PowerBook G4 SuperDrive Speed Bump Hack

Its always a good thing to read Sladhdot, and it had been a while since i looked at the site actually. Look what I found. Even better news is the message board thread has tons of satisfied customers. For those who do not yet know what I am blabbering about: This guy has hacked the firmware of the DVD-R(W) drive (SuperDrive) of the PowerBook. The PB SuperDrive burns a CD-R at 8x which is pretty slow to me. I have a Sony Spressa that burns at 12x and I am pretty used to that. My PC can burn at 48x and I can get reliable burns at anything under 40x. So 8x is really slow for me. The SuperDrive burns a DVD-R at 1x. The SuperDrive cannot burn a DVD-RW. This hack firmware allows 16x CD-R burns, 2x DVD-R burns and enables DVD-RW burns. Wow. There is even a "downgrade" available. I don't know if I am going to try this. The 16x CD-R burn speed is what I am really interested as I do not burn to DVD quite as much as I burn to CD-R. Why would Apple cripple these drives? The general consensus is the added heat and power consumption. Well don't burn while the laptop is on a blanket. I am really tempted, I might flash my burner for that 16x CD-R speed. With so many people reporting success I can only guess why Apple would cripple the hardware. It is not the first time Apple has crippled hardware, that is for sure. The 17" PowerBook has the same model drive but it reports a 16x CD-R speed and has a different firmware version as the 12" and 15" PowerBook. Hmmmm.... Read on for an insane amount of specs on a flashed SuperDrive.
