Summary

EaseUS data recovery software is a reliable data recovery software for Windows. It fully supports recovering lost, deleted and formatted data from the ext2/ext3 partition, so feel free to download the software for Linux partition data recovery in Windows.

Is it possible to recover data from a Linux partition in Windows

The EXT2 or second extended file system is a file system for the Linux kernel. It is initially designed as a replacement for the extended file system. It is fast enough that it is used as the benchmarking standard. Its main drawback is that it is not a journaling file system. Its successor, EXT3, is a journal file system and is almost completely compatible with EXT2.

The EXT3 or third extended file system is a journal file system that is coming into increasing use among users of the Linux operating system. It is the default file system for the Red Hat, Fedora, and Debian Linux distributions. Why migrate from EXT2 to EXT3? Four main reasons: availability, data integrity, speed, and easy transition.

Although its performance and scalability are less attractive than many of its competitors such as ReiserFS and XFS it does have the significant advantage in that it allows in-place upgrades from the popular EXT2 file system without having to backup and restore data.

The EXT3 file system adds, over its predecessor:

  • A journal
  • H-tree (hashed tree) directory indexes
  • In-directory file types

Without these, any EXT3 file system is also a valid EXT2 file system. This has allowed well-tested and mature file system maintenance utilities (like fsck) for maintaining and repairing EXT2 file systems to also be used with EXT3 without major changes. It also makes conversion between the two file systems (both forward to EXT3 and backward to EXT2) straightforward.

There are three levels of journaling available in the Linux implementation of EXT3:

  • Journal, where both metadata and file contents are written to before being committed to the main file system. This improves reliability at a performance penalty because all data has to be written twice.
  • Writeback, where metadata is journaled but file contents are not. This is faster but introduces the hazard of out-of-order writes where, for example, files being appended to during a crash may gain a tail of garbage on the next mount.
  • Ordered, just like writeback, but file contents are forcedly written into the origins files after its associated metadata, which is an acceptable compromise between reliability and performance, so this is the default.

To recover files from Linux EXT2/EXT3 drive, please follow this procedure:

First, download and install the EaseUS hard drive recovery software on your computer or laptop that is running Windows 10/8.1/8/7/XP/Vista, and then make sure that the Linux hard drive partition is correctly connected. Next, please refer to the three steps for a successful Linux data recovery.

Step 1. Launch EaseUS Data Recovery Wizard.

Since it's on Windows, the Linux drive partition will be recognized as 'lost partition' with no label or drive letter on it. Select the Lost Partition Files and click the "Scan" button.

Step 2. EaseUS Data Recovery Wizard will start a scan once you have clicked the button. Wait patiently during this process.

Step 3. Recover wanted data from the ext2/ext3 drive.

You can find wanted data by clicking Deleted files, Filter or Extra Files. select found data and click the "Recover" button to recover lost ext2/ext3 data.

Caution: Saving the file(s) to the partition or drive from where you are recovering data may result in data overwriting, which will result in a permanent data loss!
