Over this past weekend, I added a Samsung SP1614C SATA drive to my system. Here is the issue.

Whenever I have the SATA drive connected to the computer, with any IDE drive connected to the primary IDE ports, the computer runs extremely slow. When I remove the IDE HDD, the computer runs extremely fast.

Perhaps it is some setting in the BIOS? I set the SATA to Enhanced to allow for both SATA and IDE access, I tried enabling and disabling IDE Busmaster, and moving around HDDs, etc. I tried removing the IDE contollers and letting Windows detect them again. I checked Device Manager and the SATA drive is being read as UDMA 5, which is normal.

What could be the problem here?
 
I've been doing some research, and I've been seeing that the SATA 1 shares some "channel" with IDE1, thus the slowdown. If I connect the IDE drive to IDE2, there is no noticable slowdown at all.

What gives?
