|How do you know the drive is rotating too fast? Is there a dramatic change from the way it used to sound? Are you using any stick on labels? |
If the drive is old the spindle bearing may be worn and that could cause vibration, which would make more noise. I doubt the drive is rotating any faster than it should. If the bearing is worn the laser may not be able to read the tracks correctly.
So, most likely you may need to replace the drive.
