have downloaded my copy of Mountain Lion DP4 (yes i am part of the apple seed program). trying to burn the InstallESD.dmg to a USB stick to do a clean install. i'm using the same instructions i used for Lion - Disk Utility > create 1 partition with GUID > then restore the DMG to the USB stick. i keep getting the following error. any ideas why? (it's a 16GB USB stick). it fails at around 90%-ish of the way thru restoring.
