Lost free space after an "Erase Free Space" procedure

I just ran the "Erase Free Space" application from the Dick Utility. The erase failed and now I have ZERO free space available. I am now showing that all 111g or used oposed to roughly 50% prior to the Erase Free Space. I have found a few articles trying to explain what to do but, I have been unable to locate the empty temp files that we created during the Erase Free Space, so I have been told. Can anyone help me resolve this solution and restore my free space?
Thank you,
Shannon

WhatSize should be able to find the temporary files

You could try the Erase Free Space from Disk Utility on the install DVD. It might delete the files when it finishes.

  • Time Capsule full after a "Erase Free Space" using Disk Utility

    Hello,
    I am facing some issues related to my Time Capsule.
    Reviewing my past, I had a lot of backups on this, using Time Machine and it always worked pretty well. But after deleting some backups manually to reclaim disk space, this was not exactly freeing it.
    Searching in the forum here, I saw that I could mount the backup sparsebundle image and map it into the Disk Utility. This always worked greatly too both for disk checking and reclaiming the space back.
    The problem starts on the last Friday when I performed the operation again, but it started using the whole free space that I had and did not give it back.
    Studying the case I found that it creates a temporary folder to store the file it creates to write the byte 0 on the disk. This file actually resides in the sparsebundle image and therefore I can see the file with 200GB, for example, in the Finder, this is a split in bands (8MB) just like the backup is. After the disk gets full, the Disk Utility should delete the file properly and give me back the space safely.
    Right now my Time Capsule has 0 byte free and I can't do anything on it beyond redo the the Erase Free Space operation. When I do it, it starts writing the temporary file again and the problem repeats itself.
    I know that if I backup the data and really erase the disk, I'll get it back, but this is not an option for me because I want a smart solution for this.
    The only thing that changed between when it worked and now is the 10.5.6 update that I made and I'd like that it's not the root of the issue.
    Is there any suggestion or general stuff I could do to fix it?
    Did anybody already face the same issue?
    If anyone needs more details to help me out of this, just let me know.
    Thanks and regards,
    Eduardo

    Just another thing to add, I'd like a good solution for this as the redo operation from Disk Utility takes around 2 days and then it just "dies".

  • After using "erase free space," hard drive has almost no available capacity

    I decided to clean all the files off my iMac as I wasn't using it as my primary computer anymore. After deleting the files, I used Disk Utility and used "erase free space" with the 7x option. I also emptied the Trash folder.
    When I checked the HD, I found:
    Capacity: 297.77 GB
    Available: 4.68 GB
    Used: 293.09 GB
    This makes no sense to me, since there is very little on the computer (some applications). Also, before I started, I know there was about 260 GB available.
    I'd appreciate some advice on how to "free up" the available space that I know must be there.
    Thanks!

    Hi, sounds like the secure erase didn't finish maybe & left a big invisible file on there.
    How much free space is on the HD, where has all the space gone?
    OmniDiskSweeper is likely the easiest/best, and is now free...

  • System Won't Reboot Proper After Running "Erase Free Space" in Disk Utility

    Thought I'd run it to see what happened.
    On an 80gb HD with 35gb free, I was told I was running out of free space partway through the erase, program then quit. Kept system going for about two days without problems, then shut it down for a day. When I rebooted a few hours ago, it seemed to take forever to do so, followed by a dim perpetual blue screen which I couldn't brighten via the keyboard. Waited 20 minutes for screen to resolve into my desktop; alas, no such luck. Rebooted a few times, no change.
    17 pB @ 1.33ghz & 1.5gb RAM   Mac OS X (10.4.7)  

    One of the first things I tried: no effect.
    Booted on the MacOS X CD and ran disk utility and it found errors, fixed them, rebooted from the hard drive and now I get a perpetual grey screen with the li'l rotater. Zapping doesn't do anything this time either.

  • External Hard drive shows no space after failed "Delete Free Space" from Disk Utility

    2009 13" MBP running 10.6.8
    I was clearing out a section of my external to clean it of a former client's information. The operation worked fine until it got to the "create temporary files" where it got hung for several hours. Forced quit D.U. and rebooted my machine. Now the external only shows 5MB when it should be closer to 150MB.
    I have run the the following script in Terminal to show hidden files:
    defaults write com.apple.finder AppleShowAllFiles TRUE
    killall Finder
    Not sure what files to delete.
    Should I run:
    sudo rm -f /var/root/Library/Caches/TemporaryItems/*
    Will this delete the temporary items in my external or only my HD?
    Any tips would be greatly appreciated!

    Fixed it! I downloaded WhatSize and found the temporary files. Deleted and retrieved all my space!

  • Lost audio files after sync but storage space unchanged

    I had 4GB of audio files in my iphone which was erased after syncing. But my memory is unchanged. So I can't sync and add it on my phone again because it says I don't have any space. Is there any way I can reset the phone and just start over.

