PLEASE HELP! extrnl HD broken? seek error, failed SMART

Hi,
i have a WD elements external HD and i recently dropped it and now it doesnt turn off when not in use and it sounds like the HD is skipping at certain points when i tried to access things.

so i got the diagnostic program from WD and when i try a running a quick or full test it cant finish the test because of "too many bad sectors"

sometimes i can use files or maybe even copy a few over but it doesnt take long for the drive to fail and then i gotta unplug and replug the power source for it to work for a lil while again

personally i dont think its recoverable but i wanted some expert advice before i call it quits on this thing.
also, i read this thread where the guy beat his HD back into working. anyone think i shud try this?

Thanks so much for your patience
