I have a mid 2010 Macbook that won't turn on. I took it to the Apple store, but they were unable to tell me what was wrong. They told me I needed to send it in for repair, but that I should try to get the data off the hard drive first. I took my hard drive out of the computer, and used a SATA cable to try to pull the information off. When I plug the cable in to another computer (a PC), it showed the name of the device, but none of my computer contents came up. Does this mean that my hard drive is bad, or am I having issues because I'm trying to use a PC rather than another Mac?
