Imagine this: you're going to access some important documents on your computer. You power on your computer and nothing happens, your hard drive isn't working. Uh oh, before sobbing, there are several ways you can try to retrieve data from broken computer.
Sometimes, it's not the drive failed, but the physical connection of cables that connect the drive with computer's motherboard. Therefore, you should make sure the data and power cables are firmly connected on both ends before you look for a data recovery tool. Once you have made sure the connections are OK, boot your computer again. If failed, keep on reading.

What happens if your drive is not even being detected by your computer? Or your computer can see the drive, but just hangs when you try to access it? What about if the drive is completely dead and won't even spin up? That may be hardware issues. You should hire a professional technician to diagnose and fix a broken computer with new hardware and get back your data. By the way, it's pretty expensive. Anyway, squeeze your dollar.
