Wondering what you use to format those mSATA drives? Got one all hooked up and Drive Setup on the OS9 install CD from my store bought 10.1.2 set says it's unsupported.I made my own 128GB from eBay parts... these work in all my PPC so far (2.5 to 3.5 adapters for the desktops, $4), as well as in the gen 1 Apple TV.
44pin 2.5 IDE to mSATA adapter ($13@) with some refurbished drives Lot of 5 mSATA drives ($40 for 5).
Need any 2003 MDD bootable CD with formatting tools on it.
