I use a Freeagent 500gb HD with my mac and have a lot of my files on it. I have a lot of the files on it backed up however I also have a number of files that aren't backed up on it. I plugged it in the other day and nothing happened, the light didnt come on or anything. The plug is fine and i tried using another adaptor but still nothing. Is there anyway I can get the files off the HD even though its not connecting to the mains power supply? Any help would be greatly appreciated.
