hey guys
I own an all-in-one pc that was giving me some issues, i narrowed it down to the HDD of the pc. replaced the hard drive and plugged the old 2TB Western Digital Green into my current pc. it wouldnt let me access the drive without formatting it, so i formatted it. now it onlt displays as a 30GB hard drive even though it is a 2tb hard drive. can someone please tell me how i can access the other 1970GB to see if the hard drive is faulty or not??
thanks
