I have an Intel motherboard with the 865 chipset. For
some reason, Intel doesn't support the ATA-133 interface,
only the 100 and 66.

I overlooked this part when I bought my hard drive and
cables. I bought an ATA-133 hard drive and ATA-133
cables.

So far, it is working. It seems to be backwards
compatible. Things seem a little slower than they used to
be though. Most noticeably from my CD-RW/DVD drive. It's
52x32.52/16x and the transfer speeds seem noticeably
slower than in my old system with older parts. Shouldn't
be happening I think.

The plan is to eventually use the ATA-133 Hard Drive for
extra storage and hook up a S-ATA drive for my OS and
applications.

My question is, is there a difference in the cabling that
would slow down transfers with mismatched interfaces?
ESPECIALLY from my CD drive. Anybody experienced
something like this?

Yes, I am writing this before I've tried different
cables, but I'm sitting here at work kind of hoping to
get some input.

Thanks in advance :)
