OS X :: Disk Utility - How To Erase Free Space - How To Recover

May 3, 2009

I just ran the Erase Free Space thinking it would help me with a bootcamp issue.

I had 70Gb free and I stopped it when I noticed i had 30 Gb free left. So I just lost 40 Gb of hard drive space. What happened? is there anyway of recovering it or did I just make a huge mistake.

Applications :: No Disk Space After Failed Disk Utility Erase Free Space?

Dec 15, 2010

I'm having a pretty serious problem. I attempted to erase the free space on my HD, as I do from time to time, except this time it appeared to hang/freeze at the end, when it gets to the part where it creates a temporary file. I waited for several minutes and it didn't move. I tried clicking the skip button, but that did nothing either, so I force quit Disk Utility.

The problem is, it left the disk at "Zero KB" of free space, effectively making my computer inoperable. I was in the process of studying for a huge exam tomorrow, and am currently flipping out.

If it matters, I'm on a Macbook Pro 2.33 GHz Core 2 Duo, running 10.4.

I really don't want to have to reinstall the OS and import the old files, but my real fear is that I will have to do a fresh install of the OS.

Mac Pro :: Using Disk Utility Erase Free Space?

Feb 10, 2009

i was Erasing Free Space in Disk Utility, after a while I needed to Force Quit another program but I mistakenly quit Disk Utility and now it says I only have 3.1 GB space available when it should be around 270 GB available. I'm sure Disk Utility said it was 'Creating Temporary File' at this time this happened.

I'm now also getting a message which states I need to clear out space on my start up disk.

OS X :: Erase Free Disk Space Function Error?

Oct 18, 2010

I interrupted the erase free disk space function and I ended up with zero kb of space left on my HD. I have tried to find the EFTFile1.sparseimage file to no avail. I have also tried deleting other files in order to "flush out" the trash and hopefully open up the rest of the space, but that didn't work either.

OS X :: Disk Utility Showing Low Free Space

Jan 6, 2009

I am using a Mac Mini, Which is having a capacity of 74.2 GB. Hardly I made use of 15 or 16 GB of that. As I felt some slowness, I tried running "Disk Utility". Recently I found that the free space is only 2.4GB, instead of around 55GB..

Disk Utility is showing
USED SPACE :71.8GB

If i am calculating all folders in "Machintosh HD" (Application, Library,System, etc..), it wil come around 14-15 GB only.

OS X V10.7 Lion :: Disk Utility Shows Incorrect Free Space

Jun 11, 2012

The Finder window shows that I have 302GB of harddrive space remaining, out of 500GB. The Activity Monitor and Disk Utility show I have 240GB space remaining, and my System Profiler shows I have 239GB remaining. I just deleted a bunch of old TV shows off of iTunes (about 40GB worth) to open up some space, but only the Finder changed (up to 302GB from 260GB) but the Activity Monitor, Disk Utility, and System Profiler haven't changed. 

Now, I'll assume the Finder is showing the correct amount of space, but I'm wondering why the other utilites are showing the incorrent amount of space. I have a feeling maybe something was screwed up when I created a 50GB Windows 7 partition through Boot Camp a couple months ago. 

I've attempted to Repair Disk through the Disk Utility and it says everything looks fine. Any solutions to this minor inconvenience? Or at least an answer as to why this is happening?

MacBook Pro, Mac OS X (10.7.4)

OS X :: No Free Space - Erase Free Space Interrupted

Mar 20, 2009

Yesterday I apparently interrupted Disk Utility when it was erasing free space, which was far bigger than the used space on my beloved black Macbook. Apparently the free space, because the program was interrupted, is seen as one honking big file.

This morning, the disk utility tells me that I have zero free space. Verify says I do not need repair. I checked because of all my sudden problems (I am unable to save anything to the laptop, unable to cut-and-paste . . . and unable to erase free space again since there officially isn't any, etc.).

Trash is empty.

I tried (based on advice in another thread) to reboot with the installation disk so as to use its disk utility program, but the installation disk menu offers "install" etc. but not (as far as I can tell) just access to its disk utility.

I plugged in my Timemachine external drive [WD MyBook], but the most recent "save" there has the "restore" button greyed out. That's scary.

I'm willing to do a complete re-install if necessary, but I hope that one of you has a simpler solution that will simply get my free space back.

