I tried that long ago, when that drive was on "active duty" As with all LiteON readers I had, it has no external way to lower the reading speed. I did find a hacked bios set with plenty of different "top speeds" bios versions, some of which are low for silent operation. Well, the drive certainly had its merits, for one, it would read a DVD+R5 with 16x. But you certainly had dive bomber acoustics all day. :bigsmile:
Edit: To avoid confusion, the lack of regulation applies to DVD disks. CD speed can be set, iirc.
