I've had some weird problems since running that scrip and making two partitions for a total larger than 128 GB on a 160 GB WD HD. I had that drive in a Cube and it has frozen several times within the first 10 or 15 minutes coming out of sleep. I took the hard drive out and put it in a G4 digital audio and also had lockups and not been able to boot, so I'd like to remove lba-48. What is the way to do this? I reset the PRAM (command-option-p-r) on the tower and all seems to be well now. However, in the Cube I have a PowerLogix cpu upgrade, so if I have to reset the PRAM on that, it looks like I will need to re-run the firmware upgrade I had to do to install the PowerLogix cpu. Just wondering if there is another way to remove the lba-48? Thanks!
