I was wondering if it is possible to move a Drobo back and forth between several Macs? Or are there preferences or something in Drobo Dashboard that keeps important info, and then make this not an option? Also, am I right to assume that when you put your first couple drives in a Drobo, that they have to be blank/empty and that they have to be formatted by the Drobo software? Or could you put 2 x 1/2full 1TB drives and one blank 1 TB drive in? Thanks in advance. Macsales.com (OWC) has some good rebates on Drobo today. I was thinking of getting one.
