Yeah, looks like it's gone. Data Recovery is the probably the only way. Very expensive and not worth it unless you have some reeaaally important data on it, like nuclear launch codes
.
P.S: You can try plugging it into a Linux box and give it a try sometimes. I've recovered an entire hard disk (a few pins connecting to the IDE cable were broken) successfully using Linux. It'll throw up a bunch of errors, but I managed to copy over 8GB of data, whereas Windows wouldn't even detect the disk. Mostly won't work if it's NTFS though.
