Recuva cannot scan or recover files from Ext4 partitions

Recuva is a Windows-only tool that works with Windows file systems — NTFS and FAT32. It cannot read Ext4, the standard file system for Linux. If your drive is formatted as Ext4, Recuva will not see the files on it, and you cannot use it to recover data from that drive.

This is a hard technical limit, not a setting you can change. Recuva's code was built to understand how Windows stores and deletes files. Ext4 stores data differently — different file structure, different deletion markers, different recovery signatures. Recuva simply does not have the logic to interpret Ext4 data.

If you have a Windows drive and need recovery, Recuva works well. If you have a Linux drive or a drive that was formatted on a Linux machine, you need a different tool.

Key Takeaways

  • Recuva works only on Windows file systems (NTFS and FAT32), not on Ext4 or other Linux file systems.
  • You can check what file system a drive uses by right-clicking it in Windows File Explorer, selecting Properties, and looking at the file system field.
  • For Ext4 recovery on Windows, tools like TestDisk, PhotoRec, or R-Linux can read the file system and recover deleted files.
  • If the Ext4 drive is connected to a Linux machine, command-line tools like extundelete or e2fsck are often faster and more reliable.

How to check what file system your drive uses

Before you try any recovery tool, confirm whether your drive is actually Ext4. In Windows, plug in the drive, open File Explorer, right-click the drive letter, and select Properties. The file system will be listed near the top — it will say NTFS, FAT32, Ext4, or something else.

If it says Ext4 (or ext3, ext2, or any other Linux file system), Recuva will not work. If it says NTFS or FAT32, Recuva can scan it.

On a Mac, click the drive, press Command+I, and look for the format field. On Linux, open a terminal and run lsblk -f to see all connected drives and their file systems.

Tools that work with Ext4 on Windows

TestDisk and PhotoRec are free, open-source tools that run on Windows and can read Ext4. PhotoRec is the file recovery part — it scans the drive sector by sector and pulls out deleted files by their file signatures (the data patterns that mark the start of a JPEG, PDF, document, etc.). It does not rely on the file system structure the way Recuva does, so it works across file systems.

R-Linux is another free option that understands Ext4 structure directly. It shows you the file tree and lets you pick which files to recover, which is faster than PhotoRec if the file system is still partly readable.

Both are slower than Recuva on Windows drives, and both require more patience with the interface. But they will recover files from Ext4 when Recuva cannot.

Recovery from Ext4 on a Linux machine

If you can connect the Ext4 drive to a Linux computer, recovery is usually faster and more reliable. The Linux command line has native tools that understand Ext4 deeply.

extundelete is the most common choice. You install it (usually sudo apt install extundelete on Ubuntu or Debian), then run a command like extundelete --restore-all /dev/sdX1 (replacing sdX1 with your actual drive). It recovers deleted files into a RECOVERED_FILES folder.

e2fsck is another option, though it is more complex to use. Both tools work best if the drive has not been written to since the deletion — every new file written can overwrite the space where your deleted file lived.

Why Recuva cannot be updated to support Ext4

Recuva is maintained by Piriform (now part of Avast), and they have chosen to keep it Windows-focused. Adding Ext4 support would mean rewriting large parts of the tool to understand a completely different file system architecture. For a tool designed for Windows users recovering Windows files, that is not a priority.

This is not a limitation of recovery in general — it is a limitation of this specific tool. Other recovery tools exist precisely because different file systems need different approaches.

What to do if you are not sure whether recovery is possible

If the drive is still recognized by Windows but you cannot see the files, the file system may be corrupted rather than deleted. In that case, a tool like TestDisk can sometimes rebuild the file system structure and make the files visible again — even on Ext4.

If the drive is not recognized at all, the problem may be hardware (bad sectors, failing controller) rather than file system. No software tool can fix that. A data recovery service can sometimes extract data from a failing drive, but it is expensive and only worth it for critical files.

Before you spend money or time, try connecting the drive to another computer. Sometimes a drive that does not work on one machine will work on another, which tells you whether the problem is the drive itself or the computer.

Frequently Asked Questions

Can I convert an Ext4 drive to NTFS so Recuva can read it?

Yes, but converting the file system will erase all the data on the drive. If you are trying to recover deleted files, formatting the drive defeats the purpose. Convert only if you have already recovered the files you need, or if the drive is empty and you just want to use it with Windows.

Will Recuva work if I use a Linux live USB to run it?

No. Recuva is a Windows program and cannot run on Linux, even from a live USB. You would need to use Linux recovery tools instead, which are designed for that environment.

Is there a version of Recuva for Linux?

No. Piriform makes Recuva for Windows only. If you need recovery on a Linux system, use extundelete, e2fsck, or TestDisk instead.

Can I recover files from an Ext4 drive if I move it to a Windows computer?

Yes, but only with tools that understand Ext4 — not Recuva. PhotoRec, TestDisk, and R-Linux will all work when the Ext4 drive is connected to Windows.

What if my drive shows up as "RAW" in Windows?

A RAW drive is one Windows cannot recognize the file system on. This can happen with Ext4 drives, or with corrupted Windows drives. TestDisk can often rebuild the file system and make it readable again, regardless of whether it is Ext4 or NTFS.
