--- Comment #2 from grimlock4h@gmail.com --- It was actually initially noticed after updating to 5.0 RC2. RC3 had came out so I upgraded to that. It was working in 4.21.
Regression is NOT fixing anything. Fixing the bug would be whichever dev broke the ability for WINE to detect a disc drive going back and figuring out what they changed in the relevant code that broke WINE from 5.0 on, or maybe someone who doesn't break functions that have largely been plug and play since the late 1980's, and were working in WINE practically for the project's entire existence.
