That is what I was wondering about, was bad sectors, but also, while 120 gig of free space seems like a lot, it is right at 10% of the drive's size. Windows gets weird about that. Where do you have your swap file for Windows? You might consider adding another hard drive, or replacing the 1TB drive with a new, larger one. Which hard drive holds your F partition? Or is it a separate hard drive? Is that the restore partition for your computer? If so, that error is possibly a misinterpretation of the data by Windows, and might not be bad sectors.
