Disk space in Get Info

The Get Info page tells me I have 1.74 Gb of space left on my 75 Gb drive. In trying to decide what to trash, I looked at the sizes of my individual files/folders. These add up to only 40 Gb. Now, I thought that Mac OS X is supposed to defrag files on the fly, so where has all my supposed free space gone?

Fragmentation has nothing to do with your problem. Your problem is you have too much data stored on your hard drive. That's where your free space has gone. You can use a untility like GrandPerspective to array your files and folders based on size to try and see what you have that's taking up space. But before you start deleting things just take a warning: stay out of the /System/ and /Library/ folders. Deleting from there will only cause OS X to stop working. Here are some maintenance tips:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard.
OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. Carbon Copy Cloner (Donationware)
6. SuperDuper! (Commercial)
7. Intego Personal Backup (Commercial)
8. Data Backup (Commercial)
9. SilverKeeper 2.0 (Freeware)
10. MimMac (Commercial)
11. CloneTool Hatchery (Shareware)
12. Clone X (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at www.versiontracker.com and www.macupdate.com.
Ultimately think about getting a larger hard drive.

  • Available Space in 'Get Info' for HDD does not match with the files

    I have a 75G HDD on this Macbook. The 'Get Info' for the HDD says I only have 1G of space available. However, when I go item by item in the HDD, and total the sizes myself, it only totals to 30G of space being used.
    Anyone heard of this problem before? Are there files hiding somewhere? How can I get more useful space on this HDD?

    Hi and welcome to Discussions,
    use something like Disk Inventory; JDisk Report or OmniDisk Sweeper to really find out what is consuming your disk space.
    http://www.macupdate.com/info.php/id/20598/jdiskreport

    http://www.macupdate.com/info.php/id/7402/omnidisksweeper
    OSX hides quite a lot of system files from the user for the sake of safety.
    What to delete and what not is your choice.

  • My MBP said my disk space was getting full. I made space and 2 hours later it notified me it was almost full again. I deleted more files and now I can literally see space disappear from my Finder. How is this happening and where is it going?!!!

    Please HELP ME!
    I'm not sure WTH is going on, and it's frustrating the crap out of me.
    I don't have any external drives connected, and I've never had this problem before.
    ***NOTE: suddenly now it's showing that I have 30gb+ free. WTH just happened?!***

    Time Machine is having fun with you.....
    Seriously, if you check the Time Machine configuration in System Preferences, you will probably find that it is taking snapshots of the disk drive. Since those take up space, and old ones get deleted, that would explain what's going on.

  • How to find out disk space?

    I know two ways to get some information about HD space. One is to Control-click on Mac HD and select Get Info. A dialog is displayed with detail information which contain Capacity, Available and Used numbers in GB.
    Another way is to use Terminal with command df -lhg. This command displays similar information. However, by using command, the numbers I get are less than those in Get Info. They are not the same. Not sure if my command is correct or not. If not, what is the correct command to get disk space information?

    Great! I will not need to worry about to reset the BLOCKSIZE back to the default value.
    One thing interesting. Before I installed the Snow Leopard, I checked my disk space with Get Info. My HD available space was about 466GB. After the OS update, Get Info shows the capacity as 499GB. I thought that I got 30GB more space back. Actually, today I realize that the Get Info value of the pre-OS as based on the binary decimal, and the Get Info value of the Snow Leopard is 10-based decimal! This explains my question about my question of the difference of the Get Info value and the value of command "df -lhg"! "df -lHg" shows the same result, which is 10-based decimal value! I actually did no get more than 30GB disk space.

  • Disk Space Usage on my Mac Mini

    Where has all my disk space gone?
    Info on my Mac Mini drive is as follow;
    Capacity: 74.21 GB
    Available: 9.68 GB
    Used: 64.53 GB
    Doing the info on all folders visible in Finder;
    Applications: 5.29 GB
    Developer: 160kB
    Library: 10.75 GB
    System: 2.53 GB
    Users: 13.8 GB
    I don't even have to try and add these up as they are nowhere near the total of 64 GB used, so what directories/files are not visible? Or what is using more than 30 GB of space that I cannot see?
    I trying to free space up and or move things of this drive because is is dog slow right now and it.
    Any insight would be appreiciated.
    Warren

    OK, So I dl'd that and ran it and it only showed an additional swap file directory called "Private" that had about 3 gigs, still about 27 gig's missing.....
    In this program the bottom bar shows 74.2 capacity, 61.5 used, 12.6 available
    Big directories (anything over 1gig)
    13.7 users
    10.7 Lib
    5.28 Apps
    2.53 System
    2.93 Private
    About 35 gigs
    then a bunch under 1 gig that total less than 1 gig,
    so say around 25.5 unaccounted for ?????????????
    nice program but still wondering where my hard drive space has gone.....

