RRFS Level 5 Level 5 (4,430 points)

I have a Mac Mini late 2012 purchased last week. I put a Mercury 240GB SSD into the top bay and upped the RAM to 16GB. I then formatted the SSD and used Recovery to install the OS on the SSD. The system performs as expected EXCEPT... when I use the Recovery Disk of either drive I get a message that both the original Drive and the SSD are damaged. If I select either drive it says if I choose Fix it will erase Both drives. Is this because Recovery sees 2 identical OSs on different drives? I had planned on erasing the 1TB 5400 drive that came with the MM but I'm hesitant until I resolve this issue. Any thoughts? Is the Mac Mini operating a "special" OS? I haven't seen this behavior before. Report says it's build OS X 10.8.2 (12C2034).  FWIW mylate 2010 MBA and early 2008 iMac have build OS X 10.8.2 (12C60). Is this a possible Bug as I haven't noticed this type of behavior before?

    Since I don't have two hard drives in one machine, I can't help much with your issue except to say that I have read that the new Minis do have a special build of OS (hence your rather strange build number), but I am not sure that this would have an impact. I'm not quite clear on this: do you have the OS installed on your original drive and your SSD? That may be your problem - it would certainly explain the confusion - my first reaction is that you should clone your OS from your regular hard drive to an external, make sure it boots. Then boot with it and wipe your internal as well as your SSD and clone the OS to one of them. However, there are more knowledgeable people here, so wait for input from some others.....

    I think you may be right that the two identical versions on the 2 drives has the Recovery Disk Utility confused. In thinking more about this it might be due to the new Fusion Driives that the Recovery Disk wants to remove duplicate versions of itself and act like one drive.

    I took the bold step and reformatted the original HD but the problem persists. I guess I'll call the support hotline tomorrow and see what they say. (Probably that a seperate SSD isn't supported)

    As far as I know, you can have a second OS on another partition, but not on the same drive - I'm clueless how that translates to a second  drive which is tied to the first one, but I am guessing they are considered as one drive by the OS. If you don't get other responses (your problem is a bit removed from the "run of the mill" stuff), you can call Apple since you're covered by warranty, but short of that, I'd suggest doing a clone, wiping both drives and installing on whichever one you want (I'd ask Apple about that as well - there may be a requirement as to which drive needs to have the OS.

    Does anything at > Mac mini (Late 2012) and iMac (Late 2012): About Fusion Drive help...?

     

    "The version of Disk Utility that comes with Fusion Drive is unique" and it sounds like you have disrupted the Single Volume setup. Problem is I don't know enough to really help, or if you can even get by running that way without restoring the Fusion Setup back to a single volume.... I do suspect that sense you can not install or use an older version of Disk Utility, your best bet is to first repair the Fusion setup and then reinstall OS X and your Data as per the Article.

    Thanks for that link - looks like my intuition may be correct,,,

    No problem -- I can't argue with that...

    OK. So here is where I am with the new Mac Mini. Thanks to den.thed's thread and Apple Telephone Support I now hav a 1.24 TB Fusion Logical drive. The SSD portion is linked at 6G negotiated speed and the HD is at the original 3G speed. It shows in disk utility as a single drive and as per Apple's constrictions can only have 2 partitions. It appears that the Recovery Utility will no longer allow discrete SSD and HDs in the same unit. As far as I have played with it since it got the OS installed it works the "way" Apple wants to let it work. As far as the Fusion setup is concerned there were several articles that described a Terminal command that would merge Volumes. This was however unnecessary. I ran Internet Recovery twice, the first time I had it "Fix" the drive it stalled halfway, I rebooted and tried fixing the other drive too. Disk Utility went ahead at this point and merged the drives into a "Logical Volume Group" that shows up as a single drive, I let DU do everything without interference and it now seems happy. The OS appears to have installed normally (whatever that is these days). I'll keep you posted if you're interested, this install (upgrade from 4GB-16GB RAM and 240GB SSD) saved about $200 over Apple's price and got me twice the SSD and a 6G link instead of 3G.

    I thought about your dilemma while ASC was down, that's good news your welcome!

     

    I spent some of the time replacing the 320GB 5400rpm HD in my 2010 Mac Mini with a 500GB Hitachi Travelstar 7200rpm HD. Then moved forward by Restoring Mountain Lion onto it from an External HD, instead of Snow Leopard from the original 5400rpm drive. I really prefer to keep my music and photos on the Internal HD and so I couldn't justify the cost of a larger SSD.

     

    So basically I flip flopped and now running Mountain Lion on a larger/slightly faster Internal HD and Snow Leopard from a FireWire External HD when needed.

    That is great to hear!

     

    @ denthed:

     

    What's the current level requirement for a user tip? I think RRFS should write one with step by step instructions - would come in handy once the new machines are in greater circulation....

    Thanks for the encouragement. Looks like I'm only 215 points away. I'll try to put together a cohesive explanation of what may occur if SSDs are introduced into the "new" Mt Lion environment. I suspect that when the new iMacs are released we will see this iteration of the OS become mainstream. It could affect ALOT of users like myself that like to tinker with their systems. I'm sort of disapointed that I don't have control of my system anymore. I've still got the 14 day window and may ask for the "Server" version of the Mac Mini so that I can partition my drives as I like. This "Fusion" thing leaves me wanting for simpler less controlling OS systems.

    ROFL....... sorry, I've been saying that since February of last year......

     

    Are you aware that the person in charge of iOS development is now (or will be shortly) also in charge of Mac OS. Saw a link somewhere which contained an announcement from Tim Cook to employees.

     

    This "Fusion" thing leaves me wanting for simpler less controlling OS systems.

     

    That is precisely why I bought one of the last iMacs that could boot in Snow Leopard as a refurb earlier this year. But, I have to say: Apple does listen - at least there are now ways to turn off/ignore Resume (I sent in a rather scathing bug report along with many others) and we got Save As back (another bug report for loss of functionality). So, not everything is bad.....
