I have a Netboot OS 10.9.3 (13D65) with Casper 9.31 installed. On my Mac mini 4,1, equipped with a 6G SSD from OWC, Casper Imaging cannot unmount the mini's internal disk for erasing. I cannot erase the disk/partition the disk when using Disk Utility on this Netboot set either. All other computers I have tested, ranging from mid-2007 iMacs up to a MacBookPro9,2, are able to use the same Netboot OS/Casper Imaging 9.31 and erase the disk before laying down a block copy of the OS. In most cases these other computers I have tested are running either OWC 3G or 6G SSD of similar size/vintage.
I can boot from an external drive and erase/partition as needed so I may be in the land of the "Casper on an External" for these 6 classroom console computers but am hoping there is an easier answer.
