Disk Utility and Info do not agree on capacity Used?

Hi.
Macbook pro 13' 2010.
120Gb SSD.
(320GB Harddrive in optical drive).
The SSD  is used to mainly run O/S and has only 5 first tier files, The size of each from Info tabs are:
11.14GB
6.77GB
4.07GB
6.3MB
8.0KB
Total: 22GB approx.
Disc Utility tells me that: 99.58 used . 19.6 available.
Info tells me that:  36.06 used . 83.12 available.
Why is there such a great difference between the amount of disk space used?
Thanks
Patrick.

  • Disk Utility and/or burner not working properly

    I always back up every new DVD I buy. The past month or more, every DVD I burn has been messed up. I always get a Verification failed error about 1/4 through the verification, and then the disc plays with so many stops and skips I have to restart the movie about 20 times, skipping past the bad parts, to finish it.
    The reason I don't think it's the software I use to actually copy/shrink/image is because I just tried burning an old backup image (from before this started happening), and I got the same Verification failed error and the DVD screwed up and crashed DVD Player.
    So how do I find out if it's Disk Utility or just my drive? I want to get this fixed. Thank you!

    There are any number of them available & they all work about the same way. If you have a preferred brand name you can pick from the likes of Fellowes, Memorex, Kensington, Scotch, Alsop, ad infinitum. Prices range from ~$7-$12, some higher. Best selection I've seen is:

  • Disk utility & TechTool Pro will not recognize volumes on hard drive

    My Powerbook G4 will not start up. This is what happens:
    1. Startup chime
    2. Hard drive starts to make a constant 'pause-click, pause-click' like a skipping vinyl record sound
    3. Then I only get as far as the flashing question mark on screen
    I have disconnected all peripherals. I have booted up from install CD and used *Disk Utility* and it does not recognize the hard drive, only the CDR drive. I have booted from the Apple Hardware Test CD. All hardware passes. I have booted off the *TechTool Pro CD* and tried to run the entire suite of diagnositc tests. All hardware passes, all drives pass, but when I get to Volumes and Files, none are recognized. I have tried to get to the *Startup Manager*, but I can't get to that point either, only as far as the flashing question mark. I would like to be able to salvage data from the harddrive, so haven't tried to reinstall software and OS.
    It seems to me that the hard drive is probably dead and I probably need to replace it, but is there any hope to recover data from the old hard drive
    Any suggestions on what else I might try or on confirming my tentative diagnosis, would be greatly appreciated. Thanks

    Thanks for the quick reply Tom,
    I mostly save my work related documents on external flash drives or zip drive media, so my most important data for the most part is backed up. However, I had gotten a bit unattentive with personal interest stuff, like photos, music etc. I'll probably think of something important months from now and realize it was only on that drive, but for now I am most concerned about my downloaded emails and email addressbook. I never thought to back those up. Makes me want to stop running Thunderbird and keep all my emails online. Anyway I have some recent business inquiry emails from new contacts that are stuck on that drive. Can't recall the exact name of the organization this person was with. Aghh.
    Think there is any use trying one of those data recovery programs to see if I could extract some information from the disk?
    I am realizing that I will probably need a new hard drive to get the computer running . A friend's dad who is a computer teacher (though mostly PC but has kids with Macs so he's been working with Macs a bit and learning) mentioned the possibility of putting in a new hard drive as the start up drive then installing the old one as a secondary hard drive so I can try to access my data that way. Think that sounds like a feasible option to try? Perhaps I could run the recovery within that configuration. Worth a try? Pointless?
    I appreciate any words of wisdom or commiseration.
    Thanks,
    Applangel

  • I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data.

    I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data and it does not show on the desktop when connected.

    Ok if disk utility was able to verify the drive I doubt there is any problem.. are you trying to open a TM backup??
    You need to mount the sparsebundle then check the actual info inside the bundle.
    Don't use disk warrior.. if the disk has verified then unless you deliberately deleted files there is nothing that is going to do.
    Pondini has a lot of stuff about getting access to the sparsebundle.
    http://pondini.org/TM/17.html
    But if you have copied info to the TC that is now gone.. and the disk is ok.. I am not sure.. the TC will not have deleted the files itself.

  • Have a mac book pro that crashed. ran disk utility to repair. comp booted and ran for short time. then crashed. ran repair again. disk utility said it could not repair files and i needed to format hard drive and start again. now nothing works

    Erase and Install
    1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
    4. Quit DU after formatting completes and return to the installer. Install Snow Leopard.
    5. After restart into Snow Leopard download and install Mac OS X 10.6.8 Update Combo v1.1.

  • I have all of my iTunes music on an external hard drive (Glyph 3TB), all of a sudden iTunes will not play any of my music. i ran disk utility and i'm good. What else can i do??

