I was tired around 12:30 AM last night, and accidentally placed a DVD on top of another one already in the DVD-ROM drive.
The drive made a terribly loud scraping noise (the top disc came out scratched all around the circumference near the outer edge).
I ejected it after about 10 - 15 seconds.
The drive seems to work alright, luckily and amazingly, but I wonder if any damage to the motor or other mechanisms may have occurred.
I may never find out, but I was wondering if someone who knew how much clearance a LiteOn LTD163 has, might know if any physical or mechanical damage would or wouldn't have occurred.
