USB drive missing in computer or rekordbox
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
- First check Finder/File Explorer for the storage drive; distinguish storage detection from DJ-controller detection.
- If absent in the OS, compare another direct port; do not initialize a drive without verified backups.
- If visible in the OS, inspect rekordbox Devices and verify supported formats for both software and target player.
- Check read-only state, free space and disk errors; copy important data elsewhere before repairs.
- If unresolved, use the support note below to record hardware, OS/app versions, last responding meter, tests and outcomes for official support.
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.