  • Tempro v2 - changing threshold for disk space alert

    Hello,
    I have downloaded and installed Tempro v2 on a Satellite A200. It is running fine.
    However, tempro has a problem that was present on the version 1.x .
    The low disk space alert is set to trigger, way, way too early at 25% disk space left on any partition. On a modern disk this is around 15GB. This is way , way too early to be told of a problem. I have swiched off this alert - which I don't want to do. There seems to be no way (that I can find) to set this alert to trigger at a more sensible value - say 10% disk space left or a given amount of disk space left - say 2GB.
    Is there a fix for this or have I missed how to set this value as I don't want to run without knowing I am running low on disk space? Getting this alert at 25% is irritating.
    Thanks
    Clive

    Hi
    I dont think that you could change this value or settings
    Tempro sends the notifications about the status of the whole HDD and therefore you have received this message.
    Ive got this tool on my notebook too but didnt find any settings which would help to disable the notification about single partitions on the HDD

  • Disk space vanishing, other strange behavior

    In the last two days TechTool has been announcing that my free disk space is getting low. Started at 15%, but it keeps dropping down to 1%. I've deleted about 100GB of data in the last two days, but it isn't helping.
    Checked my log files which aren't ridculously big. None of my processes are using a fraction of the 160GB+ it shows as being allocated to VM. Some strange log entries in console related to MacHelper, but I don't think I ever installed it. Ran an uninstaller just in case.
    Prior to this happening some other odd things have been happening for a week or so:
    External drives aren't dismounting correctly. Click eject and the name remains grayed out and if I unplug the drive I get chided for removing a drive.
    System hangs and requires forced restart. Hangs during restart on the desktop image.
    Had some trouble with an external e-sata drive dismounting all the time using the card slot adaptor for e-Sata. Card would get extremely hot. Used FW800 but had strange behavior with 5 additional drives reminiscent of SCSI. Once I changed the cables around it stopped doing this.

    You may not have gotten all of MacKeeper. From an earlier post of mine:
    I'd search for it using EasyFind. Enter "MacKeeper" and "Zeobit." Set EF to scan all files and folders, invisible, case insensitive, package contents. Search using boolean and phrase. It will probably do a more thorough job than Spotlight. If you can't "Destroy" from EF, use Reveal in Finder to trash and authenticate from there.
    It is also known to install a Windows emulator called "wine;" search for that.
    Also, look in the Keychain for anything MacKeeper or zeobit related, and for its cookies in your browser. When finished, empty the Trash and restart.

    Somehow, as BDAqua suggested, I'm still suspecting it's the logs filling up with a constantly repeating message. Are there any other Users? Can you log in to those and see what's going on with those logs?
    Permissons repair has nothing to do with this.

  • Missing disk space - 'get info' differs from 'du'

    Hi there
    I have three harddrives in the server - one 80 GB drive for the system (called Server HD) and two 1TB drives for the home directories and network shares.
    The problem is that, according to 'get info', the 80GB drive is almost full (only 6 G left) and I don't know where all the space is used.
    When I the applications 'disk inventory' or 'whatsize'(in administrator mode) or the terminal with 'sudo du -shx /Volumes/Server\ HD' they all report a disk usage of about 23GB, which is more likely as the system is just a few weeks old and the home directories are not located in this volume.
    But if I use 'df' to see the free space this reports the same as 'get info' - only about 6GB left.
    According to the system profiler the smart status is verified, so the disk should be ok (I think).
    Unfortunately I am pretty new to Macs so I don't have the slightest idea what to do now to check and hopefully reclaim the missing disk space.
    Thanks for any tips
    Claudia

    Look in /Volumes directory there should only be an alias or mount point for any volumes you have mounted. If a volume didn't mount properly, it is possible to find "name" and "name_1" entries, and for actual files to now reside there.
    Another utility I like is from OmniGroup
    http://www.omnigroup.com/omnidisksweerer which should easily show where space is used.

    Any ideas on what to do next?
    I'm running and iMac 20-inch  early 2009
    Processor  2.66 GHz Intel Core 2 Duo
    Memory  8 GB 1067 MHz DDR3
    Graphics  NVIDIA GeForce 9400 256 MB
    Software  OS X 10.8.4 (12E55)

    Step 1
    Quit Calendar. Triple-click the line below to select it:
    ~/Library/Calendars/Calendar Cache
    Right-click or control-click the highlighted line and select
    Services ▹ Reveal
    from the contextual menu. A Finder window should open with a file named "Calendar Cache" selected.
    Move the selected file to the Trash. There may be one or two other files in the same folder with names that begin in "Calendar Cache". If so, delete those files too.
    Step 2
    Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash as well:
    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.
    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.
    Install ODS in the Applications folder as usual. Quit it if it's running.
    Triple-click the line of text below to select it, then copy the selected text to the Clipboard (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 some 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.

    buy an external HD   1TB for $60
    NO notebook is a mass storage device, so dont try to turn it into one, it doesnt work that way.
    Unless youre using it every couple weeks, its static data and should be on an external HD
    In the case of a Macbook Air or Macbook Pro Retina with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace.  You should never be put in the position of considering “deleting things” on your macbook SSD in order to ‘make space’.
    Professionals who create and import very large amounts of data have almost no change in the available space on their computers internal HD because they are constantly archiving data to arrays of external or networked HD.
    Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your macbook has a HD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your computer to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.

