I think I just lost my entire Aperture Library. Please help!


My iMac froze as I draged photos into my Aperture Library. I did force quit. Then Aperture would not read my Library file. The error box says "There was an error opening the database for the library "/user/Peter/Pictures/Aperture Library.aplibrary".


The rescue process of opening Aperture while holding down the Option and Command key will also not open the Library.


I realize now that my library was 146gb, which may be too big for Aperture to handle.


What to do?


I'd really apreciate help from anyone who know a solution for restoring my library file.



iMac, Mac OS X (10.7.5)

    First thing the size of your library is not the problem.


    So what happens when you start Aperture holding down the command and option keys?  Please be specific with any error messages or alerts you get.

    Glad you got i sorted out, Leaving enough frees space on a disk is very important, especially if the disk is the system drive. Running short of space on the system drive can cause all sorts of problems.


    You might want to go back and have a look at the system drive and see just how much free space there is. 10% of the system drive free is a good rule of thumb. If you have any questions post back.

    Ah that wonderful topic, Should I defrag my OS X disk?


    This comes up often not just here and you will find that there as as many opinions on this as there are posters in on the Internet, basically an infinite number


    While in the past with older OS and disk technology defraging was sometimes beneficial I am of the opinion that with modern OS's and technology this is no longer required and in some cases can actually lead to a decrease in performance.


    There are a few cases where defraging might be beneficial, I'm thinking of video editing where you are streaming huge amounts of data but then those files should not be on your system disk anyway.


    So for me this is a none issue I don't defrag and I don't believe it is worth the time and resources so I can't give you any specific recommendations for software to do this. You could copy everything off your root drive, erase and format it, install the OS and then copy everything back. That will put things 'in order'. Remember you have to copy not clone as a clone will just put things back where they were to begin with.


    If you do do this please post back both the results of Diskwarrior after the defrag and if you think it was worth the time and effort.


    Remember system performance depends on a number of factors, root drive free space, the health of the drive, the amount of memory in your system matching up with the way you use the system, etc. If defraging buys you anything I would put it far down that list.

    Pebiski  defrag is a big conversation, and everyone has 2 cents to throw in.  Here is my 1 cent of knowlege to think about.  Like Frank said copy your lib to a external HD (recentley formated or defragged) but before coping it back make a separate partitan on your root drive to hold your lib plus 3x the space.  You can use disk Utilites to create the volume.   I use idefrag but I believe that Disk Warrior defrags as well.  Once the volume is made copy the lib back.  the process of coping and deleting the vol  and coping back the lib  is a safe way of defraging but I have idefraged my Lib Volume in the past, I will denie that in a court of law if you have problems:)   Cheers
