I received a new power supply and vga in the mail today. When done installing them, I powered on my comp and it said "insert bootable media". I checked everything out, and it turned out I had the sata power cable plugged into the wrong hole.... Google says that when there's electrical damage, it's usually not inside the hard disk case, which makes me imagine that I can still salvage it. How would I know that the control board, and not the platters themselves, is damaged? I didn't find any smoke when I powered on, but I can't hear any sounds from the hard disk when I power it on.
I need a better opinion than what google has to offer! Advice please!
