I attached a Western Digital Cavier Blue 500G hard disk
(WD5000AAKS-65TMA0) to the same motherboard. AHCI worked faultlessly.

So the problem was the Seagate 7200.10 250G SATA hard disk (ST3250620AS).

SATA modes should be standard among all hardware devices....I still could
not be sure whether it's a motherboard problem or not.

This query omits whether the OP verified the BIOS is set to enable
both SATA and PATA hard drives.
