In my case I'm using SATA hard disks and IDE DVD/CD rom dirves.
Strangely enough, the system finds the SATA hard disks as /dev/sda and
/dev/sdb, while the optical drives show up as /dev/hdc and /dev/hdd even
though they are IDE drives 0 and 1. I thought that SATA was implemented
AS SCSI in the kernel and the change from /dev/hdn to /dev/sdn was a
result of SATA not the way IDE was handled. I'm not sure how the BIOS
numbers the drives (IE: IDE or SATA first).

How does one tell the differences from real SATA and non-SATA? I liked
hd* and sd* to see the differences. :(

Beside opening the computer and looking inside. ;P Didn't all PATA/IDE
use hd* before the changes? That's what I recalled. I might be wrong.
