After looking around on the net, I think that is right.

hmmm... I think rewritable discs are magnetic and they can only be read on
other CD-RW drives or DVD drives.

If the drive has a 1MB or 2MB buffer and is only writing at 2X or 4X, why
does it matter how fast the interface is? Most drives are 2X, which is
something like 300KB/s.. My motherboard supports up to 20MB/s on both of
its IDE channels. So even if the drive is on a shared channel, it'll
still be able to continously write at 300KB/s, right?

ahh.. there is a HOWTO. Good. It lists many different brands and is very
helpful.
