Troubleshooting Common Drive Snapshot ErrorsDrive Snapshot is a powerful disk imaging tool used to create exact copies of hard drives and partitions. While it’s reliable for backups and cloning, users can still encounter errors that interrupt imaging, slow performance, or cause incomplete backups. This article walks through the most common Drive Snapshot errors, their likely causes, and practical solutions you can apply step-by-step.

1) Image creation fails or stops unexpectedly

Common symptoms: process aborts with an error message, partial image created, or the program closes.

Likely causes

  • Disk read errors or a failing hard drive.
  • Insufficient disk space on the target volume.
  • File system corruption.
  • Conflicting software (antivirus, other backup tools) interfering with read/write operations.
  • Permissions problems or running without administrative rights.

Troubleshooting steps

  1. Check free space: ensure the destination drive has at least the size of the used data plus extra room for temporary files.
  2. Run CHKDSK on the source drive:
    • Open an elevated Command Prompt and run: 
      
chkdsk C: /f /r
    • Reboot if CHKDSK requires it.
  3. Test source drive health:
    • Use SMART diagnostics (CrystalDiskInfo, smartctl) to check for reallocated sectors, pending sectors, or other warnings.
  4. Disable third-party antivirus or set exclusions for Drive Snapshot temporarily.
  5. Run Drive Snapshot as Administrator (right-click → Run as administrator).
  6. Try imaging smaller partitions or individual folders to isolate the failing area.
  7. If imaging over a network, copy the image locally first to rule out network interruptions.

2) Image verification fails or reports checksum mismatches

Common symptoms: verification reports errors, or tool cannot validate the integrity of the created image.

Likely causes

  • Corrupted image due to incomplete write or storage medium errors.
  • Hardware issues (bad RAM, failing disk controller, faulty network transfer).
  • Interruptions during the write phase (power loss, system crashes).

Troubleshooting steps

  1. Re-run verification; sometimes transient read errors cause a single failure.
  2. Store the image on a different medium and verify again (another HDD/SSD or external drive).
  3. Check RAM stability using MemTest86 to rule out memory-induced corruption.
  4. Ensure stable power—use a UPS for desktops during imaging jobs.
  5. If using network storage, switch to a local drive to eliminate network packet loss or SMB issues.

3) Slow imaging performance

Common symptoms: imaging process takes much longer than expected.

Likely causes

  • Slow source or destination drives (older HDDs, USB 2.0).
  • High CPU usage or insufficient RAM.
  • Antivirus scanning each file being read/written.
  • Network bottlenecks if saving to a NAS or remote share.
  • Drive Snapshot compression settings increasing CPU load.

Troubleshooting steps

  1. Use faster interfaces: prefer SATA/USB 3.0/Thunderbolt or local SSDs.
  2. Temporarily disable antivirus or add exceptions for the imaging operation.
  3. Lower compression level (if using compression) to reduce CPU load and speed throughput.
  4. Close other disk-intensive applications and heavy background tasks.
  5. If using network storage, test raw transfer speeds and try using a wired gigabit connection or direct-attached storage instead.
  6. Consider imaging in smaller segments or per-partition to better manage throughput.

4) Cannot mount or restore from image

Common symptoms: restore process fails, volume won’t mount, or files are inaccessible after mounting.

Likely causes

  • Corrupt image file.
  • Version mismatch between Drive Snapshot image format and the tool trying to restore/mount it.
  • Permissions or user rights preventing access.
  • Target disk layout mismatch (e.g., different partition table types: MBR vs GPT).
  • Drive letter conflicts or OS-level restrictions.

Troubleshooting steps

  1. Verify image integrity before attempting restore.
  2. Ensure you’re using a Drive Snapshot version compatible with the image file—update the software if needed.
  3. When restoring to different hardware, check BIOS/UEFI settings (AHCI vs IDE), and be prepared to adjust drivers or perform a repair install after restore.
  4. Delete or reassign conflicting drive letters in Disk Management before mounting.
  5. If restoring to a smaller disk, ensure the used data fits; resize partitions in the image if needed beforehand.
  6. For permission issues, mount with elevated privileges or access files via a recovery environment.

5) Drive Snapshot service or driver fails to load

Common symptoms: driver not installed, service error on startup, or the program reports missing kernel driver.

Likely causes

  • Driver signature enforcement blocking unsigned driver.
  • Corrupted or missing driver files.
  • Incompatibility with the current OS version or updates.
  • Security software blocking driver installation.

