In disk utility, after an erase of my HD, it still shows used file space. How do I completely erase the HD?

My computer wouldn't boot past the white screen and after trying a few things, I was able to find the original installation CD, hold C while turning the computer on and get into disk utility. I tried running a repair on the HD and it said the disk could not be repaired. I tried restoring from a backup, but about 20 min into the installation, I got a message saying the installation couldn't be completed.
I decided to try and just completely erase the HD from disk utility then try the installation again. However, after I try erasing the HD, it still shows there is used space, six folders and two files.
The HD I'm trying to erase looks like it's a partition under something called "250.06 GB toshiba mk2555gsxf media". Should I try erasing there? I'm not super tech savvy and I'm nervous to do more damage.

From what you wrote, your disk may be altered or dying. Diskutility shall give you full report after testing disk integrity, but it seems you'll have to change your hdd pretty soon.
Anyway, what you see as "250.06GB ... Media" is your physical hdd. Macintosh HD or any name your hdd have under MacOS is just a partition on this hdd. But MacOS needs others hidden partitions for EFI and recovery, for instance, which take some space even if you don't see it.
If you really want an install from scratch, you may click on the Media line displaying your hdd, go to erase tab and write another partition table. Afterward, create a single partition and installa MacOS. If your disk is dammaged, it won't repair it.

Warnings when running disk utility after downloads, etc.

I use Mc Janitor nightly to clear some of the 'stuff" that accumulates with files, etc. but run Disk Utility after downloads and such about once a month. I have done this since 2003 when I had my first e-mac. Only recently have "warnings " appear on the list of repair or varify disk...that says certain items can not be repaired. The techs at the Apple store said to just ignore them, which I have been doing. But the last download, which was a rather large new Security download, came up with something new, both on my computer and my husband's lap top when he downloaded it. These are letters that appear and say ACL found but not expected on Applications/Utilities, on "Applications" and on "Library."
We are just curious about what ACL is (or are) and what it means to have them in our systems.
It does say that the disk is verified when I run that. Everything seems to be working normally.

"Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility." Trying to format my iomega external HD for use with Mac

Hi. Trying to connect iomega ext. HD. i have to reformat for Mac. When i plug in & go to Disk Utility,the external shows up and i'm supposed to click "partition". When i do, a box comes up saying ""Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility." I quit and relaunched, same results. After googling my question, i came up with this:
"Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility."
(Quitting and reopening Disk Utility does not help.)
The following also appears in Console log:
*** malloc[419]: Deallocation of a pointer not malloced: 0x290a410; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug : for architecture i386 object: ./Applications/iTunes.app/Contents/MacOS/iTunes malformed object (unknown flavor for flavor number 0 in LC_UNIXTHREAD command 27 can't byte swap it)
Workaround
Quit Disk Utility.
From the Finder's Go menu, choose Go to Folder....
Type the following, then click OK: /Library/Receipts
Temporarily remove these iTunes receipts from /Library/Receipts (sort the folder alphabetically as a list):
iTunes.pkg
iTunes4.pkg
You can put them on the desktop, for example. Do not remove iTunesX.pkg or iTunes Phone Driver.pkg.
Open Disk Utility and repair disk permissions again.
Quit Disk Utility.
Put the removed iTunes receipts back in /Library/Receipts.
Note: This issue does not affect Disk Utility's verify or repair disk features.
All seemed good, for a moment, until, upon going back to Disk Utility after removing itunes4.pkg and putting on desktop (i did not have itunes.pkg to remove) the same thing was happening. When i highlite my iomega ext. on left of page, disk perrmissions is grayed and does not allow me to click on it. Same problem from the start. Can somebody please help me out here? That would soooo awesome. Thanx!

