CD-ROM Sound and Vibration
==========================
Your computer comes with a 12-speed (12x) CD-ROM drive, one of the fastest speeds available. The 12x CD-ROM drive reads CD-ROM discs very quickly, but because of the drive's high rotation speed, you may hear unanticipated sounds coming from it.
During CD start Up and long searches
------------------------------------
For example, when you insert a CD disc into the CD-ROM drive, you may notice a few seconds of sound that makes you think either the disc is loose in the drive or something inside the computer has come into contact with the spinning disc. This sound may also occur occasionally when the drive scans the disc for data. If you hear it, do not be concerned. The sound is normal and the disc remains undamaged.
During regular CD-ROM operation
-------------------------------
Today's high-speed CD-ROM drives normally cause a certain amount of sound and vibration. However, there are also some cases in which a CD-ROM disc label has artwork that causes the disc's weight to be slightly off-center. Occasionally, this uneven distribution of weight coupled with the high rotation speed of your CD-ROM drive can cause a disc to wobble in the drive and cause vibration. If your CD-ROM drive does begin to vibrate, you don't need to do anything special; continue to use the CD-ROM disc as you normally would. The vibration damages neither the CD-ROM disc nor the computer.
