Just wanted to let you know, I have exact same problem plus 2 recovery partitions after upgrading to windows 8.1, cant defrag any of my drives, I get parameter incorrect.
Whatever you do , do NOT run checkdisk.
It stays in the infamous loop stuck at 10% ,it completely buggered my computer as when I got out of it low and behold my C.drive had been changed to an empty drive with no accessible operating system.
So I had enough and went back to windows 7 until I get AN IMAC.