    Welcome to the discussions,
    here's how to restore the phone: http://support.apple.com/kb/HT1414. Set it up "as new phone" and you start again.

  • Disk Utility Error - Secure Erase Free Space failure

    I have encountered a problem which I can't solve: I've used the secure erase feature to wipe unused parts of the disk before without problem. Now I get the following error message each time I try to use Disk Utility to do so:
    "Secure Erase Free Space failed
    Secure Erase Free Space failed with the error:
    Could not create temporary file"
    I tried it with the hard disk on the computer, my external backup disk, and a USB thumb drive. Same error message in each case.
    If anyone knows the solution I would appreciate the help. I've scoured these fora and the internet to no avail.
    Thanks.

    Tried booting from another hard drive and running Disk Utility Repair Disk? follow up with Disk Warrior after that.
    I would just do a full volume clone, reinitialize, and restore.

  • Secure Erase Free Space

    Secure Erase Free Space Failed
    Secure Erase Free Space failed with the error:
    Couldn't create temporary file.
    Hello, I own a 15" Macbook Pro 2011 Late model but I recently replaced the hard drive with SSD and upgraded the memory to 16gb. It was working fine for about 4 months and now sometime it freezes while browsing or even opening an application. I had to restart the macbook and sometime I would get a white screen. I was able to get by the white screen by restarting constantly. I am afraid to shut this macbook down and end up with a white screen. While I got through the white screen, I was able to use the disk utility and got this message when I was cleaning up free space. My SSD has 431.82 GB free of 478.89 GB. Can anyone tell me where do I locate the temporary file or is there something else I need to fix? Please let me know. Thank you.

    I understands that.
    But heres what Im talking about

  • Erased free space in Disk Utility, and after it finished it kept a DMG there.

    I erased free space in Disk Utility, and after it finished it kept a DMG there called "DeveloperDiskImage.dmg", why is it left behind? can it be deleted? how? if erasing free space is supposed to help get memory and remove all the files truly, it shouldnt be creating anything, it created a DMG at the start, but it went away, after a hour and a half it made the DeveloperDiskImage, i went to eat dinner and when i came back it was done but that was left.

    Delete it. Erasing the free space isn't supposed to free up any space; it's there in case someone deleted a file insecurely when they meant to securely delete it.

  • Kernel panic after "Erase Free Space" No end in sight

    I did an "Erase Free Space" in disc utility. After seeing it through to about 90% complete, I went to bed. When I got up in the morning my fan was whirring away and I couldn't wake up the computer, so, using the power button, I shut it down, then turned it back on. Now I can't get into OS X (I see the message "You need to restart your computer..."), I can't boot from CD, and I can't boot in safe mode. All I can do is run the hardware test (after booting while holding "option" key), which tells me everything is fine. My only theory is that my hard disc was locked during the erase free space operation and since I have been unable to properly reboot the system, it can't be unlocked in order to boot from CD or open OX X. Any thoughts? I've been without my mac for a week now and am growing increasingly desperate. Thanks.

    ..."When I erased free space, instead of writing zeros to the free space, it essentiall wrote ones [...] I can start up in single-user mode and am contemplating formatting the drive and reinstalling OS X, if I can't just erase induvidual files."...
    How exactly did you figure this out - what exactly are you seeing with respect to "individual files"? I thought the procedure with erasing free space used by OS X was basically to fill the free space with a big file, and securely deleting that file, but things may have changed. Your reference to writing ones and individual files is giving me an impression of many small files instead of a single large one - i.e. something that is different from what I would have expected.
    I would have suggested looking for a file called EFTFile1.sparseimage or EFTfile2, or something like that while booted in single-user mode. It would have been in your user's "~/Library/Caches/TemporaryItems" folder, or in "/private/var/root/Library/Caches/TemporaryItems" and been as large as the free space was before starting the procedure. It should have been deleted automatically if the process had succeeded but if the process was interrupted, it would have been left on the drive taking up all of the space. Normally, you should be able to 'rm' it manually after mounting the drive as writable (with the usual warnings about executing commands in single-user mode), but since the situation may be different in this case, I don't know if this suggestion applies...

