Anyone clone a GUID drive before? Have any issues? Was going to clone a working 10.5.2 GUID install. Figure I will just have to flag it the same as the original for EFI.

Ahh I just posted to disregard my questions, cloning it worked just as I thought. But i was pleasantly surprised by the improvement in disk speed on GUID vs. MBR. Also Has anyone played around with IOATAFamily.kext? I notice if I move the AppleNforceATA inside of it, and remove the other that overall performace increases, as does the decrease in spam while booting.

Ya, I'd be interested to know that too. Is there something that can be run from a CD, DVD, thumb drive, etc. that can create and/or restore a disk image (oops! here it comes: easily, simply, quickly.....)

eddie11c, on a 10.5.2 EFI + GUID System? If yes, I'd like to test your IOATAFamily.kext - want to attach it?

Ok ill attach it here if it lets me. Remove you old AppleNforceATA and just install this. I used to get lots of yellow text spamming during bootup, but with just this it only detects my nforce chipset once. As far as GUID vs. MBR my disk score went up about 10.5 points which seems like a fair amount.

Eddie Ide or Sata disk? I´ve noticed guid have better performance on ide disk than sata.

Eddie11c, thanks a lot, I'm going to test right now.

I have the same small issues like you described (yellow text) :D

This on a SATA disk, overall disk score went up from 87 to 97.5. Be sure your Device ID is in the AppleNforceATA inside the IOATAFamily before you replace it, or you will get the "waiting for root device".

eddie, now after I replaced the file and fixed the permissions - the system does not detect any Usb devices anymore. AppleUSBOHCI can't take control.

How to fix it? Currently booting in safe mode and posting with an iPod Touch. :)

hmm let me look into it. I dont even have an AppleUSBEHCI file.
