about 1 month ago i got a new harddrive for my computer. And recently it has today it is acting like I can't write on the disk. I can't install java it says that there is not enough space, but i have 502 gigabytes free. I downloaded super meat boy but couldn't install it. I re downloaded THE BINDING OF ISSAC on steam and it would not launch. And downloaded Warframe and it fails to update DirectX. I can't log into skype because it says that there is a disck I/O error. My computer verfied my harddrive and it said that all of the files that I had downloaded didn't exist or where invalid.

Edit:CPU: Intel i5-2500k at 3.3GHz