  • No Hard Disk Detected after Erasing Free Space

    Hi ,
              First I will explain the problem, I will be grateful for your help to solve it as immediately as possible. Thanks in advance !
    I have a MacBook Black since 2007, with system specification, 160 GB Hard Disk, 1GB RAM, 2.16 GHz Intel Processor. I had a OS X 10.4.11 Tiger version. I need to upgrade it to 10.6 Snow Leopard. I bought OS X 10.6 DVD Snow Leopard version from Apple Store.
    Last night, I save my all the data on external HDD, and tried to install 10.6, and it is installed over 10.4.11 with everything on the internal 160 Hard Disk. I did not want like that. I again started the installation process, I went to Disk Utility, I did some thing with partition, i.e. I created again 160 GB partition. Then I wanted to format, Then I saw some Erase Free Space and only Erase also, I click on Erase only, it is finished in seconds. but I was not satisfied. I saw button Erase Free Space then I click there, then , it takes about 90 minutes, and at the end, I saw a failure message that it could not create the temporary file or something like that I forgot what was written, however, it was a failure message ( it is failed to create etc ) .. ,
    Then I saw, that there was nothing in the disk utility tool except the installing 10.6 Snow Leopard DVD. I was shocked, what happened.
    Does some body could help me in this regard. How can I get the internal HDD with installation DVD ? What should I do after to erase everthing from my internal HDD, I mean , there should be nothing on it ..,
    A big THANKS to you to solve this problem.
    Best Regards,

    Yes, I just played with Disk Utility, and in the end, I found nothing.
    With the installer DVD, when I came upto Menu List, I click on Apple in the upper left corner, There are many menus but in grey, I can't click on them, e.g.
    About This MAc
    Software Update...
    Mac OS X Software ...
    Logout ...
    I can't click them ,
    Just for Info, In the Utilities Menu, the list is as below,
    Startup Disk ..
    Reset Password..
    Firmware Password Utility
    Disk Utility
    Terminal
    System Profiler
    Network Utility
    Restore System From Backup,
    Here I click on the System Profiler Menu,  After that, I go into deep, there are hardware list,
    In ATA ... it shows only  MATSHITADVD-R UJ-857E .. in detail it shows about the installer 10.6 DVD
    and
    In Serial-ATA .. it shows  Intel ICH7-M AHCI ..
    I did not find anything about internal HDD of 160 GB.

  • Help please - message after using the Erase Free Space function in Disk Ut

    Please help. I've been using my Mac Mini for 6 months and decided I wanted to securely erase previously deleted files, and found the Erase Free Space facility in Disk Utilities. So I chose the option "7-pass Erase of deleted files", and left my Mac Mini to do its business.
    At the end, I got the message that my startup disk is full, but ignored that message because I understand that's normal when free space has been deleted.
    After doing a Restart, things seem to be running smoothly, but I have a Warning message which reads
    Warning. The following disk images failed to mount:
    Image: EFTFile1.sparseimage Reason: corrupt image.
    What does this mean, please, and what do I have to do, if anything?
    I'm completely new to this, so please explain clearly.
    Thanks everyone!!

    Hi again, i've resolved the problem, thanks. It was my inexperience that was helping confuse the issue.
    Sorry to have taken your time. Thanks again for your input.

  • Disk Utility shows incorrect free disk space after erasing hard disk

    Hello.
    A few days ago, I tried to re-install my Mac OS and both Snow Leopard and Lion got the same problem. Before the re-installation, I erased the hard disk of my MacBook (late 2009) and the SSD of my MacBook Air (late 2010) - but after erasing the disks, the disk utility continued to show more or less 5 GB of used disk capacity, although the disks should have been cleared entirely I think.
    After installing Snow Leopard or Lion, Finder showed as much free space as I usually expected it would, but Disk Utility still stated 5-10 GB less. For example:
    MacBook: Finder shows 17 GB free, Disk Utility 6 GB free
    MacBook Air: Finder shows 26 GB free, Disk Utility 19 GB free
    There are 2 problems:
    1) I need the original disk capacity. Think everybody agrees with that wish.
    2) More important: The MacBook should still get a Bootcamp partition (unfortunately, that's necessary for my university's software.. :s): With 17 GB free space, it would work - but 6 GB doesn't.
    I would be very pleased if somebody could help me. I searched the web many times so far but didn't find any real solution.

    The available disk space reported in finder is totally wrong.
    Even if it accounts for the local snapshots. In my macbook air it shows 120 Available in finder which is just 1GB less than my SSD capacity.

  • Start up and shut down is slow after erasing free space using disk utility?

    I went to Disk Utility, clicked Erase, and then "Erase Free Space." When I saw that it was going to take 1 hour and 30 minutes, I tried closing disk utility. It wouldn't let me exit, so instead I pressed "Skip." But when you hover over the "Skip" button it says, "Erase all data and reformat the disk."
    I'm wondering if the fact that I pressed the skip button has anything to do with my computer shutting down/starting up A LOT slower now. If so, what can I do to fix it?
    Thanks!

    Just wanted to give an update. I called Apple and apparently, you shouldn't empty the free space using disk utility while you're logged in. I had to insert the Installations CD and press the "C" button while my computer restarted, and used Disk Utility from there. My start up and shut down speed still isn't exactly the way it was before, but this definitely made a difference.
    Thank you to those who replied to my question!
