What fails on the AppleCD 300s (caddy)?
Posted by: eraser on 2025-11-09 13:05:56
I have 2 Apple CD300 drives that refuse to read discs. For diagnostic purposes I can swap in a known-good recapped controller board and the drive will take the disc, seem to spin up, then eject it. Since I can rule out the controller as the culprit, what else might be bad on these drives? Laser diode?

Could just be a dirty laser.. I've had at least a couple that needed that.

Try inserting the caddy with a bit more “umph”…. That’s made these more reliable for me.

Weak laser, choice of media type and also check the belts inside if loose/stretched.
