try professional partition recovery software instead of CMD

Some guides advise restoring the partition using CMD commands, like assigning a driver letter. It only suits for the partition is invisible in File Explorer due to the drive letter missing. You’d better use a professional partition recovery tool to recover deleted partitions with simple steps.
