How to Fix Errors in DiskGenius Pro: A Troubleshooting Guide

DiskGenius Pro is a powerful utility for data recovery, partition management, and disk cloning, but like any advanced software, it can encounter specific errors during critical operations. These issues often stem from corrupted partition tables, bad sectors on the storage media, or system permission conflicts within Windows. This guide addresses the most frequent technical setbacks users face in 2025 and provides actionable solutions to get your drive operations back on track.

Common Errors

• Partition Table Problem Report: Detects consistency errors like "Ending Parameters Overflow" or "GUID primary partition table damage" upon startup.
• Read Sector Error (Error 23/CRC): Occurs during bad sector scanning or cloning, indicating physical or logical read failures.
• Error 0xc0000005: An "Access Violation" crash preventing the application from starting or completing a task.
• Error 21: The Device is Not Ready: A connection or driver timeout preventing DiskGenius from accessing a specific drive.
• File or Directory is Corrupted and Unreadable: Prevents file access due to MFT (Master File Table) or file system damage.

Fix 1: Partition Table Problem Report

This error typically appears immediately when you open DiskGenius. It indicates that the partition table data (MBR or GPT) does not match the actual disk geometry, often caused by improper shutdowns or previous failed resizing attempts.

1. Locate the Partition Table Problem Report window that pops up automatically.
2. Click the Correct button for each error listed; DiskGenius will attempt to mathematically fix the cylinder/sector alignment.
3. If the window does not pop up, go to Tools > Check Partition Table Error to manually trigger the scan.
4. After correcting, click Save All in the top-left toolbar to write the changes to the disk.
5. Reboot your computer to ensure Windows recognizes the corrected partition boundaries.

Fix 2: Read Sector Error (CRC Error)

When you see "Read Sector Error" or "Data Error (Cyclic Redundancy Check)," it usually means the software hit a bad sector on the hard drive that it cannot read. This often stops cloning or recovery processes.

1. Cancel the current operation and select the problematic disk in the left sidebar.
2. Go to Disk > Verify or Repair Bad Sectors.
3. Click Start Verify to scan for damaged blocks (marked in red).
4. If bad sectors are found, back up any accessible data immediately.
5. Click Repair only if you have a backup, as this destroys data on the bad sectors to map them out.
6. If cloning failed, restart the clone tool and check the option to Skip Bad Sectors to prevent hanging.

Fix 3: Application Error 0xc0000005

This is a Windows system error indicating a memory access violation, often caused by Data Execution Prevention (DEP) blocking DiskGenius or corrupted driver conflicts.

1. Right-click the DiskGenius icon and select Run as administrator to ensure full system privileges.
2. If the crash persists, press Win + R, type sysdm.cpl, and press Enter.
3. Navigate to Advanced tab > Performance Settings > Data Execution Prevention.
4. Select "Turn on DEP for all programs..." and click Add.
5. Browse to the DiskGenius installation folder (usually C:Program FilesDiskGenius) and select DiskGenius.exe.
6. Click Apply and restart the application.

Fix 4: Error 21 (The Device is Not Ready)

This error means DiskGenius can see the drive letter but cannot communicate with the hardware. It is common with external USB drives or drives with corrupted drivers.

1. Close DiskGenius and unplug the USB drive.
2. Plug the drive into a rear USB port (directly on the motherboard) rather than a front panel hub.
3. Press Win + X and select Device Manager.
4. Expand Disk drives, right-click your drive, and select Uninstall device.
5. Restart your PC; Windows will automatically reinstall the driver upon reboot.
6. Launch DiskGenius again to see if the disk status has changed to "Online".

Fix 5: File or Directory is Corrupted

This error prevents you from opening files within the software. It usually points to a damaged Master File Table (MFT) on NTFS drives.

1. Select the corrupted partition in the DiskGenius interface.
2. Click the Files tab to see if data is visible. If not, click Load Current Partition Intelligently.
3. If files appear, right-click them and select Copy to... to save them to a different healthy drive immediately.
4. Once data is safe, right-click the partition and select Format Current Partition.
5. Choose NTFS as the file system and click Format to rebuild a fresh file system structure.

Prevention Tips

• Always use "Safely Remove Hardware": Never unplug a drive while DiskGenius is scanning or resizing partitions.
• Connect to UPS: unexpected power loss during partition resizing is the #1 cause of partition table corruption.
• Regular Surface Scans: Run a "Verify Bad Sectors" scan once every few months to catch drive degradation early.
• Close Conflicting Apps: Shut down other disk-heavy applications (like torrent clients or virtual machines) before launching DiskGenius.

When to Contact Support

While DiskGenius can fix logical errors, it cannot repair physical hardware damage. You should contact a professional data recovery service if you hear clicking, grinding, or beeping noises coming from the drive. Additionally, if the drive is not detected in the Windows BIOS/UEFI at all, software solutions will not work, and you will need hardware-level intervention.
