I have enabled the mode to LBA, saved, exited, and rebooted and still show only 127GB in my computer. Yes, I said 127GB not the 137GB that I stated at first. I'm not sure if that makes any difference or not. I am already running sp3 on winxp pro. The ATAPI version is 5.1.2600.5512 and as far as the ms link which I read through I am a bit worried about changing code.
