I recently bought a Lite-On drive (rebadged to Sony CRX220A1).
I’ve been doing some tests with CD Doctor and I’ve found that in a lot of cases the drive spins down during the test, then spins up and carries on.
The strange thing is that there seems to be no pattern. eg it might happen with very good quality media and return very low c1 errors and no c2 errors, or it might happen with bad quality media returning similar error levels, or it might happen with bad quality media returning c1/c2 off the scale.
It doesn’t seem to matter what the read speed is set to (Using e.g CD Throttle), what kind of media is used, what speed that media was burned at etc. It also doesn’t seem to be heat related as it can happen soon after power-on, when the drive is reading at a low speed (beginning of the disc) and after extensive testing last night I found that the behaviour didn’t change even after 3.5 hours of burning/testing. (The drive is cooled with an 8cm fan @ 7v on each side anyway).
Btw, I can do a Transfer Rate test 10 times over with Nero CD Speed and it doesn’t spin down no matter what.
Possibly some kind of bug with CD Doctor?
