Asus g75vx HDD trashed

[mcscrub]

First off, heres my specs.
Asus G75VX-DS72 Notebook Laptop specs

his is a harddrive issue. I only have access to about 200g of storage. The issue arose when instead of manually deleting files on several partitions, i Opted for a "quick format" option on the said partitions. Something went wrong and the process failed... As a result I lost access to these partitions as storage. These drives cannot be formatted, accessed saved upon..nothing. I tried to reinstall the controllers but i was following instructions from a friend, and now i cant even view these partitions. I jsut want to use my hdd to capacity. and i dont know ehere to begin. Any and all suggestions and advice would be most welcome.> >Regards.
