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,
Imran Khan

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.

Unusual hard disk activity after "Erase free space"
I have two partitions on my hard disk - a small partition for the system software and a big partition for everything else. A few days ago, I backed up a few files from my big partition and then used Disk Utility "Erase free space". Since then, my hard disk is behaving oddly. I can hear it, as if it continuously reading and writting data. At first, I thought it was an auto-update in progress or some sort of automatic system maintenance. But the odd behavior never stopped. I scanned my files with an anti-virus software - nothing wrong. I scanned my files with Disk Utility - nothing wrong. I used Onyx to check the system - nothing wrong. I even erased and reinstalled the system software - no changes! So what could possibly force my hard disk to behave like that? Is something messed up because of "Erase free space"?
You could run fs_usage
To view file activity for all processes with the fs_usage tool, you would enter the following at the Terminal prompt.
sudo fs_usage
If you wanted to limit the display to files accessed by a particular process, you could redirect the output through the grep tool. For example, to display file behavior for the TextEdit application, you would enter the following at the Terminal prompt:
% sudo fs_usage | grep TextEdit
Once your application finishes launching, stop fs_usage by typing Control-C in your Terminal window.
Look for all writes. Might be mdworker (Spotlight)
Try reindexing Spotlight by dragging the HD icon into the Privacy window. Leave it there for a minute and remove it using the minus button. -
My external Lacie Quadra hard drive accidentally switched off in the middle of "erase free space", and when I switched it back on Disk Utility was hanging. So I Force Quit Disk Utility and restarted it. Now when I try to erase I get
"Secure Disk Erase failed with the error: Couldn’t unmount disk."
But "erase free space" seems to work...
What can I do? I'm erasing as I'm giving the drive to someone else and I wanted to wipe it clean.
Also should I use "erase" or "erase free space" if I want to wipe the drive clean?
Please help!Sorry I don't really understand.... there are no partitions on the drive. How do I repartition it?
And should I use "erasing free space" or "erase" for wiping clean my drive of everything? Erase seems to be faster last tiem I tried.
Thanks! -
Disk Utility Problems - Erase Free Space
Today I decided to use disk utility to "Erase free space " on my MacbookPro. During the process it said it was creating a temporary file!
This took about 2 hours then the application stopped responding, so I clicked skip and ended up doing a force quit!
Unfortunately, this task did not complete but it seems to have added over 10GB to my hard drive.
Any ideas how I can find the file and delete it or should I consider restoring my Mac to yesterday using my Time machine backups.
Thanks
KeithHowever, does anyone have any advice on how to use the "Erase Free Space " Utility
This option should only be used when you've insecurely deleted a file you meant to securely delete, and should not be used on a FAT32 drive with 4GB or more free space.

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! -
HT3680 How to get my free space back after quitting the disk utility's erase free space
Hi,
I started the DU's erase free space--fastest way method. When it almost completed, I had a pop up that said that I need to free up disk space.
So then i was flustered enought to just quit the program because I didnt want to free up disk space and I was frustrated.
Not knowing it would still keep whatever it was that took the remaning disk space on my Mac.
How to I get this removed so I am back to before?Sorry I don't really understand.... there are no partitions on the drive. How do I repartition it?
And should I use "erasing free space" or "erase" for wiping clean my drive of everything? Erase seems to be faster last tiem I tried.
Thanks! -
Disk Utility's "Erase Free Space" screwed me over big time. Help Please.
Hey, I have a serious dillema. I free'd up disk space on my mac by transfering files to an external drive, and then used Disk Utility to erase unused disk space to do a thorough cleaning. Now it seems that out of thin air, Disk Utility said my Mac is out of disk space....it basically filled up my hard drive with 370GB's of god knows what.
Here's exactly what I did, step by step:
Basically, I wanted to clean up my hard drive a bit, as I was using about 500GB's out of my 750GB HD (on my MBP 10.6.8)
-Before I did this test, I did a verify + repair disk permissions, I also organized my computer's files... and just to be safe, I booted up from the D key so I could do an extended hardware test to see if everything was running smoothly. I then zapped the PRam. This was my pre-clean maintenence check.
-Then I transferred all of my files onto my external disk.
-After this was done, I dumped the files (that I used to transfer to my External) into the trash bin.
-I emptied the trash bin.
-Now I free'd up hundreds of GB's of space.
-It said that I had 376 GB's of free space in my hard drive. Yay.
Now here where it all went wrong:
-I heard that if you go into Disk Utility, and click on "Erase Free Space" that it goes over all the delted files (that aren't actually permanently deleted) and it permanently deletes them so that it frees up all the loose ends on your mac. I didn't want any ghost files, or any old installs or whatever...so I thought, yes.
Now...Disk Utility was doing this for me....and 2 hours later....it said that I was out of disk space. Disk Utility froze around the 90% completion-mark when it was "Creating Volume" (or something like that) and I had to quit Disk Utility.
Then, I exited....went onto my desk top and checked my Hard Drive.
It said that I had ZERO KB's available.
My hard disk was completely full. How is this even possible? I had 376 GB's of EMPTY space 2 hours earlier.
I tried to go into all of my files to see if there were any duplicates made..I checked terminal to see what went wrong, I checked console...I searched, and I searched...and nothing.
What. The. Heck.
Can someone please, please help me?Boot from your installation disc, erase the internal drive in Disk Utility, reinstall OS X, copy the files from your backup, and then run Software Update.