    I have plenty of disk space so that isn't the problem.
    It could be. The download assistant has issues with large partitions over 1TB. So in fact you may have to downsize. Anyway, you're not providing enough info to be any more specific.

  • How does Get-Info manage ext disk access & permission

    I was having a terrible time today trying to back up my HD to an external drive. I was using SuperDuper. The SD dialog box allowed me to choose 2 of my ext drives as targets. But the drive I preferred was 'greyed out'. I couldn't select.
    So, I thought that perhaps I didn't have read-write permission for it. I pulled up a Get Info dialog box, and this is how it is configured (see below).
    My user name doesn't even appear in the Sharing and Permissions box.  Nor do I see the little check box which asks IGNORE OWNERSHIP.
    I clicked on the little padlock icon and entered my password. But I still couldn't change the configuration. I just wanted to back up to that one disk named 2tb Boot-backup. Nothing more. The drive is a boot drive, incidentally. But I was running the OS on my main HD (iMac).
    Frustrated at this (the Missing Manual didn't help), I gave up and reinstalled Mavericks on that ext drive. It fixed the problem, at the cost of 2 1/2 hours.
    And I'm not any wiser about how Mavericks controls access. Screen shots below tell the story. My User Name does not appear in the Sharing list. Please teach me.  Where is David Pogue when you really need him?

    For a very long time before making my purchase choice, I neurosed about the processing power demands if Aperture. Few folks at MacRumors knew what specs would suffice. I must have exchanged 15 posts over there and learned little.
    At the time I had a 2007 iMac with 6Gb or RAM. I borrowed Aperture from a friend and played with it. Knowing that would I made a computer purchase from the Apple Store, free softeware would come with it. I prefer to be play straight. Not because of fears of the 'software pirate police.' I want the support and documentation.
    By having the actual program loaded in my box, I began paying watching the Aperture Tutorials on the Apple Support website. In the case of Aperture, there is a whole lot to learn. A huge amount. Maybe because it was my first PP and DSLR experience. It took a lot of time to get comfortable.
    Eventually, I discovered more AP tutorials on YouTube. And then, I found the so-called Silver Bullet. The Aperture forumlll. The answer I wanted was neither simple nor straightforward. But I was able to decide on the right Apple machine, with an adequate CPU, GPU and RAM.
    Aperture processes some function in the CPU. It processes others in the GPU. And RAM undergoes heavy pressure only at certain times.  While 'Importing' RAW files from an SD card, the CPU works hard. It is best to have clock speeds of at least 3.2Ghz. Along with the image, Aperture will import the embedded camera preview in Jpeg format. Things go faster if you select to import the file and preview. Regardless, camera previews are small and low resolution. Aperture then favors generating its own hi-res JPEG for use will browsing your library of photos.
    Editing an image, which is called an 'Adjustment' in the program doesn't take nearly as much processing power as one would expect. Aperture is a non-destructive program. The original RAW file is never touched. All the changes are merely tacked on and are reflected on the screen or when saved as 'Versions' only. The version is tiny compared to the master file.  A good metaphor would be baking. You might start out with a Lemon Cake in the oven. But then you put Chocolate frosting on top. The result looks and tastes different. But it is always a Lemon Cake.
    The GPU then takes over. Late generation GPU with at least 1000Mb of video ram, 32-bit color depth would be minimum. The NIVIDEA Geoforce GT 755 satisfies those demands. Though if I ever start playing with Video instead of Sill, I might wish for 64-bit color space.
    I probably have some of the details mixed up. But the fundamentals given are what I heard. At least one of the responders on the Aperture forum was on Apple team that wrote the software. That's all I know, and I'm not trying to get anyone to 'change religions'. SSD ain't going to make my image editing improve. Incidentally, on my iMac, Aperture loads in about 4 seconds.

  • HD Get Info Showing Different Size After Using Disk Utility

    I recently removed my second partition I used as a back up to free up some more space. I booted into the Leopard install CD and ran disk utility to delete the 2nd partition and resized my "home" partition to ~148GB and had no issues. I booted into Leopard and used "Get Info" on my "home" drive and noted it showing my HD size was only ~74GB. I used find to search for files on "This Mac" where size was greater than 500 MB and found nothing unusual. Does anyone have an idea what this issue could be?
    Thanks in advance
    Matt

    Hi Tom,
    Of course, that makes perfect sense! When I made my last disk image backup, my PowerBook had a serious, undiagnosed problem and I had booted from the startup disk to have a current backup of everything before I sent it off for repair.
    Thanks for your help.
