i just bought a new samsung 320gb 3.0gb/s HDD. unfortunately, i didn't know that my MB only supported SATA-I. i connected the HDD to 2nd sata(primary) slot, turned on my computer, but when i checked my bios it said that it didn't detect any hard drive. so i placed the jumper so that it would run in the 1.5gb/s mode, but it still wasn't detected. i've been trying to look for an answer to my problem for the past few days, but i still can't find anything. can someone please help me? thank you!
