Overview

DiskGenius is a multi-purpose Windows utility spanning partition management (resize, move, create, format), disk/partition imaging for backup, and data recovery from deleted or damaged partitions. That combination makes it a reasonable single tool for someone dealing with a disk problem rather than a planned backup routine.

Its data recovery capability — scanning for lost partitions or deleted files and attempting to recover them — is a meaningful differentiator from pure backup tools like Macrium Reflect or AOMEI Backupper, which don't attempt recovery from an already-damaged or already-deleted state.

The free edition covers basic partition management and some recovery/preview functionality; more thorough recovery (actually saving recovered files past a certain size or count) and some advanced partition operations sit behind the paid edition. Check the developer's site for the current free-versus-paid boundary, since recovery-tool free tiers commonly restrict how much you can actually save rather than just preview.

It's a Windows-only, install-and-run application rather than bootable rescue media, so if the drive with a damaged partition is your only drive, you'd typically need to move it to another machine or use bootable media before running DiskGenius against it.

Key features

  • Partition resizing, moving, creating, and formatting
  • Disk and partition image backup and restore
  • Deleted file and lost partition recovery scanning
  • Bad sector checking and basic disk health reporting
  • Support for common Windows file systems including NTFS
  • Bootable rescue media option for recovery outside of Windows

System requirements

Operating system
Windows 11 and Windows 10 (older Windows releases also supported)
Disk space
Recovered files need destination space on a different drive than the one being recovered
Permissions
Administrator rights required for partition and disk-level operations

How to install DiskGenius

  1. 1. Download from Eassos

    Get the installer from diskgenius.com/download.html.

  2. 2. Install

    Run the installer and approve the UAC prompt.

  3. 3. Attach the affected drive if needed

    For recovery from a drive that isn't your system drive, connect it as a secondary or external disk before scanning.

How to use it

  1. 1. Resize a partition

    Select the partition in the main window and use the resize/move tool, always after backing up important data first.

  2. 2. Create a partition or disk backup

    Use the backup function to image a partition or whole disk to a file before making risky changes.

  3. 3. Recover deleted files

    Run a file recovery scan on the affected partition, then save any files you want to keep to a different physical drive.

  4. 4. Recover a lost partition

    Use the partition recovery scan to search for partitions that have disappeared from Windows, then attempt to restore the partition table entry.

Safety and privacy

  • Download only from diskgenius.com; the tool is a common target for repackaged, ad-bundled mirrors.
  • When attempting data recovery, avoid writing recovered files back to the same drive you're recovering from, to avoid overwriting recoverable data.
Bundled software
The official installer from Eassos's own site does not bundle unrelated third-party offers.
Privacy
Runs locally; check the developer's site for current account requirements, if any, tied to licensing.

Known risks

  • Partition resizing and formatting are inherently destructive operations if misconfigured — back up important data before making partition changes.
  • Free-tier recovery often previews recoverable files but limits how much can actually be saved; verify current limits on the developer's site before counting on it for a large recovery.

What's new

  • Current release series

    Eassos updates DiskGenius periodically with recovery algorithm and file-system compatibility improvements. Check the developer's release notes for the current version.

Pros and cons

Pros

  • Combines partition management, backup, and data recovery in one tool
  • Free edition allows basic partition management and recovery scanning
  • Supports common Windows file systems
  • Includes a bootable rescue media option

Cons

  • Free edition significantly limits how much recovered data you can actually save
  • Partition-level operations carry real risk if used carelessly
  • Interface can feel dense for users only wanting simple backup

Verdict

DiskGenius is a useful one-stop tool when you're dealing with a partition problem or need to attempt file recovery alongside routine backup and resizing tasks. For recovery specifically, check the free tier's save limits carefully before assuming it will fully cover your situation.

Frequently asked questions

Is DiskGenius free?

A free edition exists for basic partition management and recovery scanning, but saving larger amounts of recovered data typically requires the paid edition. Check the developer's site for current limits.

Can DiskGenius recover files from a formatted drive?

It can scan for and attempt to recover files from formatted or deleted partitions in many cases, though success depends on how much the drive has been overwritten since.

Does it work without Windows booting?

DiskGenius itself runs inside Windows, but it also offers a bootable rescue media option for situations where you need to work on a drive outside of a running Windows installation.
