Well, I tried to update the firmware 1.23>1.24

Pulled the drive from the macbook pro, attached to a W7X64 machine. No joy.

The drive and it's partition scheme showed in the W7 drive management dialog, but the firmware updater could not find the drive. Tried attachment both via sata and usb.

Looks like I'll have to build a spare drive up with W7x32.
