Engine DJ: drive or library cannot be read
These are general checks, not model-specific compatibility certification. Start at low volume and change one setting at a time.
Secure backups of originals and the library before formatting, deleting or overwriting.
Check in order
- Record Desktop, Engine OS and drive-migration versions; newer databases are not automatically backward compatible.
- Back up originals and library, then check OS drive access and the actual music files.
- Sync a one-track test list, safely eject and test on hardware; distinguish missing audio from database issues.
- Do not begin by deleting Database folders; consult the recovery procedure for the specific version.
- If unresolved, record models, OS/app versions, OUT-to-IN routing, the last responding meter and comparison results in the support note.
Track/USB loading fails
- Preserve drive/originals first and identify hardware/Desktop versions.
Playback works; output/mode differs
- Separate the playing layer, standalone/computer mode and physical outputs.
If unresolved
Record hardware models, OS/app versions, the last responding meter and test outcomes for official support. Do not infer hardware failure or a purchase requirement from unverified checks.
