This probably won't work -- but why can't someone try to use a UMB install disk on a 13"UMBP to over ride the 1.5 Sata hd glitch? You know... nearly 100 hits on this thread and no comments? I am sorry to sound snobby but in the old days on MR there were actual engineers and people who knew about coding on these boards. What I am saying is that if the hardware is the same, and everyone who knows anything about Mac revisions on their install discs, they know that different speeds still get the same install discs of the same revision of computer -- then why wouldn't the install disks or something in the software on the Unibody MBooks work on the Unibody MBpros and get rid of the 1.5 Sata cap on the hard drives? OR why not swap out a UMB hd into a new UMBP and see what happens? IF it is a software issue, that is.
