Hi there ppl!

I dont know if this is the correct forum to ask this, but has im a newbie and all this happened suddently i need URGENT help!!

I went of vacancies on August 10 and left this PC to the care of my father ( big mistake for what i know now .. and when i got home, yesterday, besides the usual mistakes i knew it would have, a much bigger problem occured!

My second hardrive with 35Gb of files stored ( games, movies, programs, web design sites of my own etc ) disapeared!!! Nothing!! When i try to see whats on the drive this message appears: The Disk on Unit D is not formated. Do you wish to format it now?, and it says that its a RAW unit!! What the fu** happened? ((((((((((
My father said that he did nothing to it ( and i belive it ) because he doesnt know shi* of PC´s!
Im really devastated because the collection of files i had toke me years to complete, and i though it was safe on a separated hardrive ((((
