yep the data i say is gone.
the disk might even be ruined and the housing magnatised. out of all the speakers you could pick a sub woofer is the worst. big high power and unsheilded.
you could try a recovery tool but really they can recover small errors that can be fatal using tricks. but youve created a massive massive errors and the tricks wont work. cant send it off either for some one to strip the data off it cos the data is junk.
your next step i think is put either bin the disk or you could try using it. put it to the bottom of your case away from any other drives! or remove them and only have the ruined one. then format it and put data on it not your family album of snaps that you want to keep put stuff you might not need and fill it if possible. run that disk for say a 2 months like this and periodcaly test it using the windows disk cheaker tool. if at any time it has to recover bad sectors or anything like that bin the disk! usualy disks have errors and thats ok but this is a disk thats had hard punishement and any errors mean it could fataly die any time.
there is also burn in testers that you could use but i think these would give a wrong reading as the data that they check is only on the disk for a max of say 2 mins where as if the case is magnistised it may slowly affect the disk over weeks.
my advice is if you have the patients try cheaking it over say 2-3 months. if not and can afford it bin it. if the data you use is improtant for work or school or pics of loved ones bin it! if your just gona stick play games on is then give it a go worst case scenario is you loose your save point have to reinsatll everything on a new disk.
******BEWARE THOUGH*************
this disk if it is broken is magnatised so will act like a magnet! so dont i repeat dont put it next to another disk! it would be the same as taking the magnet out the sub and putting it inside your pc next to a disk that isnt ruined.
