I have just installed a new LgWH10SL30. The firmware on Diskspeed shows 1.0. I was able to locate the 1.06 update (took a while), upon trying to perform the update it showed that I had the 1.09 firmware, which was the one I was looking for originally. Does the 1.0 that was displayed mean it is 1.09? I see where the firmwares are listed that way for Lg, i.e. 1.0-6, 1.0-9. Sorry if this was overlong or not too clear.
I just got a WH10SL30 too but it came with 1.06. I can't even find the 1.09 firrmware for this drive so I flashed it to BH10SL30 1.09. Found the firmware here http://files.rpc1.org/
