To recover deleted NTFS partition data, distinguish missing partition information from an unreadable file system, restore the correct volume, and verify its files.
A deleted NTFS partition and an existing volume that has become RAW can both make files inaccessible, but they describe different problems. Before attempting recovery, check whether Windows still shows the original volume’s boundaries.
If the partition is missing, partition recovery may restore the volume and its data. If the partition remains but its file system cannot be read, restoring partition information alone may not resolve access.
Do not format the space as NTFS to put the old file system back. Formatting prepares a new file system rather than recovering the previous one.
Open Disk Management and locate the disk that contained the NTFS data volume.
| 🚦 Current Status | ⚠️ The Issue |
|---|---|
| Unallocated space where the volume used to be | Missing partition information |
| Existing volume labeled RAW | Unrecognized or damaged file-system information |
| Healthy NTFS data volume without a letter | Missing access letter |
| Accessible volume with several missing files | File deletion |
| Visible files producing Access Denied | Permissions or encryption |
These conditions require different decisions.
For the wider partition recovery, see how to recover deleted partition with data.
A partition is a section of a disk. NTFS is the file system that keeps track of the files stored there.
NTFS uses a Master File Table (MFT) to record details such as file names and where their data is stored. If these records or the file data are damaged, recovery software may find the original partition, but some files may still be unreadable. A visible filename alone does not mean the file is complete.
You do not need to edit the MFT yourself. Follow the partition recovery steps below, then open your important files to check that they work correctly.
Partition recovery is worth considering when a standard NTFS volume is deleted and the source disk is still readable. You need to record any later changes:
| 📝 Later operation | 💡 Why it matters |
|---|---|
| Created a new partition | Introduced a new layout |
| Formatted the affected area | Replaced file system information |
| Extended a neighboring volume | May overwrite original data |
| Copied files to a new partition | May overwrite original data |
| Continued using an unstable disk | May complicate reliable access |
Deleting the new volume will not undo the changes or restore the original partition. If all partitions disappeared after using Diskpart command, review how to undo DiskPart Clean first.
AOMEI FastRecovery is Windows data recovery software with a Partition Recovery feature that restores a missing partition and the data inside it. It provides users with two scanning methods:
Download and install the software on a different physical drive, not on the NTFS partition you're trying to recover. Even a healthy partition on the same disk isn't safe.
A reliable Windows data recovery software that easily recovers deleted or lost partitions, or retrieve files.
Step 1. Open AOMEI FastRecovery, and select Disk Data Recovery > Partition Recovery.
Step 2. Check the disk number, capacity, model, and displayed layout. Select the entire disk containing the deleted NTFS volume, then click Next.
Step 3. Choose Fast Search to find deleted or lost partition quickly. If not, click Back, select Full Search instead. Full Search scans the disk more extensively and generally takes longer.
Step 4. Compare the detected file system, capacity, sector boundaries, and Primary/Logical flag with the former volume to find the deleted NTFS volume.
Step 5. Select the deleted NTFS partition and click Proceed.
After the restoration finishes, check the volume in Disk Management, then open its folders and files in File Explorer to confirm everything is there. Cancel any formatting prompt that appears.
For external hard drive partition recovery, make sure you have a reliable access and don't use the lost partition.
Check more than whether the old drive letter returns.
Folder structure: Confirm that all expected directories exist, including nested project folders and locations outside your usual document library.
File content: Open a few files of different formats and sizes to make sure everything works normally.
Completeness: Check supporting assets, linked media, and accompanying databases. A main file may open while related content is missing.
Copy verified files from the restored partition to another physical drive before reorganizing the source. This protects a separate copy of the accessible data while you finish checking the recovered volume.
| ⚠️ Remaining symptom | ✅ What to do next |
|---|---|
| Volume appears as RAW | Recover data before considering repair |
| Some files open and others fail | Back up the files that are working, and check the rest separately. |
| Files show Access Denied | Check the permissions or encryption issue |
| Disk disconnects or develops read errors | Stop scanning and reassess hardware |
Don't run any repair commands until you've saved your important files. Repairs change the drive, which can ruin your chances of getting your data back.
Will formatting as NTFS restore the old files?
No. Selecting the same file system does not reconstruct the original file records, folders, or content.
Does the original drive letter have to return?
No. A different letter does not, by itself, indicate failure. Check that the correct volume and expected files are accessible.
Can partition restoration bypass encryption?
Do not assume so. Restoring a volume does not establish that encrypted content can be opened without the necessary credentials.
Recovering a deleted NTFS partition requires identifying the missing volume before changing its file system. Restore only a candidate that fits the original layout, then verify actual file content and secure it on separate storage.
