User:Derf/CD Burning Shenanigans

These are my futile attempts to burn patched/homebrew ISOs to CD-R to play on my Turbo Duo. Pressed discs read perfectly fine. I should open an Etsy that sells CD-R coasters.

Media Reflectivity

Note the strength of contrast between the burnt vs unburn areas on the disc.

Pressed disc - Very strong contrast

CMC Pro (Taiyo Yuden) - Strong contrast

Maxell Gold - Strong contrast

Verbatim - Weak contrast

Below are scans of the same discs. Oddly, the pressed disc shows almost no contrast in a direct scan.

Disc Quality Scan using Optiarc

Verdict: This drive resulted in many more errors than the iHAS even when using the same disc, so it likely has a dying laser.

Disc Quality Scan using BENQ

All scans failed with "ILLEGAL MODE FOR THIS TRACK (056400)" error on any discs burned by the BENQ itself, discs burned by other drives, or pressed discs despite burning discs well.

Lessons Learned

• Check what the minimum and maximum speed that the media (disc) reports, and burn at the minimum the media (NOT DRIVE) supports.
• Cross-check Disc Quality scans with multiple drives to make sure the drive isn't the issue. The optiarc here appears to be bad.
