Best Practices for CDI to MDF Conversion

→For CDI to MDF: test mounting the converted image in a virtual drive before burning it to physical media
→Confirm that the file system (ISO 9660, UDF, Joliet) detected in CDI is correctly replicated in MDF
→Check that bootable disc images remain bootable after conversion
→Verify that any CD-text or DVD region metadata survived the conversion process
→Keep the original disc image until you have verified the converted version boots or plays correctly

Troubleshooting CDI to MDF Conversion

!MDF disc image won't mount → verify the conversion preserved the correct file system and track layout
!Audio tracks missing from MDF after converting CDI → check that multi-track disc images include all sessions
!Copy-protected disc image conversion failed → copy-protection metadata may not transfer between formats
!MDF file is larger than CDI → different image formats use different padding and overhead structures
