I don't know much about how this works, but I don't have a recovery partition yet I can still boot with CMD-R and get into the recovery screens. It seems. This is with 10.8. I originally installed my Lion on a (OS X native software-) Mirror-RAID volume. I was told during the installation that OS X did not support a recovery partition on a RAID volume. This past weekend I used Carbon Copy Cloner to move this startup volume to a single SSD (using the complete device). It still had just the one partition. I then applied a 10.8 Mountain Lion upgrade to it. It did not say anything about re-partitioning and if I look at it in Disk Utility, it still shows just the one full size partition that it had before the 10.8 upgrade. I was able to do CMD-R to get into the recovery stuff (trying to repair some user directory ACLs in ~/Library), which I had never tried before. And it worked. So I wonder if it can install at least some of the Recovery stuff in the main partition? Again, I don't really know how this all works. Informationally, I also added a second SSD and moved my user account to that SSD (and changed the user account location in Settings). And I moved media files and mobile device backups to some standard hard disks and linked the Pictures / Music and ~Library/Application Support directories to this mirrored HD volume. This early 2008 Mac Pro once again screams in terms of normal every day use, where it had been bogging down with 5 year old Hitachi Ultrastar enterprise disks that were 66-75% full... Almost like getting a new machine :-) Chad -_______________________________________________ MacOSX-talk mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-talk
