Default Drives show as SCSI but arn't

Ok, I got a new SATA HDD for my rig. Well, I was having all kinds of trouble getting my rig to recognize the drive after the initial windows setup.

Finally, after all else failed, I set BIOS to boot from SCSI instead of SATA. Bam! Fixed the problem. Windows finished installing and I got my rig up and running. I benched my system with norton performance test, thats what I use to give a basic baseline of improvements since I can compare results for a broad range of things from all of my previous setups and configs.

Now, I have a lite-on CDRW and an NEC DVDr/w, both are being shown as SCSI drives under the device manager. They are both on IDE 0. I am wondering if this is affecting performance in anyway, such as DMA? I had an issue with DVD shrink which I never had before, I have solved it, but its a work around.

Do ya'll think this is a problem? If so how do I solve it?

Thanks in advance.

I have this on my Soyo KT400Ultra. It has onboard IDE raid controller, so the hard drives on those IDE channels are seen as SCSI. Hasn't caused any problems for me, but I've got that occuring.

As stated in my original post both drives are connected to IDE channel 0. DVD r/w is set as master, CD r/w is set as slave.


Another question, would I see any performance gain by giving them their own channel? Ie. DVD on channel 0 and CD on channel 1?

I don't do much disk to disk, so I figured to save clutter I would throw them together.

sata shows up as scsi for me too. on my mobo bios, when selecting the boot order, when you select scsi it actually has a drop down menu to select sata. guess its in the same category of hardware.

Found the problem!

It was the damn Nvidia IDE driver. I rolled back the driver to the microsoft driver and BAM. Both drives now show up as IDE and they work flawlessly.

Cool that you found the problem, but I wish you had mentioned using those drivers before.
There is a history of those causing problems.

I hope this gets noticed way down here at the bottom of this thread, but since it's a similar issue I'd rather not start a new tread and creat clutter.

Anyway, I have a friends computer that recognizes IDE drives as SCSI after a few days in Windows. The problem first started after a Windows update, and was then corrected by a reformat. However, the drives now read as SCSI again, with basic functionality. The problem is that the DVD-RW drive will not burn DVDs. It will read all media, and burn CD's, however DVDs will not burn, and it has been confirmed that the DVD drive is not defective.

I attempted to change the drivers, but Windows XP Pro refuses to use IDE drivers for the drive. Occasionally, the drive will accept a new driver, but will revert to SCSI upon reboot. The drive registers as IDE in the BIOS.

Any ideas?
