After an idiot hit the "Scan and Fix" button that shows up when I plug in my flash all my data is unable to be accessed. My tech geek father managed to grab one of my folders but the others I still can't at least copy elsewhere. Windows XP will see the folders for a time but then say they are inaccessible; Vista freezes every time I plug it in; the Macs don't even see it; Windows 7 managed to grab that one folder I mentioned. Can anyone tell me how to retrieve my data without spending a fortune -- BEFORE I'm forced to reformat it?