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.
iMac G5 (with iSight) Power PC 2.1 GHz Mac OS X (10.4.8)..."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... -
Automatically hard disk is loosing its free space space
My macbook pro is automatically filling it`s free space....Now it`s showing "your start up disk is full"....
But i calculated the total files and folders, am using only nearly 200 gb...but my Harddisk have 320 gb capacity
I tried deleting some files of 8 gb....then it`s show 8 gb free space available ..again after sometime it shows "your startup disk is full" and available free space will below 1 gb.Emptying trash is only recommended, if you are certain the data in the trash is no longer needed, or if uncertain, you have it backed up elsewhere. Many people drag files to the trash assuming it is safely stored elsewhere. One of the most common misconceptions is that items sent to the Dock or Sidebar are safely stored. This is not true, and if someone were to trash a file they dragged into the Dock or Sidebar, it would be gone for good unless backed up elsewhere as the full file and not just an Alias (Shortcut).

My start up disk is full. I have been through my computer and erased a lot of music and video to free some space. I then went to disk utility to erase free space and find that the erase free space button is pale and therefore won't work. Nor can I select or deselect MacOS extended journaled.
Advice please?!Recovering Disk Space
If you have less than 20% disk space then it is time to roll up your sleeves and search for what you can delete and what you can offload to another disk.
If you have less than 10 GB you definitely need to delete or offload some files or purchase a lager disk or SSD (see below). You may want to maintain at least 20 GB of free space so when your disk starts filling again it will have some room before it hits that 10 GB mark again. More headroom is better. If you let the space fall much below 9 GB you might not be able to boot your machine.
Initial easy steps to gain disk space:
- Delete all files in the Downloads folder.
Empty the Trash.
- Start iPhoto.
Empty its trash.
Restart.
- Restart in Safe Mode:
Restart the computer.
As soon as you hear the chime press and hold the right shift key.
Be patient. Hold it down until you see the Apple icon.
Empty the trash.
Restart in normal mode.
- Delete "Recovered Messages", if any.
Hold the option key down and click "Go" menu in the Finder menu bar.
Select "Library" from the drop down menu.
Library > Mail > V2 > Mailboxes
Delete "Recovered Messages", if any.
- Empty the Trash.
- Restart.
- Re-index your system disk (Macintosh HD):
http://support.apple.com/kb/ht2409
Time Machine Snapshots:
If your disk is 80% full that is normal. Time Machine uses up to 80% of the disk space for local snapshots. To get rid of these snapshots simply plug in your Time Machine backup drive and run a backup. See About Time Machine's 'local snapshots' on Mac notebooks: http://support.apple.com/kb/HT4878 and What are Local Snapshots? http://pondini.org/TM/30.html .
If you are concerned that the “Other” category of disk usage is taking too much space and for information on deleting files then look here: https://discussions.apple.com/docs/DOC-5142
Backup:
Run a Time Machine (or other) backup since you are about to delete and move files and you may need to recover from any inadvertent mistakes or decisions. You will need one external hard drive for your Time Machine (or other) backup and a second if you plan to offload some files. (See suggestions for where to purchase hard drives at the end of this message.)

