I have had an issue with Other in Storage.. I appear to have about 250 GB of Other, but only about 50 GB of any files, music photos etc.

 

I have had a good clear out of unwanted material and have still about 250 GB of Other, but my other areas have reduced in size.

 

I then read somewhere to do a Erase Free Space and that reduced things further.

 

However Other is still huge and I dont think I can upgrade to a new mac book pro with only 265 of Flash based on my current statistics....Other would take up the whole drive..!

 

Anyway, I noticed in Disk Utility that I have Macintosh HD listed at the top of the column on the left. THen just below it I have it given again! Exactly the same name..

 

Does anyone know if this is normal? 

 

Or have I done something wrong in the past that could be taking up huge amounts of space?

 

I had to reinstall the OS at one point and remember it created a new administrator profile for me, which I then had to delete via my original administrator profile and I only have my original admin profile now.

 

Any ideas?

    Does anyone know if this is normal?

     

    If FileVault is active, it's normal.

     

    Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:

    iPhoto Empty Trash

     

    Then reboot. That will temporarily free up some space.

     

    According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.

     

    If you're using Time Machine to back up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as "Backups." The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.

       

    To locate large files, you can use Spotlight. That method may not find large folders that contain a lot of small files.

     

    You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.

        

    Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.

     

    Proceed further only if the problem isn't solved by the above steps.

     

    ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.

     

    Back up all data now.

     

    If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.

       

    Install ODS in the Applications folder as usual. Quit it if it's running.

     

    Triple-click anywhere in the line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:

    sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper

    Launch the Terminal application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

     

    Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.

     

    The application window will open, eventually showing all files in all folders. It may take a few minutes for ODS to list all the files.

     

    I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.

     

    When you're done with ODS, quit it and also quit Terminal.
