Why wont the compter recognize the hard drive?
So 6 months ago I got the famous flashing folder. I took it in to the Apple Store and they replaced the hdd cable. Then last week the flashing folder appeared again. This time Apple told me it was the hard drive. So I bought a 320gb 7200 rpm WD Scorpio Black as computer hard drive. I installed it and Lion in. It worked for about 10 min then it froze again. I've tried resetting the PRAM and reinstalled the hard drive but still the flashing folder. What's wrong?
