Hey folks,
I'm troubleshooting a 24 year old CD drive. 1x speed (fast!) It has trouble reading certain CDs (for example, it doesn't read any CD that has been burned from a .iso image) and has a weird little behavior. Here it goes:
When I put a CD in, it starts moving, then stops. Then again, and again, until I put my finger in and give the CD a spin with it. The drive then whirrs into full speed and loads the CD!
Sometimes, even, the CD doesn't spin at all. It only starts to move (and eventually read fine) when I spin it myself with my finger.
What's at fault? The stepper motor, or the spindle is flaky? The CD, when in motion, reads fine - I have a DOS app called "CheckCD" and tested five CDs with no access or checksum errors. The drive has also been thoroughly cleaned and I used IPA to clean the lens - I don't have any silicon grease at hand, but the rails seem well lubricated.
Cheers and thanks for your replies.
