-E Set cdrom speed. This is NOT necessary for regular operation,
as the drive will automagically switch speeds on its own. But if you want to play with it, just supply a speed number after the option, usually a
number like 2 or 4.

adjusting cdrom speed is really NOT a good idea, it may not read data/ or play music CD's properly!!
any other opinions out there??

I tried to install Slack 8.1 on an old Gateway box with an NEC 8x CD-ROM and the installer hung due to a hard drive error. When I rebooted the computer the CD-ROM drive ran much slower, and the only way I could get it to return to full speed was to unhook the drive from the computer and let it sit overnight to reset itself. If I try again and I get the same error, I'll attempt to use hdparm.
