ATA on hard drive

Me again! I have an older DFI MxBoard capable of ATA66 and a WD JB80 Gig
Caviar HD. On the same cable is aCd-Writer and on the secondary is a Cd-Rom.
I remember when I installed this drive I couldn't even get the PC to
recognize it. This was months ago. Then I realized that the drive was
factory defaulted to ATA 100 - faster than my MxBoard could handle. I used
their utility program to step it down to 66. Now I know in the post screen
it said 66 for the past several months.
A few days ago, I slaved this drive on a another PC to transfer files. My
drive has three partitions, one being 40 Gig. I couldn't figure out why the
other PC could only see the first two partitions. So while I troubleshot the
problem, I stepped it down to ATA 33 again. It still didn't work. Then it
dawned on me that this even older PC couldn't recognize partitions bigger
than 32Gig.
No matter. Anyway, I forgot to step my drive back up upon bringing it back
to my PC until this morning. So I used the DLGUDMA utility from does to do
this. It successfully acknowledged the increase. Problem is, it is still
showing up as 33 on my post screen.
I am using WinME and I have tried setting my BIOS to LBA and AUTO. DMA is
also lchecked in Device manager.No change. What am I doing wrong?

I just figured it out. The Cd-Rom that was on the same cable was slowing it
down. when I removed it, the post screen showed UDMA/66. This brings me to a
follow-up: The cd-burner is a master on the secondary cable and there is no
slave. It posts as ATA/33. This unit is virtually new. Do optical drives
normally run at the transfer rate? Dma is enabled in windows and again, BIOS
is set to auto. Yeah, I have an 80 pin cable..
