I've read that when Mountain Lion installs, it now creates a recovery partion.

 

That wouldn't bother me at all, if my hard drive had just the single partition.  But my hard drive has 3 partitions.

 

What will the install process do to the existing partition structure?

    Nothing.

    I have three partitions on my hard drive - one Snow Leopard and the other two with recovery partitions, all created automatically when the OS was installed.

    Yes, they are real partitions. I had four partitions plus 10.7's recovery partition before installing 10.8 and didn't lose anything.

    Already answered, but I'll add: yes, they are partitions, albeit small ones and they are hidden (that's why they're greyed out). I created 3 partitions and the installer automatically carved an apprxo. 670 MB large partition out of each one for the recovery.

    Actually, your original post says you have 3 partitions, not 5.    And IMO, the graphical representation of your drive's structure is poor, it wouldn't be acceptable to me.  To each his own, though.

     

    Well, I created and have three usable partitions; the recovery partitions are not usable and are carved out of the existing ones. No need to pick that apart.

     

    As for the "poor graphical representation", I simply took a screenshot of the left hand column in Disk Utility. Sorry it didn't meet with your expectations.

     

    Good luck.

    It's become System Information in Mountain Lion, and is still located in the /Applications/Utilities/ folder.

    You cannot install a Mac OS version older than what your Mac came with. If you purchase a new Mac today you will not be able to install Snow Leopard.

    The key word here is "usable", which is isn't in your original post.  I wouldn't have questioned your response about that at all.  Recovery partitions should never be used, and we obviously know that.  But I've seen Windows users put data on that partition because they didn't know any better, and the mfgr. didn't bother to hide it from the casual user.

     

    Presuming things behind the scenes in Mountain Lion work the same as in Windows, you could unhide the partitions and use them, removing any read only flags.  And of course, someone wanting to install some version of Linux on a Mac, totally removing anything OS X related, those partitions will be gone.

    Now, that is a big disappointment if that's from Apple.    They should be ashamed of themselves.

     

    I've avoided upgrading because Apple, and now MS, are moving more and more to cloud related products, where I'm sure they will no longer sell you the apps for a fixed price, but make you pay a repetitive subscription fee if you want to use their products.  I make little use of the cloud, and never will.  It's a potential threat to my personal info and records if my data is stored there, and I make use of the cloud while working with the cloud based applications.  I never signed up for Mobile Me and iDisk either.

     

    My impression is, both Apple and MS are moving their systems towards the ignorant users, not the knowledgeable user.  Meaning you and I as knowledgeable users will be unable to make our computers "personal" to us.  We do it the way Apple and MS want, or we don't have a computer.  For MS, look at the UEFI interface that's required to be activated if a computer mfgr. wants Windows 8 certification.  I tell folks looking at new Windows 8 computers make sure of two things before they buy:

     

    1. Ensure the UEFI system can be turned off so you can install a different OS if you don't like Windows 8.
    2. Ensure you have rights to move back to Win7 as part of the purchase of the computer, in case you don't like Windows 8.

     

    I played with Mountain Lion for the first time today at a Superstore.  Could not find the System Profiler.  If that's gone, it will be a mark on the negative side of the ledger for Apple's OS for me.  If I don't like Mountain Lion, I'll have no qualms about reinstalling Snow Leopard.

     

    All in all, with the routes Apple and MS are apparently taking, they are making me an eventual Linux user.

    Why are you here? this post is of no use to the OP and boring as it is possible to be for the rest of us.

     

    I believe there are Linux forums, how come you are not there?
