My LG-H55N went crazy today. It was using the 1.03 firmware update with MCSE patch to remove ripguard since December 10, and had worked generally OK. But today it appeared to lose the ripguard and was slow to rip discs and very slow/unreliable burning. When trying to burn a disc at 4x it could only manage 1.5x speed and the device buffer was fluctuating wildly. Naturally I restarted my computer and cleaned up the op system, including a reinstall of my burning software ImgBurn. But that didn’t help. I verified that my computer was OK by burning a disc with my other drive on that channel (a Lite-On), so something appeared to be wrong with the LG. I feared that it had gone south for the winter.
I never liked the 1.03 update because it turned the drive into a noisy creature, where formerly it was fairly quiet. Even when playing a DVD movie, it revved up like it was trying to read at 16x, which is of course unnecessary! So I had a good excuse to revert to the 1.02 update, MCSE patched to remove ripguard of course, which had worked fine for four months prior to trying 1.03. To make a long story short, things are back to normal and the drive works OK again with the 1.02 firmware. I see no reason to change it again.
