What kind of motherboard is it?
You might have to go into the BIOS when the computer boots and set the SATA mode to enhanced mode. This will make both the SATA and ATA work together. I had some problems when i switched my computer from ATA to SATA, and wanted to keep the IDE drive in at first to transfer data. I ended up switching that setting and was ok.
This setting should be somewhere in the advanced settings, and i believe onboard devices under sata controller.
Good luck!