Troubleshooting steps

  1. Reinstall Drive Snapshot using an installer run as Administrator.
  2. Check Windows Event Viewer for driver-related errors and note the specific driver name.
  3. If driver signature enforcement is the problem, enable test signing only as a last resort, or obtain a properly signed driver from a trusted source.
  4. Temporarily disable security software while installing the driver.
  5. Ensure Windows is updated; some OS updates may require matching driver updates from the software vendor.

6) Errors during differential/incremental backup

Common symptoms: incremental runs fail, or restore requires a full image when it shouldn’t.

Likely causes

  • Broken chain of incremental snapshots (missing base or intermediate increments).
  • Altered or moved image files that break references.
  • Using different software versions for base and increment images.
  • Time/date stamp mismatches causing snapshot metadata confusion.

Troubleshooting steps

  1. Always keep the full-image base and all increments together; do not rename or move files unless you update references in the software.
  2. Use consistent Drive Snapshot versions for base and incremental backups.
  3. Regularly create a fresh full image and start a new incremental chain periodically to avoid long dependency chains.
  4. Document where backup files are stored and how they’re named to prevent accidental changes.

7) Permission/access denied errors

Common symptoms: “Access denied” messages when reading source or writing image.

Likely causes

  • Not running with administrative privileges.
  • Files locked by other processes (open files, VSS issues).
  • Destination location restrictions (network share permissions).

Troubleshooting steps

  1. Run Drive Snapshot with elevated privileges.
  2. Use Windows Volume Shadow Copy Service (VSS) integration to capture locked files—ensure VSS is functioning.
  3. For network destinations, verify share and NTFS permissions for the account performing the backup.
  4. Close applications that may have exclusive locks on files, or perform the backup in Safe Mode or WinPE if necessary.

8) Incompatible or unsupported hardware

Common symptoms: imaging completes but restored system fails to boot on different hardware; storage controller not recognized.

Likely causes

  • Missing drivers for target hardware (SATA/AHCI/RAID controllers).
  • Differences in firmware/UEFI vs legacy BIOS settings.
  • Disk geometry or sector size mismatches (rare with modern drives, but possible with advanced/4K sector or SMR drives).

Troubleshooting steps

  1. Before restoring to different hardware, capture necessary mass-storage drivers and inject them into the restored system or perform a repair/restore in a recovery environment.
  2. Match BIOS/UEFI storage mode (AHCI/RAID/IDE) between source and target where possible.
  3. For boot issues, use Windows repair tools (Startup Repair) or run: 
    
bootrec /fixmbr bootrec /fixboot bootrec /rebuildbcd

    from a Windows recovery environment.

  4. For advanced disks (4K/SMR), consult drive vendor guidance and ensure the target environment supports the drive type.

9) Errors specific to network backups

Common symptoms: timeouts, incomplete images, or slow transfers when saving to NAS or remote shares.

Likely causes

  • Unstable network, high latency, or packet loss.
  • SMB protocol mismatches or authentication problems.
  • NAS device limitations (CPU, concurrent transfers).
  • Firewall or router interrupting long transfers.

Troubleshooting steps

  1. Test network stability (ping, iperf) and switch to wired connections if possible.
  2. Mount the network share with proper credentials and test read/write outside Drive Snapshot first.
  3. Temporarily disable firewalls or adjust timeout settings for long transfers.
  4. Copy the image locally and then transfer it to the NAS to determine whether the issue is with Drive Snapshot or the networked storage.

10) Unexpected file exclusions or missing data

Common symptoms: certain files or recent changes are absent from the image.

Likely causes

  • Exclusions or filters set in the imaging profile.
  • Files modified after snapshot creation or files open with exclusive locks not captured without VSS.
  • Corrupted file tables or directory entries.

Troubleshooting steps

  1. Review Drive Snapshot settings for exclude/include rules.
  2. Use VSS to capture open/locked files.
  3. Confirm files exist and are readable on the source before imaging.
  4. If particular folders are missing, try imaging just those folders or mounting the image to inspect contents.

Practical checklist before running Drive Snapshot

  • Verify destination has ample free space.
  • Run CHKDSK and basic SMART tests on source drives.
  • Update Drive Snapshot to the latest compatible version.
  • Disable or exempt antivirus during imaging.
  • Run as Administrator and, for critical images, use a UPS.
  • Store full images and increments together and maintain a clear naming scheme.
  • Periodically create a fresh full image to simplify restores.

When to contact support or replace hardware

  • Repeated SMART failures, unexplained bad sectors, or MEMTEST errors usually indicate failing hardware—replace drives or RAM.
  • If errors persist after following the troubleshooting steps, collect log files and exact error messages and contact Drive Snapshot support or vendor forums for assistance.
