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.

When using the Disk Utility free space wipe to wipe sensitive data (using the 7 times option), I thought that would be sufficient.
I was wondering though, does the free space wipe option also wipe the slack files on the hard drive? Is this even an issue for a Mac? (I know on Windows the slack file needs to be wiped for a completely secure erase, right?)

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.

Model - Macbook Pro 2013 Retina
Issue - In the disk utility, the free space under partition and Macintosh HD do not reflect on each other. There is the difference of about 10GB between these two.

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.

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.

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.

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?

I only have like 8 gb left on my macbook's hard drive. Are there any programs I can run that will defrag/free up space? How much does Apple Store typically charge to upgrade a hard drive? How easy is it to do myself?

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.

I have a pdf file with lots of high-res photos in it. Is there a good way to reduce the file size while keeping the photo quality reasonable? A free utility that allows users to adjust the level of photo quality would be great. Under Preview, I tried "save as" and then "Reduce File Size" with Quartz filter. The file size was reduced by 1/10 but the photos did not look good.

Let's say I find a great video on the internet. Is there a free and legal way to separate the audio file only? Is there a software program that will do this?
And if there is nothing that's free, do you suggest buying a certain music/mixing program out there that has this capability?

I've currently got a Windows XP partition and a Mac partition. Thing is, I allocated too little to Windows XP, just about 20gb. I don't want to go through the hassle of installing the whole thing again so is it possible I free up some space in my Mac partition and just use some partition software in Windows to extend it's size?

I broke the disk into two logical volumes. In one volume, had an operating system. In the second volume of stored programs. Then I needed to increase the size of the system drive.What I did:1. Booted from installation disk.2. Remove the second partition.3. Increased the size of the first (system) disk.4. Check the disk and partition for errors.

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.

I've decided to switch my current HDD with a bigger one. I currently got 160gb wich is a little bit tight. I also have a WD Passport 160gb but I use it as a TM Backup. I don't really know if I need 7400 RPM. I use frequently Adobe PS CS3 and MSN, iTunes, Firefox... I also plan on getting some games like COD4 and things like that. So far here are the drives I've been looking:
5400RPM 320GB WesternDigital @ OWC for approx. 75.99$CA: [URL]
7200RPM 320GB WesternDigital @ NewEgg.ca for 84.99$CA: [URL]
5400RPM 500GB WesternDigital @ OWC for approx. 112.62$CA: [URL]
Right now, my 160gb contains 148gb of stuff and I've got some movies on my brother's external HDD. I don't know if 320gb would be enough or if I'm gonna be tempt in 6 months-1 year on getting more space?

I would like to gain back some space on my Macbook's HD. I would like to:
1) Burn all the photos and videos on DVD's. Re this, once burned, I'll delete them from the HD, via iPhoto.(show files, etc.) What would happen with the events? Say that, in the future, I want to import 20% of the photos with their corresponding events (already deleted from iPhoto): is this feasible?
2) Is there an app within Leopard OS (not Snow Leopard) that would allow me to change photo and video size, all at once or not. (batch processing?) Videos and photos where imported within iPhoto app.

I'm about to order a Macbook Pro and I'm undecided between a regular 500gb 7200rpm HHD or the 128 SSD. I've heard the SSD is fast but I'm afraid it might not be enough space. Typically, hard drives actually have a little less free space than the number it indicates. For example, a 500gb might have about 460gb of free space.

I clicked Disk Utility, then Macintosh HD and moved the mouse a bit leftside; at that point, I discovered that I can't click "Erase free space", but it shows "Erase free space not available on this type of disk drive". I don't know why it happened. Also, my disk storage is full though I never installed many memory-consuming applications and media files. It just shows "others" that dorminates the whole memory storage.