    Greetings,
    I have a macbook pro purchased in 2009. I run the current Yosemite OS X on it, and have over 12, 000 iTunes music tunes stored on an external hard drive (Glyph 3TB). Recently iTunes does not load up on my computer. I've ran disk utility and repair, etc and it says everything is fine, however i can't seem to get iTunes to come up and play music. My questions:
    what can i do to fix this?? Is my macbook pro too old that i need to seriously consider purchasing a new one?? If i purchase a new macbook pro, can i hook up the Glyph 3TB to the new one and have it play my music without problems/?
    Thanks,

    LaCie doesnt make ANYTHING.  It contains a Seagate 3.5" 5400RPM HD.
    Check the HD on another computer, if nothing, your SATA bridge is fried, or the HD (very unlikely since its a Seagate inside)
    Youd have to crack open the HD, remove the SATA bridge cart thats plugged into the HD and put the HD into an enclosure or a HD dock to get the data
    those external HD use a 50 cent SATA bridge famous for failing.  The curse of all the good HD externals is the junk 3rd party SATA bridges attached to them that crash and burn.

  • Disk Utility and Disk Repair function

    I ran the "Verify" function on the hard drive and came up with an Error, but can't figure out what to do next. The option of "Disk Repair" is grey. I found an older discussion about the specific error message - "Incorrect size for file YellowPushBtn_Pressed.tiff (It should be 0 instead of 5602)" This older discussion lead to the QuickTime application, but I was unable to local the file they talked about.
    Any ideas on how I should proceed from here?
    Thanks

    Disk Utility won't repair the drive if that drive is the one from which the computer is currently booted. The usual thing to do is boot from the installer disc. I don't know about the shift key; I thought it was holding down the C key to boot from an optical disc.
    What holding down the shift key does is boot you to safe mode which reduces the number of things running to a minimum. I have found that while you can verify a boot drive you can get errors and an analysis from safe mode reduces this likelihood.
    *General Instructions*
    Boot from the installer disk, select language if applicable, choose utilities, run Disk Utility and verify (and repair if necessary) the drive. You can verify a drive from DU on your main drive while booted but I have found this can result in incorrect reporting of errors. To repair your drive you have to run it from a drive other than the boot drive anyway.
    Next, boot from your drive in [Safe Mode|http://docs.info.apple.com/article.html?artnum=107393] and repair permissions. You can repair permissions while booted from the installer disc but this uses the permissions configuration on the installer disc which may be out of date if you have run any updates on your computer. Booting your computer to Safe Mode restricts the number of things running on your computer while permissions are being run and does a bit of spring cleaning at the same time.

    From BDaqua (couldn't have said it better):
    "Try Disk Utility
    1. Insert the Mac OS X Install disc that came with your computer (Edit: Do not use this disc if it is not the same general version as what you have currently on your computer, e.g. use a Tiger disc for a Tiger drive, not a Panther disc), then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk.
    Then Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes."

  • Disk Utility (in Recovery Mode) not seeing internal MBP SSD

    MacBook Pro 11,3, Retina, 15-inch, Late 2013
    Having an odd problem which occurred under both Mavericks (latest build) and Yosemite (10.10.1).
    Under Mavericks, I could not boot at all into the Recovery Drive; I would get to the choose language screen and get the beachball of death. I do not recall exactly when this started happening, but it was long after the last update.
    To repair my drive, I would boot into Target Disk Mode, hook the MBP to my wife's iMac, and run DiskWarrior to replace the directory on the main drive, and then run Disk Utility for Permissions Repair and Disk Repair, which would usually find no errors. I would then boot back into my account with no problem, but if I tried to boot into the Recovery Drive, it was the same issue.
    If I booted from a Clone (made via Carbon Copy Cloner) of the Recovery Drive, I could get into Disk Utility, but the drive would not be recognized.
    Flash forward, I did a nuke & pave of the MBP, a clean install of 10.10.1, and then started rebuilding my Mac's identity, per se (been meaning to do this for years; I think I haven't done a full/fresh install since about 10.2).
    So I'm rolling along and decide to boot into Recovery Drive -- I'm able to get through almost everything without issue. I am hopeful. I launch Disk Utility, and then I see my drive -- "1 TB Apple SSD..." -- but below it, instead of the drive name, I see "disk0s2". I can't run repairs on anything.
    I'm not keen on doing yet another nuke and pave. The system seems to be fine, everything is running without issue, and (bootable) backups are going along fine.
    Any thoughts on what might be the issue? I've read something online regarding "Core Storage" issues with how the drive was formatted, but according to my info, I'm on a standard GUID Partition Table.

  • Help needed. I have a 3TB external hard drive partitioned into 1TB's. I used one partition as backup for the main computer hard drive. But now it is greyed out as shown in the disk utility and its name changed, i dont know how that happened, i tried verif

    Help needed. I have a 3TB external hard drive partitioned into 1TB's. I used one partition as backup for the main computer hard drive. But now it is greyed out as shown in the disk utility and its name changed, i dont know how that happened, i tried verifying and repairing it but had no luck. I also tried mounting and unmounting it but still no solution. Anyone to help please?

