Few days back, my hard drive stopped working properly. My computer will work for sometime, then it will freeze. I bought a new hdd and installed it my in my pc. The problem still existed. Actually, it was because of a faulty RAM. I removed that ram chip and now my pc is working flawlessly. I had opened my dead hard drive(i thought it was dead but it was alright) to see how it looks from inside.. And now my computer is not detecting it. I want to know if i can get it working again.
Hard drives should only be opened by professionals in clean room conditions. You've probably ruined it. If you want the data back you'll probably have to send it to a professional data recovery company. Good luck.
