I have a Seagate free agent go 500gb that just quit working. I was trying to watch a movie off of it so I decided to plug it into my ps3. It didn't work. Said it was a unknown device. So I plugged it back into my laptop to do some more transferring and now all it does is blink. It don't show up on my computer now. It does make a noise when plugging it on but that's it.
I'm assuming it could be in some sort of fail safe mode but all I know is that my wife is going to kill me if I can't get the pics off of it!