Methodology to protect your data. Backups vs. Archives. Long-term data protection:
https://discussions.apple.com/docs/DOC-6031
Deleting files:
Then use the free application OmniDiskSweeper http://www.omnigroup.com/more to explore your volume in descending order by size so you can attack the problem from the top down, deleting the largest unwanted files first. Delete with caution and do not delete any system files. Remember to empty the trash after trashing the files.
Additional reference on freeing disk space:
http://pondini.org/OSX/DiskSpace.html
Offloading files:
Consider moving some of the no-often-used large files or directories to an external disk. Use ODS again to find them. As noted above this will be at least your second hard drive. Your first one(s) is/are for your Time Machine (or other) backup(s). Do not offload files onto a Time Machine disk.
Format the second drive as Mac OS Extended (journaled). Using OWS to find large files/folders and copy them from the system drive to the external hard drive and delete them from your internal drive.
Then > System Preferences > Time Machine > Options… > Remove the offload HD name from the exclusions list.
Now both your system disk and your external offload disk will be backed up onto your Time Machine disk.

Hardware — Bigger disk/SSD:
If your system has upgradeable storage then if you are still tight on disk space consider larger storage. If you have a disk consider replacing it with a one TB disk. Check out a one terabyte HGST 7K1000 7200 rpm, SATA III drive from OWC http://eshop.macsales.com ($100). If you have an SSD consider increasing its capacity to 240 or 480 GB. A standard 240 GB SSD would cost from $200 to $280. See OWC and Crucial: http://www.crucial.com/ for options. OWC sells 120, 240 and 480 GB SSD upgrades for MacBook Airs. A 240 GB upgrade costs $265. http://eshop.macsales.com/shop/SSD/OWC/ . If your Mac is under warranty or AppleCare replacing the SSD will void the warranty.

Erase free space function of Disk Utility
Hi all,
I've read some of the discussions about the problems that can result from using Disk Utility to permanently delete items that have been emptied from the Trash (and which were not "securely" emptied). Before I use the Disk Utility function, I'd appreciate some advice:
1. I have an iBook G4, running Mac OS 10.4.11. My hard disk has a capacity of 55 GB with 30 GB available. Does the capacity available matter, and is mine sufficient?
2. Will I be given an option on overwriting the files 0, 7, or 35 times, and should I choose 7?
3. How long is this operation likely to take?
4. Shall I just start the operation and then not touch the computer for a few hours, or overnight, and hope for the best??
5. A final question (a stupid one, I hope!) -- only those files which were put in the trash will be deleted, right?? Not anything else?!
I am quite worried about taking the step because, if things go wrong, I won't have a means of contacting the Apple support forum as this is the only computer in our household.
I am planning on giving this iBook to a nephew in six months or so, and am gradually cleaning it up for that purpose. But I'm not ready to "zero it out" entirely and I am hoping not to lose anything currently on my hard drive following the "erase free space" operation, or to have to reboot from the original CDs.
If the operation is successful, I will then remember to always use the "Secure Empty Trash" option when deleting future files. I'm assuming that, if I do that, I should have no concerns about giving the laptop away -- correct?
As you can tell, I'm not very computer savvy, and I'd be very grateful for help. Thank you!Open Disk Utility, Highlight your drive on the left, then on the right bottom you'll see Verify Disk & below that Repair Disk grayed out because you can't reopair the HD yo're booted from, if it does need Repair...
1. Insert the Mac OS X Install 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. Select your Mac OS X volume.

Disk Utiility Erase Free Space Inconsistencies
About a week ago I used Disk Utility to erase free space on my HDD. I set it to the 7 pass option and ran it in the evening before I went to bed. When I got up in the morning the task had been completed and Disk Utility indicated it had taken 2 hours.
Last night I did the same thing, but this morning I found that Disk Utility was still running the task on my iMac. The little progress bar indicated only half of the job had completed and it said estimated time 3 hours -- this is after it had already been running 8 hours.
I have about 70GB free space.
Why is this taking so long, particularly considering it did the same thing in 2 hours a short time back.You might have some disk corruption. I suggest you back up your important files to a different disk first. Then repeat what you are trying to do and see if the console manager shows any errors or just get a copy of Disk Warrior and run it.

