Several days after this:
FastFat New Hardware Wizard
up until today....
Last night all i remember doing is installing a game and I played it for a little while (street fighter 4). Then I shut it down properly. When I got up this morning, I was greeted with a black screen with a message saying that the computer has nothing to boot up. I looked in the bios to view the location where it was installed, and it doesnt have a description. Sea Tools told me that the long DST had failed but the others passed.
I hooked it up to another computer through usb and the drive doesnt even show up at all. (cant even access my data). I put my 80gb seagate drive in to test it out and that works. This hdd that suddenly wouldnt be recognized is a 1tb seagate hdd.
So I look inside Computer Management > Storage > Disk Management (windows on this other cpu) and it has the 1tb seagate drive named seagate D:. The file system on it suddenly says CDFS instead of NTFS. The status says healthy. The capacity shows 624mb with 0 free space when it is a 1tb hdd. The original name that the 1tb hdd had is gone.
How in the world could this have happened suddenly and how can I fix this? Also, do you think that the fixboot cmd prompt can fix this?
(P.S. Thanks in advance)
