A missing partition does not always mean your files are gone. This guide helps you check whether an NTFS partition was deleted, lost its drive letter, or became unreadable. This guide explains how to handle deleted or corrupted NTFS partitions, check unallocated space in Disk Management, and use Windows tools or data recovery software to retrieve lost files.
Yes, you can often recover a deleted NTFS partition if enough of its original information and file contents remain intact. Deleting a partition usually removes the record Windows uses to locate it, rather than immediately erasing everything inside. Recovery software can search for the remaining NTFS information to help locate the original partition and recover its accessible contents.
The chances depend on what happened after deletion. Creating a new volume, formatting it, or saving new files in the same space can overwrite information needed for recovery. On SSDs, TRIM may also make some contents unavailable. Even if the partition can be restored, individual files may have been damaged or erased.
Keeping the affected space unchanged gives recovery tools a better chance. Before choosing a method, though, check whether the partition was actually deleted: a missing drive letter or a damaged file system can also make a drive disappear from File Explorer.
An NTFS partition can disappear because it was deleted, its partition information was changed, or Windows can no longer read it. What you were doing just before it disappeared can help narrow down the cause:
These situations need different responses. Disk Management can help you check which one you are dealing with before you attempt recovery or repair.
Disk Management lets you check whether the partition is still present and how Windows recognizes it. This helps you choose between recovering a deleted partition, investigating damage, or restoring a missing drive letter.
Step 1: Open Disk Management. Right-click Start and select Disk Management. If Windows asks you to initialize or format the affected disk, cancel the prompt.
Step 2: Find the affected disk. In the lower panel, identify the physical disk by its capacity and existing partitions. Locate the area where your missing partition used to be. Do not assume that Disk 0 is the correct disk.
Step 3: Check what Windows shows. Use the table below to decide which path fits your situation.

What Disk Management shows |
What it may mean |
Where to go next |
|
Unallocated where the partition used to be |
The partition was deleted or its record was lost |
Use the deleted-partition recovery methods below |
|
A partition marked RAW |
The file system cannot be read; damage is one possible cause |
Protect needed data, then investigate the corruption |
|
NTFS is shown, but the drive will not open |
File-system errors, access permissions, or another problem |
Check the error message; use repairs only for a confirmed file-system problem |
|
A healthy NTFS data partition with no letter |
The partition may still be intact |
Check whether assigning a letter is all that is needed |
Step 4: Assign a letter only if the data partition is intact. Right-click the verified NTFS data partition, choose Change Drive Letter and Paths > Add, and select an unused letter. If it opens, back up your important files. Leave EFI, recovery, and other system partitions unchanged.
If Disk Management shows unallocated space where your NTFS partition used to be, you can search for the original partition using either method below. Start with MyRecover if you prefer a graphical interface; TestDisk offers an alternative for users comfortable with keyboard-driven menus.
MyRecover includes Partition Recovery to help restore a deleted NTFS partition together with its recoverable files and folders. You can select the affected physical disk even when the old drive letter has disappeared and its space now shows as unallocated. The graphical interface displays the partitions it finds with details such as their file system, capacity, and location. This gives you a clearer way to identify the partition you lost without navigating text menus or manually setting partition status flags.
Step 1: Install and open MyRecover. Download MyRecover from official webiste and install it on a separate, healthy physical disk rather than the affected disk. If the affected disk also contains your running Windows installation, keep further Windows use to a minimum to reduce background writes that could overwrite recoverable data.
Step 2: Select the disk containing the deleted partition. Open Partition Recovery, match the disk by model and capacity. Select the physical disk where the old partition was stored, even though its drive letter has disappeared and click "Next".
Step 3: Search for the lost partition. Choose "Fast Search" and click "Next". If it does not find the partition you expect, try "Full Search", which examines more of the disk and takes longer.
Step 4: Check the result before restoring it. Compare the listed NTFS partition's size and position with the one you deleted. The start and end sectors describe where it sits on the disk. Select the matching partition and click "Proceed".