Disk Utility: Disk Scrubbing ("Erase Free Space")
Hi,
I've logged in case 113969827 the following observation:
In a Macbook 10.5.6 using Disk Utility to Erase Free Space
(Disk Utility / Erase / Erase Free Space) with 7-Pass or 35-Pass
Erase on a / partition with 113GB free of 200GB of a 232GB drive
which is Boot Camp partitioned, the other 32GB going to a
flawlessly-running Windows XP, rarely used, the following
issue happens...
The free space (87gb) goes to 0gb.
Has anyone else seen this?
Thanks.
Message was edited by: cracraftHey,
Talked with Apple in Texas, Indiana and Silicon Valley on this one
as well Josh...
The bottom line executed so far is:
Shutdown Mac OS X
mount -uw
/usr/sbin/fsck -fy
shutdown -r now
Finder
Disk Utility
Erase / Erase Freespace
Select least secure option and run
Wait until Disk Utility is final (no timing messages)
The above completed okay and your advice to "wait it out"
was right on the ball.
Next, I need to do Erase / Erase Freespace 7-Pass overnight
and then a 35-Pass tomorrow.
The reason I want to do all this heavy "assurance" of deleting
is that if I am required to send this notebook back for the cpu
fan issue, then I certainly want privacy for my disk. But on second
thought, upon receipt, I could just go to the local Apple store and
swap out the disk from one and place it in the new frame and
bootup, retaining my data.
Anyway, thanks for your input today as well as Richard in Indiana,
Matt in Texas, Matt in Silicon Valley.
(There were no errors in the fsck btw though it did say the FS was
modified... odd.)
Stuart
P.S. One would want to do more than the drag-and-drop to the Trash
with Empty Trash btw. I don't think those are assured from undelete
by savvy wizards or other operatives... whereas, 35-pass certainly is
completely secure, assuming the implementation at Apple doesn't
have a backdoor of some kind...
I'll keep this thread updated after the 7-pass / 35-pass which I am
sure just requires extra patience, as you indicated. Thanks! -
Disk Utility - Erase Free Space-what does it really do?
Hey Forum,
I am using mac os 10.6.4 on my macbook and i have a doubting question for quite sometimes, what does disk utility erase free space feature really do? Does it gives you more free space? or what? I know it prevents the recovery of deleted files but i want to know what more it does and do not do? Like, now my hdd free space kept increasing and decreasing, by a few 100 mbs or 50mbs etc, so do i erase free space so to solve this problem? Ok, i do not only want to know does it solve the previous problem, but also the questions stated in the whole long paragraph i have wrote. If you know anything related to disk utility's erase free space, feel free to tell me!
Pls help me, I need you guys' help!
Thank you.
Regards
Ala.Erase free space simply writes zeros over the space occupied by deleted files to prevent data recovery. That's all it does. It does not give you extra disk space.
Your disk space goes up and down a bit because the system creates temporary files and logs which take up space, such as the Safari cache. You can clear these file using a utility like Onyx (which is free) -
Need help with the "Erase Free Space" disk utility
When I use Disk Utilities to Erase Free Space (I use the single zero mode) I get a message telling me,
"Your Startup Disk is almost Full,
you need to make more space available
on your startup disk by deleting files."
This occurs about 90% of the way through the process (based on where the blue bar is at the time) during the "Creating Temporary File" portion of the process. I know from past experience that I will remain in this portion of the process forever unless I press the "Skip" button to complete the process.
My questions,
1. What is the startup disk and why is it full?
2. What should I do about the Your Startup Disk is Almost Full warning?
3. Is my computer actually talking about "regular" disk space (I currently have about 9GB of 80GB free but have seen this warning with 30GB available as well).
4. When I press "Skip" and the blue bar continues to complete the process, have I actually erased free space?
PBG4 15" 80GB HD 1GB RAM Mac OS X (10.4)The Disk Utility does the erase by creating large temporary files, writing to them, then deleting them. While doing this, OSX may notice the lack of free space on the disk. This is normal, but could cause problems if you are also running some applications that want some disk space. If you let if finish, it should delete the temporary files and free the disk space.
I prefer to run the Disk Utility from the Tiger install disk when doing a Verify, Repair, or Erase Free Space on my boot disk, so I know I won't be interfering with anything running.
