Some people have issues with Black Ops online since its latest update, lags enough that isn't even playable. It only effects some drives. This fix does not solve this issue as it effects rev19 as well. If you have issues with that I suggest trying hermes 224[57]. I have a wd green drive in an external case and it ran fine, but when I switched to a wd passport I had to switch the cios I was using to get it to work correctly again. There must be something else in waninkoko's cios running amuck.