Step 5: Check and back up your files. Open familiar folders and several important files, since a restored partition may still contain files damaged or overwritten before recovery. Copy readable contents to another physical disk before making further partition changes.
TestDisk offers another way to find a deleted NTFS partition and write its entry back into the disk’s partition table. Unlike MyRecover’s graphical interface, it uses text menus controlled with the keyboard and asks you to check the proposed partition layout before saving changes. You can list files inside a found partition to help confirm that it is the right one. Writing an incorrect layout can make existing partitions inaccessible or complicate further recovery, so this requires careful checks of the partition sizes, positions, and status before saving changes.
Step 1: Start TestDisk as administrator. Download and extract the Windows version onto a healthy disk, then right-click testdisk_win.exe and choose Run as administrator. Select Create to start a log.
Step 2: Choose the correct physical disk. Match its capacity and model to the affected disk, then select "Proceed".
Step 3: Confirm the partition-table type. Check the detected option against the disk’s known layout: EFI GPT for GPT disks or Intel for standard MBR disks. NTFS is the file system, while the Intel option refers to a partition-table format, not your processor.
Step 4: Search for the deleted partition. Choose Analyse, then Quick Search. Highlight a likely NTFS result and press P to list its files. Check for familiar folder names, not just an NTFS label. Press Q to return. If the partition is missing, use Deeper Search.
Step 5: Verify the complete partition layout. Confirm that all partitions you need are present, correctly sized, and do not overlap. For MBR disks, check the appropriate primary or logical status, and do not mark a data partition bootable merely to restore it.
Step 6: Save only a confirmed result. Choose Write and confirm with Y only when the complete layout is correct. If files cannot be listed or the results are unclear, quit without writing changes.
Step 7: Check the recovered partition. Restart if prompted, then open the drive and check important files. Back up accessible contents to another physical disk before attempting any further repairs.
If your partition still appears in Disk Management but shows RAW, asks to be formatted, reports file-system errors or cannot be opened, it may be damaged rather than deleted. The methods below address two specific problems: a damaged NTFS boot sector and errors within an NTFS file system.
If you cannot open the partition or access the files in the partition, recover the files you need before attempting repairs. TestDisk and CHKDSK can change information on the partition, so saving recoverable files elsewhere first helps protect them if a repair does not work as expected. MyRecover can scan the inaccessible partition for recoverable contents and save selected files to another drive. Do not format it if Windows displays a prompt.
Step 1: Launch MyRecover. Open the application on a separate, healthy physical disk where possible and prepare a separate physical disk with enough free space for the recovered files.
Step 2: Scan the affected partition. Locate the drive where the inaccessible partition was by its capacity and position, then select it and click "Scan". If you can't find the partition you're looking for, it may be listed as a "Lost Partition".
Step 3: Review the files found. Use "Filter" or "Search" to locate important files and preview the file content. Check the contents you need rather than relying on file names alone.
Step 4: Recover to another physical disk. Select the files and click "Recover", then choose a destination outside the affected disk. Open the saved copies to confirm they are readable before proceeding with either repair method below.
The NTFS boot sector contains information Windows needs to read a partition, including how its storage space is organized. If this information is damaged, Windows may display the partition as RAW or ask you to format it. TestDisk checks the main boot sector and its backup to help identify whether either copy is damaged. If a valid backup is available, it may be used to restore the main copy. When neither copy is usable, TestDisk can attempt to rebuild the information using the remaining NTFS records.
Step 1: Open TestDisk and select the affected disk. Run testdisk_win.exe as administrator, choose Create, and select the physical disk by its model and capacity. Confirm the correct partition-table type, using EFI GPT for GPT or Intel for standard MBR layouts.
Step 2: Open the NTFS boot-sector screen. Choose Advanced, highlight the affected NTFS partition, and select Boot. Check that its size and location match the partition you intend to repair.
