Nec 3520a problem

Installed my new NEC 3520a . No problems with reading DVD’s.

When I insert a Blank CD no problem either. However when I insert a burnt CD the drive emits an audible grinding noise until it finds the start of the disc which takes around 5 secs. It eventually reads the CD without problems.

Any thoughts ?

Default rotation speed for DVD+R/-R is maximum. When you have data on the disc, the drive will run at max rpm.

Is there a way to slow down the max rpm when reading a CD (not DVD) having data on it since I do not fancy damaging the drive.

You can download AnyDVD from Slysoft.com. Launch AnyDVD and click the Drive tab. Make sure the NEC drive is checked. Now Enable Speed Control. Select Slow & Quiet for Vide DVD, Audio CD, and Other Disc.

You cannot damage the drive with the default rpm setting.
