Is this a problem?

I don't have my IDE drives described as SCSI, but I don't have the NVIDIA IDE controller driver installed. I'd guess that's why yours show up as SCSI.

NT and XP do treat IDE as a type of SCSI, although the standard IDE drivers built into XP don't show up as SCSI. Every IDE add-in card, and secondary controller chip on the motherboard, that I have seen, shows up as SCSI. I guess Nvidia must have implemented their controller driver so it shows up likewise.

Looks like you have 5 SCSI devices. What kind of mother board do you have?

I'm informed that IDE (or ATA) has a similar command set as SCSI, and that Serial ATA is even closer. I recall reading on the WD site years ago, that they originally intended to make IDE a SCSI interface, but they could not get cooperation and information from companies already making SCSI devices, so they devised their own version. People may not know this, but WD made HD controllers and controller chips, but not HDs, before IDE was devised. One of WDs original claims to fame was the first integrated circuit floppy disk controller chip, which was the key to making floppy disks an affordable mass storage device for the first home computers. That was way before HDs were used in home computers, and way, way before the IBM PC (from which standard x86 computers are decended.)
 
Everything is not running fine. The hard drives seem ok to me, but the DVD-Rom will sometimes refuse to close after opening and when you insert a DVD it will not read, it will just endlessly seek and never find anything, and you have to reboot to get it to read it. Sometimes the CDRW will have trouble reading and requires a reboot.

I will benchmark my hard drive and report back.
 
About the HDDs being detected as SCSI, I have the same thing on my 2 computers with PROMISE ATA66 (one is ATA100) controllers). About the CD-ROMS, try swapping drives. I really don't know though.
 
I rolled back the IDE driver to the original Microsoft one and now my DVD-ROM acts normally again.
