Hello, I have a brand new computer build with a Hitachi Ultrastar 1TB 3.5" 7200RPM Internal Hard Drive. It has recently changed to RAW and I am unable to install my operating system on it. When trying to install Windows 8, I get to where I would like to save the OS on, however no disk drives appear. When I attempt to load drivers, I can see Local Disk (C: ) is still there and there is an option to format it however I get the error message "Windows can't format C." Likewise, chkdsk in the command prompt yields nothing. I personally only have a complementary laptop but I live in a dorm so finding someone else to hook the HDD is probably possible and I have a 2 year-protection plan on it from Amazon so returning it is not preferred, but also not a problem.