    Looks bad. I would strongly advise backing up the stuff on the other two partitions as soon as possible in case the rest of the drive goes wrong.
    Beyond that, Disk Utility has limited abilities to repair disks, DiskWarrior uses a different approach and might, emphasis might be more successful. It has certainly done the job for me in the past when Disk Utility could not.

  • Mac OS 10.5.6 downloaded Firefox 3.6.13 Came as .dmg When I try to launch it says "Not Recognized". Right click for "Open With" refers me to Disk Utility when same results "Not Recognized"

    About my Mac > G5 Desktop OS 10.5.6

    The download comes as a compressed file in .dmg format. When I attempt to launch the .dmg file to decompress I get a error message that says: The following disk images failed to mount: Image > Firefox 3.6.13 Reason > Not Recognized. When I right click to see what opening app it is directed to it says: Open with "DiskImageMounter (default). Disk Utility is offered as another opening resource when I direct the file to Disk Utility and go to Menu Bar select "File" then select "Open Disk Image" (or Cmd + "O") I get the same result. Have tried downloading the file twice more and get the same results

    Vk2mh it sounds like the download was not complete or corrupted.  Where are you downloading the update from?  Have you tried downloading again?

  • Time Machine, Disk Utility, and clearing out corrupted snapshots

    Hi, all. I've been having some troubling issues with Time Machine and could use your collective insight.
    I have a 500GiB external USB2 disk that I've been using for Time Machine since December (the oldest snapshot in Backups.backupdb is named 2007-12-13-222250). Everything worked fine until sometime in late January, when Time Machine decided to ax 2/3 of my Applications directory. Time Machine's logging is terse, so I wasn't able to determine what caused the corruption. The fact that this error wasn't caught and flagged by Time Machine bothers me.
    Especially because I discovered this in the process of needing to recover from a crash on my laptop's hard drive -- I had to roll back to a previous, complete snapshot to get all my applications back.
    After that I had to engage in some jiggery-pokery to get Time Machine to re-snapshot everything, but things proceeded normally until I received my new copy of DiskWarrior 4.1 last night (although DiskWarrior is an innocent bystander here). I tried to use DiskWarrior to rebuild the directory on the Time Machine disk, but it failed before trying to write anything.
    (For those who care: after some back and forth with Alsoft tech support, we determined this was likely because my Time Machine volume has 6.2GB of catalog data, and DiskWarrior works by rebuilding the directory in memory, so it has to be able to fit the whole catalog into virtual memory.)
    I was a little paranoid that something might be wrong with the disk after that, so I fired up Disk Utility and told it to repair the disk. It churned for about 6 hours and repaired an extraordinarily large number of hardlink reference count errors, but completed by claiming that the disk had been repaired.
    When I next told Time Machine to run, instead of copying over a couple GB of data like it usually does, it started copying 38GB! ***? I took a look at the previous Time Machine snapshots, and discovered that Disk Utility had totally corrupted every snapshot I'd made since last month's fandango. Most of the root-level directories in the snapshots now look like this:

    Since I also use SuperDuper! to regularly clone this disk, it's not as big a nightmare as it could be, but this means that I'm going to have to clear out every snapshot for the last month by hand, both because I obviously can't trust them anymore, and because I keep getting messages like this in the logs:

    I'd like to keep the old snapshots if I can. What's likely to happen if I just go and clear out the b0rked backup sessions by hand?
    (Hmm... it appears yes, because I just deleted them all and the disk didn't recover the freed space.)
    Here's the important question: has anyone else had issues using Disk Utility on a Time Machine volume, and does anyone at Apple have any plans to add integrity checking to Time Machine? As it stands, I don't really feel like I can trust it in its present form, as convenient as it is...

    I have trouble with disk utility on my new (1 TB Lacie) as well as on my old (500 GB WD) drive. After doing a backup, du tells me a never ending list of errors like
    HasFolderCount flag needs to be set (id = 599567)
    (it should be 0x10 instead of 0)
    Everything was O.K. before doing the backup; so is the disk to be backupped, according to du.
    Up to now, no other problem occurred, but I´d like to clear this issue before my trust in time machine is restored.

  • I need help on my MacBook Pro. Recently I've deleted another partition of my disk from the disk utility and I found out that my disk capacity wasn't get into the normal one which is 750GB. Meanwhile I installed window 7 into the partition disk.

    I need help on restoring my disk capacity back to normal. I installed window 7 into the partition disk through bootcamp and I deleted it from disk utility. After I erase the partition disk,I get my capacity to 499GB but not 750GB. Do I need to reinstall my MacBook or something to do with the restoring?

    You shouldn't do it. You have to erase the Windows volume with Boot Camp Assistant, so it will restore the space onto the OS X volume and that volume will have 750 GB.
    As you did it with Disk Utility, you have to resize your OS X partition manually:
    1. Open Disk Utility, select your hard disk at the top of the sidebar, and go to Partition tab.
    2. You will see a bar with Macintosh HD. You have to click it at the bottom right corner and drag it to the end of the bar, so Macintosh HD will use all the space of the hard drive, and press Apply.
    3. Close Disk Utility and your OS X partition will have 750 GB
