Sony has secretly released a new version of the 3.56 firmware, version 2, which fixes a major bug in the previous release. The bug, which is now fixed, involved user upgraded hard drives showing up as corrupted. Sony silently pushed out the new 3.56 PUP, attempting to cover up the fact that they dropped the ball on the original 3.56 release. It appears to be a common trend with Sony, that quality assurance goes out the window, anytime a new firmware update is urgently pushed out for release by them.
