BTC/Top G 8x dual format DVDRW drives no longer detecting CD

I have two BTC/Top G-built 8x dual format DVDRW drives.

The first one is an Emprex drive (1008-something) and the second is an IO Magic Dual Digital Storage 8x dual format DVDRW with 7-in-1 card reader. The IO Magic is a 1008IB.

Both drives initially was able to burn CDRs up to 40x. Now, both no longer burn or read CDs, regardless of whether they are audio, mp3, data, or software CDs. They still can read and write DVDs though.

Has anyone figured out why they are acting up? I'm assuming it's something to do with my computer as I bought another IO Magic and that too did not read/write CDs.

As for the Emprex, it started burning DVDs real slow (the light would alternate red and green). Someone said it was in PIO, despite DMA being enabled. I took this out of my Compaq and put it in my mom's P3 933mhz Gateway computer. She has an 12x DVD-ROM drive, and the Emprex replaced the original 8x CDRW drive that came with her computer.

The Emprex worked fine, reading/writing to CDs and DVDs. It no longer took 2-3 hours to burn a DVD, and the CDRW speeds were fast. Now (within a month of the IO Magic), the Emprex did the same thing as the IO Magic. It became useless as a CD drive.

The DMA thing took care of the Emprex's problem of burning really slow.

Both the drives burn DVDs like normal now (ie 4x takes about 14 minutes). They still don't recognize any kind of CD.

I talked to IO Magic's tech support and they had me update the IO Magic's firmware. That didn't work.

So they had me update something called ASPI drivers. No joy.

Then they had me go to for something known as a Via 4 in 1 to update a chip in my computer called a Via. Still the same...DVD functions (read/write/rewrite) work but CDs don't.

Do any of the mods want to test my Emprex drive? It's currently not being used and I can send it at my cost to a mod if they live in the continental US, especially in Southern California.
