How to Recover Data Lost by Diskpart Clean
If you ran diskpart clean on the wrong disk, you may have wiped the partition table and made the drive appear empty. This guide explains what the command actually does, what you need to attempt recovery, and the step-by-step process to get your files back. The good news: diskpart clean does not erase the underlying data—it only removes the partition structure, so recovery is often possible with the right tools.
What You’ll Need
- A second computer or an external drive to install recovery software on (do not install anything on the affected drive).
- Data recovery software that supports partition recovery or raw file scanning. Free options exist, but paid tools often offer better results for larger drives.
- A USB-to-SATA/IDE adapter or an external hard drive enclosure if you plan to connect the affected drive to another PC.
- Enough free space on another drive to store the recovered files.
Step-by-Step
- Stop using the drive immediately. Do not create new partitions, format the disk, or copy any files to it. Any new write operation can overwrite the data you want to recover.
- Identify the correct drive. If the drive is still connected, open Disk Management (right-click Start > Disk Management) and note the disk number (e.g., Disk 1). Do not confuse it with other drives.
- Connect the drive to a healthy computer. If possible, remove the drive from the original PC and connect it via a USB adapter or enclosure to a different computer. This avoids booting from the affected drive and reduces the chance of writes.
- Download and install data recovery software. On the healthy computer, install a reputable recovery tool. Popular options include TestDisk (free, open-source), Recuva (free for basic use), or commercial tools like EaseUS Data Recovery Wizard or Stellar Data Recovery. Choose one that supports partition recovery and raw scanning.
- Launch the software and select the affected drive. The software will list all physical drives. Select the one that corresponds to the disk you cleaned (match the capacity and model). Do not select a partition—select the whole physical disk.
- Choose a scan mode. If the software offers “Partition Recovery� or “Lost Partition� mode, use that first. If it doesn’t find your files, run a “Deep Scan� or “Raw Scan� which searches for file signatures sector by sector.
- Start the scan. The scan may take several hours depending on the drive size and speed. Let it run to completion—do not interrupt it.
- Preview and select files to recover. When the scan finishes, the software will show a list of found files and folders. Use the preview function to verify that the files are intact (especially images, documents, and videos).
- Recover the files to a different drive. Choose a destination that is not the affected drive. Create a new folder on your healthy drive and save the recovered files there. Do not save back to the cleaned drive.
- Verify the recovered files. After recovery, open a few files to confirm they are not corrupted. If some files fail, you may need to repeat the scan with a different tool or use a more advanced recovery service.
Common Mistakes
- Continuing to use the drive. Even browsing the drive with File Explorer can cause writes (e.g., thumbnail cache, system restore points). The moment you realize the mistake, disconnect the drive.
- Installing recovery software on the affected drive. The installation process writes files to the drive, potentially overwriting the very data you want to recover. Always install on a different drive.
- Creating a new partition or formatting. These actions write new structures to the disk and can make recovery harder or impossible.
- Choosing the wrong drive in the recovery tool. Double-check the drive capacity and model. Selecting the wrong drive could cause you to recover files from the wrong disk or even overwrite data.
- Using a quick scan only. A quick scan may miss many files. Always follow up with a deep/raw scan if the quick scan doesn’t find everything.
Tips
- Work on a copy if possible. If you have a spare drive of equal or larger size, you can clone the affected drive first using a tool like dd (Linux) or a disk imaging utility. Then run recovery on the clone, preserving the original.
- Prioritize important files. If the scan finds thousands of files, recover the most critical ones first (documents, photos, projects) before attempting to recover everything else.
- Use a tool that supports the file system. If the drive was NTFS (Windows) or APFS (Mac), make sure the recovery tool supports that file system. Some tools are better for specific file systems.
- Consider professional recovery for critical data. If the data is extremely valuable and DIY recovery fails, a professional data recovery service may be able to help, but it can be expensive.
- Keep the drive cool and stable. If the drive is making unusual noises, turn it off and seek professional help. Running a failing drive can cause further damage.
Troubleshooting
Scan finds no files. This can happen if the drive was formatted after the clean, or if the data was already overwritten. Try a different recovery tool—some are better at finding certain file types. Also, check that you selected the correct physical drive and not a partition.
Recovered files are corrupted. This often occurs when the file system metadata was partially overwritten. Try a raw scan that looks for file signatures (like JPEG headers) rather than relying on the file system. Some files may be unrecoverable if their data sectors were overwritten.
The drive is not recognized by the software. Ensure the drive is properly connected and powered. If using a USB adapter, try a different port or cable. In Windows, check Device Manager for driver issues. On macOS, the drive may appear as “uninitialized� – that’s normal.
Recovery software crashes or freezes. This can happen with very large drives or if the drive has bad sectors. Try running the scan in a different mode (e.g., raw scan) or use a more robust tool. Also, close other applications to free up memory.
You accidentally cleaned the system drive. If you cleaned the drive that contains the operating system, you cannot boot from it. You will need to connect it to another computer as a secondary drive to attempt recovery. After recovery, you may need to reinstall Windows and then restore your files.
Frequently Asked Questions
Does diskpart clean permanently erase data?
No. The clean command only removes the partition table and any volume information. The actual file data remains on the disk until it is overwritten. That’s why recovery is often possible.
Can I recover data after diskpart clean without software?
No. You need specialized software to reconstruct the partition structure or scan for raw data. There is no built-in Windows feature to undo the clean command.
How long does the recovery scan take?
It depends on the drive size and speed. A 1TB drive can take several hours for a deep scan. Quick scans are faster but less thorough.
Will recovery software harm my drive?
No, as long as you run it from a different drive and do not write to the affected drive. The software only reads the data. However, if the drive is physically failing, the read process could stress it further.
Can I recover data after I have already formatted the drive?
Yes, but it’s harder. Formatting writes a new file system, but the old data may still be present in unallocated space. A deep raw scan can often find remnants, but success is not guaranteed.
Is it worth paying for professional recovery?
If the data is critical and DIY attempts fail, yes. Professional services have cleanroom facilities and advanced tools, but they can cost hundreds or thousands of dollars. Weigh the value of the data against the cost.
