posting hardware support questions in a gaming forum is a bit off topic
using a sata harddrive requires that you use the sata connector and cable, even if there still is an ide connector in the hd. check your bios setup to make sure the sata controlers are activated. during POST you should see the correct hardware, but if in doubt check in the bios that it is set to autodetect hard drives, or make your bios detect the drive manually.
once you are back in windows, go to device manager and check your hard drive is correctly listed, it should be identified under "disc drives" and under "ide/ata controllers". the sata drivers depend on the chipset used on your mb, and are usually updated with the ms-updates (or you can check for ex the intel website depending on the chipset type and brand)
if all looks correct and you still think it is accessing the harddrive to slowly, use a freeware program like "HDtach" to measure your harddrive read/write speeds (it will plot it out in a nice graph with comparisons of other hardware, and only takes a few min to run)