OS X :: Skipped Erase Free Space, No Space On HD?

Apr 23, 2009

I managed to interrupt the computer when I selected the "Erase Free Space" option. I had 0GB left on the computer and had to cancel almost all of the applications. I Googled and found that /var/root/Library/Caches/TemporaryItems should locate the file when entered in Terminal, but whenever I try that, it just says "Permission denied." It only asked for a password once, and when I tried entering it, it said that there was no such file. I located a few other temporary files and deleted those, and also tried making empty folders on the desktop to empty the trash. It freed up 6.7 GB, but there's still a lot of space missing. I'm not sure what else to try or how to get the space back.

OS X V10.7 Lion :: Recover Free Space For An Existing Partition?

Mar 14, 2012

Up until recently, I had my MacBook Pro's hard drive in 3 partitions: 2 with Mac OS X, and one as a Bootcamp partition.  I recently decided that I no longer needed to Mac OS X partitions, so after backing up all the files in one of the partitions I went into Disk Utility and deleted that partition, hoping I could expand the other one to take the free space.  Unfortunately, now I have this area listed as "free space," and while I can make another partition in that space, I can't expand my existing partition to take advantage of it.  Is there a way for me to get this space back, or perhaps merge 2 partitions together? I'm just afraid of losing ~400GB of space.

MacBook Pro (15-inch Early 2011), Mac OS X (10.7.3)

OS X :: Cannot Erase DVD's In Disk Utility

Jan 28, 2008

I am having trouble erasing DVD+RW discs. When I insert a used disc and try to erase it in Disk Utility, the process seems to complete almost immediately, ending with OS X asking me if I want to mount the inserted blank disc in Finder. However, if I eject the disc and put it back in, everything is still on there. (detail: When erasing, there is usually a short interval where a striped progress bar is shown, after which a "normal" progress bar is slowly filled as the disc is erased. However, for me only the striped progress bar is shown--the "normal" progress bar is skipped--and then OS X says erasing is done.) If instead of ejecting the disc I choose to go ahead and burn something as if Disk Utility has actually erased the disc, I get a laser power calibration error.

Applications :: Utility To Wipe Free Space On Macbook

Jun 8, 2010

I'm fairly new into my mac. Today I have been searching for a utility to wipe free space on my macbook. I'm looking for something open source/freeware. When I was using Windoze I used Eraser by Heide. I can't find a thing out there. Oh, and I've done a search here in the forums and after looking through multiple pages I haven't found anything that meets my needs. Sorry. I'm pretty frustrated. And pardon my ignorance in all things Mac.

Software :: Deleting Everything Before Using Disk Utility To Erase All

Aug 31, 2010

I am selling my 6 months Macbook pro and I would like to delete everything very securely. I would normally do a fresh install and then use disk utility to erase all date on a 35 pass. However I do not have the installation disks. I am not the best at using a mac but could someone tell me everything I have to delete and the steps I must take before I do a 35 pass erase in disk utility? I have noticed in console that I cant delete 'Diagnostic and usage messages'. I have gone through Finder then deleted the applications and gone to application support and deleted what I have seen but is there anything I am likely to miss being a non techy guy? I don't want to leave anything at all on the mac in the slightest.

Windows On Mac :: Using Disk Utility To Erase And Make New Partition

Feb 27, 2010

My Computer: 2.8 GHz intel Core 2 Duo Mac, running OS X Ver. 10.5.8. I've partitioned my hard drive before, but in order to get more space on my Windows partition I have made a disk image using a program called Winclone. I also backed up important files to my external hard drive, and then used disk utility to erase and make a new partition so I could restore the Winclone disk image I made and have everything back. What I'm concerned about is I've been waiting for this new partition (65 GB) to finish being made and its taking a while. I read that if you stop the process it could damage the OS X side and you could lose all your files.

I started to run time machine about 10 minutes ago and set the destination to my external drive for backup (Its a huge drive, it can hold 650+ GB so I'm not worried about running out of space.) Do I stop Disk Utility and risk it? Do I let it run? Do I kiss my computer goodbye and pray that Time Machine backed everything up right onto my external hard drive? I don't know if Time Machine is working correctly because I started it after I began to partition my hard drive. What to do. Should I let Time Machine back everything up, the disconnect my external and end Disk Utility?
