    Again, you do not get it. I and many other people have been using such setup for many years now and it works great.

    Then why are you posting here if it works great?

    On the other hand, it makes a lot of ecological sense  and disk lifetime if you turn on 24 h a day 255 days a year a hard disk or only turn it on once a month or once a year.

    There are 365.24 days in a year. Spinning a disk up and down several times a year is more stressful on the mechanism than keeping it running constantly.

     

    And Time Machine is perfectly appropriate because the Time Machine disk is a different external disk where the external booting and internal disk are backedup. Again you got it all wrong.

    You are the one reporting problems with Time Machine.

     

    As said, I have no idea of command-line intefaces (including all text editors; I only know about Mac GUI) and just want a step-by-step method for newbies or dummies if you want to do what has been demonstrated that is possible (TinkerTool System).

    Then why do you continue to pursue that course of action when there are perfectly good GUI tools?   

     

    If you know how to do it, I will appreciate your feedback. Otherwise, please go elsewhere with your useless "wisdom" (sic). If you want to help, you must help (step-by-step procedures), not spit useless garbage. Because as has been demonstrated with your "useful" (sic) participation in this thread, all your levels and points are utterly useless. Or prove me wrong (step-by-step for dummies) and I will be most grateful.

    You are the only one to have used either "wisdom" or "useful" in this thread. On both occasions you spelled them correctly.

     

    I don't know why you persist in asking for step-by-step procedures for something you are already doing. You are never going to get Time Machine to work the way you want. Time Machine is operating as it was designed. When it detects something unusual, as in this case, it doesn't trust its incremental backup logic and performs a deep scan of the drive. DiskWarrior seems to have similar behaviour. This isn't the way the system was designed to work. Here is your step-by-step procedure:

     

    1. Setup system in unusual configuration.

    2. Live with the consequences.

    Would you like to share screen with me.  Im a visual person, I would like to see what happens.

     

    Do you actually use DiskWarrior?

    Actually, it is not my Mac but the Mac of other person. This is what DiskWarrior reports if the above procedure to prevent automounting at boot is implemented (no problem at all on the very same disk if the prevent automounting is not implemented):

     

    DiskWarrior has successfully built a new directory for the disk named "Macintosh HD." The new directory cannot replace the original directory due to a Mac OS services failure.

    Try rebuilding again. If the problem persists, please restart from the DiskWarrior CD and then try rebuilding again.

    All file and folder data was easily located.

     

    In the case ot Time Machine, it just does not make incremental backups, but full backups if a previously backedup disk that automounts is later on configured using the above procedure to prevent automounting at boot and then re-backuped again (Time Machine does a full backup then, instead of an incremental one). Actually, a Time Machine interference is also described at:

     

    Prevent a given partition from mounting at boot

    http://hints.macworld.com/article.php?story=20060930150059172

     

    where "andrewwynn" says:

     

    Super helpful with one major caveat; breaks time-machine restore capability. Backups still happen but you can not restore items that are within the drive mounted to a mount point!

     

    Yet, none of those problems (DiskWarrior and Time Machine) arise using "TinkerTool System - System Settings - System - Volumes - Exclude volumes from automatic mounting", which demonstrates that such feature is possible.

     

    Thanks.

    Pete, that has been sent to Apple Feedback and Apple Bug Reporter

    https://bugreport.apple.com/cgi-bin/WebObjects/RadarWeb.woa/wa/signIn

    many times in the past years.

     

    Please, do not include the full post before (maninly if it is long as in this case) just to include the feedback link to Apple as you have done. Let's keep the thread compact. Thanks.

    Compact????

    At the risk of raising your ire because I am not offeing a step by step solution, it seems you have already provided one in at least two posts. You have said, in the post I am replying to, that none of the problems [...] occur when using the Tinkertool method.

     

    Tinkertool is nothing more than a GUI interface to the same tools available to you in Terminal. It is not magic. But it is not allowed to be in the Mac App Store because it doesn't follow Apple's rules to NOT access the files that it can (that has already been explained to you). There are many effective and helpful utilities that are NOT allowed on the Mac App Store for exactly the same reason. That does not mean they are not safe, that does not mean they aren't helpful. As a matter of fact, they are probably safer than using Terminal where a simple failure to write a command exactly as you should can cause drastic and very difficult to correct problems; even a complete loss of all your data!

     

    But you seem somehow afraid to use Tinkertool while blthly typing in commands with absolutely no knowledge of what they might do or any assurance of the veracity of the person offering you the instructions. (I mean no offense to the people who have done that and I assume you meant no harm, but I also take the effort to determine what any Terminal commands will do before using them. ) That just seems like a recipe for disaster and not logical. Your fear of Tinkertool is irrational. Your use of commands entered in Terminal without understanding what they do is irrational. You abuse of the offerings of some is seriously missplaced and is likely discouraging anyone from offering any help. You post irrelavant opinions by telling others how to keep "your" thread compact. Sounds like you need to re-read the Rules on using these forums. And you can stop wasting your time thinking that this thread belongs to you!

     

    You say you know a solution (Tinkertool). So, why aren't you using it? Beats me! Have a great weekend. S'long.
