Awesome new patches
I had the same error when I tried to make the patch myself (unsuccesfully). I reverted the files and the error disappeared, I re-tried to make the fix myself and the error came up again. Finally I used the ifcaro portal 2 fix and have never seen that error again.
I'm not sure the portal 2 error is related to hdd issues.
Below is the photo I took of it (is the image working?)
