Deleted a volume in Disk Management by mistake? Don't panic. Learn two easy ways to recover your deleted partition and lost data in Windows 10/11.
If you accidentally deleted a volume in Disk Management, it may disappear from File Explorer, and its former space may show as Unallocated. This can be alarming if the volume contained important documents, photos, videos, or work files.
When you select Delete Volume in Windows Disk Management, Windows removes the volume's partition entry and makes its space available for reuse. This operation does not necessarily erase every file immediately, so recovery may still be possible if the underlying data has not been overwritten.

Before trying either recovery method, take these precautions to protect your data.
If the lost volume contains irreplaceable data, prioritize recovering the files before attempting to restore or rebuild the partition structure.
This method applies when the volume was not actually deleted and only its drive letter was removed. Disk Management cannot directly undo a deleted volume or restore its original partition entry simply by assigning a drive letter.
If the partition still appears in Disk Management with a healthy file system but no drive letter, follow these steps.
Step 1. Press Win + X and select Disk Management.
Step 2. Locate the affected disk and inspect its partitions. Confirm that the missing volume still exists and is not marked as Unallocated.
Step 3. Right-click the existing partition that has no drive letter and select Change Drive Letter and Paths.
Step 4. Click Add, select Assign the following drive letter, and choose an available letter from the list.
Step 5. Click OK to apply the change.
Step 6. Open File Explorer and check whether the volume is accessible. If the volume reappears, verify that your files are intact before making any further changes.
If you selected Delete Volume and the space now appears as unallocated, a dedicated Windows partition recovery tool - AOMEI FastRecovery can help you recover data from deleted partition along with the partition entry.
Follow the instructions below to recover deleted volume in Windows 10/11 via AOMEI FastRecovery:
Step 1. Download and install AOMEI FastRecovery on a different drive from the one containing the deleted partition. Launch the software, select Disk Data Recovery, and click Start Partition Recovery.
Step 2. Locate the disk where the partition was deleted by checking its disk number, capacity, model, and partition layout. Select the disk and click Next.
Step 3. Choose a search method and click Next to start scanning. Select Fast Search to quickly locate deleted or lost partitions.
Step 4. Once the scan is complete, review the detected partitions and their details. Select the partition you want to recover and click Proceed.
💡 Note: If the desired partition is not listed, click Back and try Full Search to perform a more thorough scan.
Step 5. After the recovery process finishes, open File Explorer to check the recovered partition. If it does not appear, try assigning it a drive letter through Disk Management or restarting your computer.
1. Can I undo deleting a volume in Disk Management?
Windows Disk Management does not provide a simple undo option for Delete Volume. If the volume was deleted, you may need partition recovery software or a backup to recover the partition and its files. If you only removed the drive letter, assigning a new letter may restore access.
2. Can I recover a deleted volume without losing data?
Yes, recovery may be possible if the original data has not been overwritten. Stop using the affected disk, avoid creating a new volume, and recover important files to a separate drive. No method can guarantee recovery in every situation.
3. Does creating a new simple volume overwrite my deleted files?
Creating a new volume changes the disk's partition information and may lead to data being overwritten, especially if you format it or save new files. If you accidentally deleted a volume and need its data, do not create a new simple volume until you have assessed your recovery options.
If you accidentally deleted a volume in Disk Management, the right recovery method depends on whether the partition still exists.
Above all, avoid creating a new volume or formatting the affected space before recovery. The sooner you stop writing to the disk, the better your chances of preserving whatever data remains recoverable.
