[QUOTE="BondAMR, post: 1808424, member: 399056"] A strange thing happened when I used Target Disk Mode when I tried to copy the installer from a newly-purchased 2011 MBP to an empty partition on a 2011 MBA. The MBA partition is 30gb and the space that is needed is only 12gb to install but when trying to do this the TDM is thinking to copy all of the extra empty space on the 500gb MBP to the 30gb MBA and then gives me this “Not Enough Space” error prompt. If this is correct in what I’m saying, then why does it try to copy the whole drive space including the empty space and not just the 12gb installer on it? Secondly, when I used TDM in the other target direction the MBP could only recognize the separate partitions that I created in Disk Utility. It did not recognize the main “parent” drive called Yosemite, nor did it recognize an external USB drive called Mini, so my question is here why does this happen? Thirdly, I have noticed on 2 occasions that when you create a partition using a newer OSX like El Capitan or Sierras then that partition is not recognized when viewing it in an older OSX like I have been in Snow Leopard. I created 2 partitions on 2 separate MBP internals using El Cap and HS but then those partitions are grayed out in the index and unmountable when viewed using Snow Leopard. Wondering if anyone else has noticed this as well and why it happens? [ATTACH=FULL]28958[/ATTACH] [/QUOTE]
