hmm. i remember back in the day when i was trying to read an audio cd in this Lite-On burner. the burner still works great. i just vacumed it and took all the pieces out. it's in my dad's computer and he doesn't use it much, but i can still hear pieces inside. the theory here is this: if it ain't broken, don't fix it.

once when i was trying to read a cd, it exploded inside the drive. i opened the drive and vacumed what i could. the drive still works. i should take it apart since it's way out of warrenty now but as they say, if it ain't broken, don't fix it.
Happened to me just the other day. One month old Lite-on. I put a blank CD in and the machine didn't recognize it as a blank disc. So I took it out, but a different disc in and burned it. Later on I put the first one back in, it spun up and then BANG.
It was SERIOUSLY loud. I jumped out of my seat. The computer is on my desk and I thought it was a gun shot.
I didn't bother to take it apart as I figure it's probably toast.

Where are they getting the 30,000 rpm figure from?
As they found it took a seriously powerful router to get that speed over 25,000 rpm! The spindle motor on a CD drive is not nearly as powerful. Even though the insides of the drive are better optimized from an aerodynamic standpoint, the amount of electrical power required would be far greater than a small PM motor that's used.
If you do the math, reading a cd at single speed on the innermost tracks at 550 rpm would require > 30,000 rpm to achieve the rated speed. But there's a catch. CD's are recorded in a way that one must vary the speed to maintain the same data speed. (CLV) The newer drives (started after 8X) were CAV which meant they were capped on the innermost tracks and would only achieve the absolute max rating on the outermost tracks.
The same is true today with 48X units. Most start out around 16X speed on the inner tracks. This is roughly 8800 rpm. Still very fast but a far cry less than 30,000! The fastest drives begin at 24X (around 13,000 rpm max) which is less than half the seemingly critical mass speed of 30k. 🙂

around $40 is a brand new NEC 3550A dvd-rw on newegg.
sorry to hear about your drive. my bet is that its totally screwed up now, or that it will perform a lot lower than expected.

I've seen videos where people load cd's on dremen tools and launch em - BOOM! 🙂
BUt, yes, most likely your drive is broken or theres some miniscule peice you'll never find that isn't worth risking future disk (if it scratched them)