Step 3: Check the main and backup status. Read the results beside Boot sector and Backup boot sector. If both show OK, do not replace either simply because Windows cannot open the drive; another problem may be responsible.
Step 4: Restore a valid backup when appropriate. If the main boot sector is Bad, the backup is OK, and you have confirmed the correct partition, choose Backup BS and confirm after protecting your data. Do not choose Org. BS for this situation, because it copies the main sector over the backup instead.
Step 5: Consider rebuilding only if neither copy is usable. Select Rebuild BS, then use List to check whether the expected files and folders appear. Choose Write only after verifying the result; if the files are missing or the result is unclear, quit without writing.
Step 6: Check access again. Exit TestDisk and reconnect the data drive or restart if needed. Try opening the partition and copy important files elsewhere if access returns.
If Windows still recognizes your NTFS partition but reports file-system errors, its built-in CHKDSK tool may help restore access. NTFS uses records to track where files are stored and how folders are organized. Errors in these records can prevent files or folders from opening even when their contents remain on the drive. CHKDSK checks these records for problems, such as incorrect file links or folder index entries. Running it with the /f option repairs supported errors, which may make the affected files and folders accessible again.
Step 1: Open an administrator command prompt. Search for "Command Prompt" in "Start", right-click it, and choose "Run as administrator".
Step 2: Check the volume without requesting repairs. Enter chkdsk E: (Replace the drive letter E with your actual drive letter）and read the report. If it says CHKDSK is unavailable for RAW drives, stop this method rather than format the partition to make it work.
Step 3: Repair confirmed file-system errors. Once your needed data is protected, enter chkdsk E: /f if the report identifies errors that require repair. The /f option writes changes, so use it on the verified volume only. If CHKDSK cannot lock the drive, close applications and follow its scheduling prompt when appropriate. Do not automatically force a dismount.
Step 4: Review the result and check your files. Let CHKDSK finish, then read its final report and try opening the affected folders. If access returns, update your backup; repairing file-system errors does not restore contents that were already overwritten or erased.
Check the partition's state before choosing a tool. For deleted NTFS partitions, preserve the original space and search for the correct partition with MyRecover or TestDisk. For a partition that still exists, confirm the fault before using TestDisk boot-sector repair or CHKDSK. These repairs serve different purposes and should not be run one after another without a reason.
Once the partition and files are accessible, back up important contents to a different drive. For IT teams handling deleted-partition recovery across company computers, MyRecover Technician provides unlimited use within one company.
Can I recover a deleted NTFS partition without formatting?
Yes, you may recover a deleted NTFS partition without formatting if enough of its original information and contents remain readable. Formatting creates a new file system and can overwrite information needed for recovery. Leave the space unallocated, avoid further writes, and scan for the original partition instead.
Can Disk Management or a drive letter restore a deleted NTFS partition?
No. Disk Management can help identify the problem, but creating a New Simple Volume does not recover the deleted partition. Assigning a drive letter helps only when an existing, intact data partition has lost its letter. If the original space is unallocated, use partition recovery software rather than creating a replacement volume.
Can I recover an NTFS partition after creating a new volume?
Possibly, but creating or formatting a new volume may overwrite information needed to recover the original partition. Stop using the affected disk. If the new volume occupies the old partition’s space, avoid writing the old layout back without careful assessment. It's best to make sure all your data has been recovered to a safe location before creating a new volume, if necessary.
Can a deleted NTFS partition be recovered from an SSD?
Yes, recovery may be possible from an SSD if the needed partition information and file contents remain readable. TRIM and later writes can limit what survives. A successful partition search does not prove every file is recoverable, so avoid further use and check important contents after recovery.
Does a RAW partition mean my files are permanently lost?
No, RAW means Windows cannot recognize a usable file system on that partition; it does not by itself prove permanent loss. Damaged NTFS information is one possible cause. Avoid the format prompt, protect needed data, and identify the fault before attempting a repair that changes the drive.
