I recently bought a Pioneer A09XL (Retail, mind you.) and it's being recognized by my computer as a 109 with 1.17 firmware. The guys at the "firmware page" forum told me that this is normal, and that I could verify if my drive was truly an A09XL by running Pioneer's quietdrive utility, to see if it is recognized. I ran the utility and it recognized it, so I suppose my drive really is an A09XL. My question is, I want to update my firmware to 1.40 (I'm supposing that this newer firmware is better than the one I'm using right now. If its not too much to ask, can someone please tell me the advantages of this new firmware?) This will be my first time flashing a drive so I wanna make sure I don't screw up. Should I be using A09XL firmware or 109 firmware? And should I be using the utility included by Pioneer, or is there a 3rd party program that I am better off using to flash with?
