And the GD-ROM drive IS fundamentally a CD drive and was designed to be compatible with CDs. In fact, with custom firmware a desktop CD drive can read a GD-ROM disc. I've read some arguments on-line that the high failure rate of Dreamcast drives is actually due to the GD-ROM format itself.

NO. The data read is out to in on a GD-ROM reader vs in to out on CD readers. My earlier post points out as well concerning different sized discs will have different pit sizes which do affect how a laser needs to adjust how it reads.

A GD-ROM drive is a CD-ROM drive with some altered motor routines. That's pretty much it. Demonstrate otherwise or be gone!
