After reviewing various reliable sources and community feedback, here are the most commonly recommended fixes for the "SCSI Medium Error" in MakeMKV:
Check for disc damage: Even minor scratches or dirt can cause read errors. Clean the disc carefully with a microfiber cloth and a cleaning solution designed for optical media.
Use a different drive: Sometimes, the issue is with the drive's ability to read specific discs. Try another optical drive if available. Certain drives handle error correction better than others.
Update firmware: Ensure your optical drive’s firmware is up-to-date. Manufacturer websites often have updates that improve disc compatibility.
Try a different disc: Test with another disc to determine if the issue is specific to the current one or a broader problem with the setup.
Enable MakeMKV debugging: In MakeMKV, go to Preferences > General, and enable "Log debug messages." This can provide more details about what’s causing the error.
Slow down the read speed: Some users have reported that lowering the read speed of the drive can help bypass problematic areas of a disc.
Replace the disc: If the error persists and is specific to this disc, it might be due to physical defects that can’t be corrected, even if they’re not visible.
If none of these solutions work, consider reaching out to the MakeMKV forums where experienced users and developers can provide more targeted assistance. Good luck!
