Why does the “Open device failed” window appear during the DVD-Cloner XR for Mac copy process?¶

The "Open device failed" error in DVD-Cloner XR for Mac occurs rarely thanks to the advanced XceedRead™ cross-generation stable reading engine, but when it does appear, it's typically due to drive occupation or compatibility issues.

🔧 Common Causes and XceedRead™ Solutions

Drive Occupation: The optical drive is being used by another process when DVD-Cloner XR attempts to access it
Cross-Generation Compatibility: Older drives may have timing conflicts with modern macOS systems
Resource Conflicts: Multiple applications attempting to access the same drive simultaneously
Drive Communication: Legacy drives may need special handling by the XceedRead™ engine

🛠️ Recommended Solutions
