BD drives have 3 laser diodes (BD, DVD, CD).
Lasers can be fickle in how they read different surfaces, pressed vs. dye, or even between dye types. Normally, if it struggles to read ROM discs, it will completely fail at burnedor blank discs. But not always.
Most optical drives have a limited lifespan, 2-5 years. It's pretty terrible, and makes blank DVD claims of "100 years" look even more ridiculous. I've said it for 15+ years now, optical media is likely not archival, because we won't have any extant drives to read it. VCRs still work after decades, but CD/DVD/BD drives rarely make even half a decade.
I will not eliminate OS issues here, but given how screwy the drive can be, I'd want to test it on another system.
