Ok I'm kind of a tech noob so please bear with me. I just completed my first build (http://pcpartpicker.com/user/slayed1234/saved/qywj4D). It worked perfectly for a few days until I crashed it and did a hard reboot. After doing so I noticed that my hard drive which had previously read "994gb remaining" now reads "98gb remaining" In the BIOS it still comes up as a 1000gb WD drive.
It's a western digital Blue 1TB.
Please Help I don't know what too do. I tried googling the problem but all the tools people recommend refuse to work on windows 8.1. I tried reformatting the drive (too no avail), checking too see if there was any un-partitioned data (there isn't), and also tried using WD's support portal (it's a nightmare).
Any help would be greatly appreciated thank you!
