DiskGenius 6.2.0.1821 Update: Disk Speed Test, Windows Boot Repair, and More

Test Your Disk Speed Right Inside the Software

We've added a disk speed test feature. You can now benchmark the read and write performance of your drives without leaving DiskGenius, which means one less tool to install.

It works with both hard drives and SSDs, and the results are straightforward ("Disk" – "Disk Speed Test"). Got a new drive and want to make sure it's performing as expected? Suspect your SSD has slowed down after a couple of years of heavy use? These are the kinds of situations where this feature comes in handy. You open one piece of software, run the test, and you have your answer.

There's a related improvement in the bad sector detection window too. During scanning, you'll now see a real-time read speed indicator alongside the usual progress and bad sector count. If the speed drops sharply at a certain point, that's a strong signal something is physically wrong with the disk. It adds a useful layer of context to what was previously just a pass/fail scan.

Fix Boot Problems Without a Windows Install Disk

Startup failures are among the most frustrating problems a user can face. A blue screen, a restart loop, a "No boot device found" message, the system stuck at the logo indefinitely. The causes vary. A failed update, corrupted boot records, an accidental change to the partition table, a multi-boot setup gone wrong. The result is always the same: you can't get into your system.

The typical fix involves a Windows installation disk or a WinPE bootable drive, followed by command-line work with tools like bootrec or bcdedit. If you happen to have the right media on hand and know what you're doing, it's manageable. But many users don't, and a wrong command can make things worse.

This update introduces a Windows boot repair and conversion feature ("Tools" – "Windows Boot Repair and Conversion") inside DiskGenius. This feature has a graphical interface for diagnosing and fixing boot issues, so you don't need installation media or command-line expertise. For IT professionals who regularly troubleshoot startup problems across multiple machines, this should prove especially useful.

Resume Interrupted Sector Copies Instead of Starting Over

Sector copy reads data from a source disk one sector at a time and writes it to a destination. It's a fundamental operation for data recovery and disk migration. The problem is that when the source disk has bad sectors, the process can grind to a halt. A sector that can't be read means the whole operation stops.

Previously, if that happened, you were back to square one. For a disk with many bad areas, you might need to restart the process several times, each run spending hours re-reading sectors that had already been copied successfully. It was wasteful and frustrating.

Now you can stop the task, adjust the number of bad sectors to skip, and pick up where you left off. Say the copy stalled after hitting 100 bad sectors. Change the threshold to 200 and resume. No need to re-process the parts that already worked. For anyone trying to pull data off a failing drive, this saves a lot of time.

Two TRIM Improvements for SSD Users

SSD write performance tends to decline over time. It's a natural consequence of how NAND flash memory works. TRIM is the mechanism that helps counteract this: the operating system tells the drive which data blocks are no longer needed, and the drive uses that information to clean up internally and maintain performance.

This release adds TRIM support in two places.

The first is in the format dialog. There's now a "TRIM Optimization" checkbox. Format an SSD with this option enabled, and the drive will run a TRIM pass alongside the format. Think of it as a tune-up at the same time as a clean slate.

The second is in the cloning workflow. Before a partition or disk clone begins, DiskGenius now automatically runs TRIM on the target drive. The destination starts from the cleanest possible state, which means better write efficiency from the moment data starts flowing in. If you've just bought a new SSD and are cloning your old system onto it, this happens in the background with no extra steps required.

BMB21-2019: A New Data Erasure Standard

Organizations that deal with classified or sensitive information need to be certain that data on retired storage media is truly gone. A standard format or file deletion doesn't cut it. The data is still recoverable with the right tools.

DiskGenius has supported international erasure standards like DoD 5220.22-M and the Gutmann method for some time. In this update, the "Erase Sectors" feature adds BMB21-2019. Government agencies, defense organizations, and enterprises operating under domestic compliance requirements now have another standard available within the tool they already use.

Restore a Single Partition from a PMFX Image

PMFX is DiskGenius own disk backup image format. In the past, restoring data from a PMFX image that contained multiple partitions meant restoring the entire image, regardless of how much of it you actually needed.

That's changed. You can now select and restore an individual partition from a PMFX image file. If you backed up a 500 GB disk with four partitions but only need data from one of them, you no longer have to write the full 500 GB to your destination drive. Pick the partition you want, restore just that, and you're done.

Smaller Changes That Add Up

A handful of other improvements round out the new feature set:

• In the Quick Partition dialog, pressing 1, 2, 7, 8, or 9 on your keyboard selects the corresponding partition count. It's a small shortcut, but it removes a mouse click from a very common workflow.
• Volume labels can now be chosen from a preset list instead of typed manually. For users who apply standard naming conventions, this is a welcome convenience.
• The sector editor's hex search now accepts a "not equal to" condition, denoted by a "!" prefix. Useful when you need to locate data that deviates from a known pattern.
• Capacity values throughout the interface now show two decimal places by default.
• Dialogs for long-running operations now have a minimize button, so you can tuck them away and do something else while you wait.

Broader File System and Recovery Support

ReFS and EXT4 support have both received attention in this release.

ReFS, Microsoft's newer file system, is designed for data integrity and automatic repair. It's common in Windows Server setups and some Windows 10/11 environments. EXT4 is the standard file system for most Linux distributions. If your workflow involves both Windows and Linux, or you regularly move data between different systems, these improvements will make DiskGenius more reliable in those scenarios.

On the data recovery side, the recover-by-type function now handles HIF and MP4 formats more effectively. HIF is a RAW image format used by certain camera manufacturers. MP4 needs no introduction. As both formats become increasingly common in users' photo and video collections, better recovery support translates directly into more successful outcomes. The file recovery engine has also been updated to better handle unusual data structures, expanding coverage for edge cases that previously might have been missed.

Bug Fixes

Several known issues have been resolved:

• The file system type in the Quick Partition dialog would revert to NTFS after being changed to exFAT or EXT4.
• Unicode string searches in the Sector Editor produced inaccurate results.
• Adding multiple disks in the Erase Sectors feature could trigger exceptions.
• Incorrect "insufficient target space" errors appeared in some cloning, backup, and restore operations.
• Folder modification timestamps were not preserved when copying files from ReFS partitions.
• Excel-format reports with more than one million rows could not be opened. This affected features like file copying and bad sector checking.
• The exclude-folder dialog was empty when backing up a partition to an image file.
