How to Recover an EXT2 EXT3 or EXT4 Partition from Windows

TL;DR:

Recovering an EXT2, EXT3, or EXT4 partition on Windows requires third-party Linux-compatible software, such as Recoverit Linux Data Recovery, to scan the unreadable drive and extract files to a separate physical storage device.
    ● Ignore any Windows prompts to format the RAW or unallocated drive, immediately stop using the affected disk, and never save recovered data back to the original Linux drive to avoid overwriting files.
    ● Recovery of deleted files is highly restricted on SSDs due to TRIM activity, and extracting data from encrypted Linux volumes strictly requires the password or recovery key beforehand.
    ● For unstable drives or missing partitions, create a sector-by-sector disk image first and run a full-disk deep scan rather than targeting only visible volumes.

Recovering an EXT2, EXT3, or EXT4 partition from Windows is possible, but Windows does not natively read Linux file systems. Linux partition recovery on Windows usually requires a tool that can scan ext-based partitions without writing to the source drive.

Recovery results depend on partition damage, formatting history, SSD TRIM activity, and whether new data has overwritten old files.

Step 1
Connect the Linux drive to Windows in read-only conditions if possible. Stop using the affected disk immediately. Do not create new partitions, do not format the drive, and do not save anything to the same device.
Step 2
Check whether Windows detects the physical disk in Disk Management. If the disk appears with unallocated space, RAW space, or an unknown partition, the partition structure may be damaged but data may still exist.
Step 3
Run a recovery scan with software that supports EXT2, EXT3, and EXT4 data recovery. Select the whole disk if the Linux partition is missing. Select the existing ext partition if the partition is visible but files cannot be accessed.
Step 4
Review found files and folders before recovery. File names, paths, and folder structure may be partially restored if filesystem metadata remains intact. A deep scan may be needed after formatting or partition loss.
Step 5
Recover files to a different physical drive. Never restore recovered data back to the original Linux disk. Saving back to the same disk can overwrite remaining recoverable data.

Common Issues and Fixes

Windows asks to format the drive: likely cause is unsupported ext filesystem; fix is to cancel the format prompt and scan the disk with Linux-compatible recovery software.
Partition shows as RAW or unallocated: likely cause is damaged partition table or filesystem metadata; fix is to scan the entire disk for lost partitions and files.
Files are found but cannot open: likely cause is partial corruption or incomplete recovery; fix is to recover another version, use a deeper scan, or check file integrity after export.
SSD recovery fails after deletion: likely cause is TRIM; fix is limited, because deleted ext data on SSDs may be cleared quickly and may not remain recoverable.
Drive disconnects repeatedly or makes unusual sounds: likely cause is physical failure; fix is to stop repeated DIY attempts and consider professional diagnosis.

Quick Tips

EXT4 partition recovery from Windows is usually easier when the drive is still detected with correct capacity.
Encrypted Linux volumes usually require the password, recovery key, or another valid unlock method before file recovery is possible.
NAS drives and Linux system disks may contain multiple ext partitions. Scanning the full disk often finds more results than scanning only one visible volume.
If partition recovery is the goal, creating a sector-by-sector image first can reduce risk on unstable drives.

Note:

Recovery of overwritten files is usually limited. Recovery from physically damaged drives is also limited without hardware-level repair.

Protip:

Avoid formatting a Linux partition from Windows. Scan the original disk or a sector image before making file-system repairs.
