anyone here know anything about hard drives? i have one that has pretty much fail on me and i need to get all my data off of it. i am computer savvy and have tried everything i can think of. its a 500gb western digital HD, was in an external case(put in by me) and then removed today to put inside my computer that i just built to back up and reformat. tried running check disk, HDD regenerator to no avail. it has a bunch of bad sectors that for some reason cant be fixed. i plugged it back inot the external case and tried plugging it into my macbook but it will not mount it(hehehehe....mount) nor will it repair it. it does spin like its supposed to, no clicking or grinding or scratching noises come from it. i cant lose all of my music or movies or i will be devastated. any help is much appreciated!
