update: it decided to just work again o0

had to reinstall windows 7 today so i had to overclock the usb port for my wmo again. i followed these commom instructions: http://www.ngohq.com/news/15043-how-to-increa...a-7-a.html
i did not realize my external hdd was still connected and running and now that i want to use it, it does not work anymore. meaning that windows (or linux for that matter, tried it with my laptop aswell) does not even recognize it as a hdd anymore. it shows up as an unknown device and i cant install any drivers for it.

is there anything i can do? what did most likely happen?
would be really bad if the data was lost :(

edit: its a WD2500BO14 and worked like a charm with overclocked usb ports over the yeas under xp