i'm just scared i will do something wrong on my own and lose my data.
You shouldn't be scared of that, because you should already have backups. If you don't have backups, then backing up is the first priority.
Insert the Snow Leopard DVD and restart. When you hear the chime, hold down the C key and keep holding it until the Apple logo appears on the display. You should now see the language selection screen. Select your language, then choose Utilities > Disk Utility from the menu bar. In the Disk Utility window, select the external drive (not the internal). The drive may already have a data partition, in which case there will be another icon below the drive icon. Choose the drive icon, then select the Partition tab. Create a single partition with the default options (GUID partition table, Mac OS X Extended Journaled).
When the partitioning is done, select the startup volume on your internal drive in the DU window. Select the Restore tab. Drag the icon of the startup volume to the "Source" field. Then drag the icon of the newly-created volume on the external drive to the "Destination" field. Make sure you have this right. Then click the Restore button, and the data on your startup volume will be copied to the external drive.

I am trying to reset my 4s iphone to the original settings and erase all my content. It is asking for a passcode which i have not used before. How/where do I get the passcode?

It needs the restrictions passcode. You or someone with physical access to the phone had to set it. It can not set itself.

How do you completely erase Apple Server as if it never existed?

How do you completely erase Apple Server as if it never existed? I keep having issues with my Apple server so I want to erase it as if it never existed. I have tried doing "sudo rm /var/db/.ServerSetupDone" but it still saves settings from before. I just want it to install as if it never has been set up before on my iMac.
Thank You

Move the Server application to the Trash. Delete the following items (some may not exist):

Hard Drive Upgrade - Incorrect Capacity Shown In Disk Utility After Installation

I have an older model Macbook Version 2.1 that had an 80GB hard drive installed. I have just installed a Western Digital Scorpio Black 500GB internal hard drive upgrade and successfully cloned my data over using Carbon Copy Cloner. The problem I have encountered is that only 98.1GB of capacity is shown in Disk Utility for the new hard drive. After starting the computer using my bootable copy via an external USB drive, I formatted the newly installed 500GB drive with the appropriate Apple formatting (e.g. GUID and Mac OS Extended Journaled) but it only shows 98.1GB of space available on the new drive. I was able to successfully clone the information from my bootable back-up of the old drive to the new drive but I just don't have the full 500GB capacity available to me.
What should I do? Is this a problem with the new hard drive or is there something I need to change on my Macbook to "see" the whole capacity of my new drive?
Thanks for your advice,
Dave

Hi Andrew,
When I formatted the new drive did it with 1 partition and it displays a TOTAL of 98.1GB free space (both in Disk Utility and About This Drive). As far as I can tell, the Macbook is treating the new WD drive as if it is only a 98.1GB drive rather than the 500GB drive that it is.
Thoughts?
Dave

Disk Utility after trying to partition

Okay, so I've read a lot of discussions about partitioning, but none of them seem to match my situation.
After I run Bootcamp, I get the error: "The disk cannot be partitioned because some files cannot be moved. Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
Then, when I go into Disk Utility - Partition, everything is shaded such that I can't change it [but it says that is in Mac OS Extended (Journaled)] and then another portion is shaded.
I have backed-up my data, but when it refers to 'disk' I'm a little bit confused. Does this mean HD? Still new to Mac.
Thanks,
Cristi
Oh yea, I noticed there was a SP-2 for windows on this site. Is this so that it can be installed with the disc (that doesn't have SP-2)? If not, can someone please offer a cheap alternative to this? I have a ton of XP disc with SP-1

I don't know if this will solve your answer caz I do not understand the question
and yes disc mean HD that's first, second to install BootCamp your HD must be a single partition ( You must only have one partition ) if not formate the HD and install the BOOTCAMP while it is single formated.
hope it helps

Disk Utility: after creating the .DMG (compressed image) When "scan image for restore" finishes it displays "unable to scan (internal error)". Since the process was scanning for about 1 hr is this a fake warning?

External 500GB drive is partitioned with 400GB for Mac OS extended (journalling) and 2nd partition formatted today as "ExFAT".
Yesterday I tried to create a disk image of my HD to no avail - this was compressed on a FAT partition. I got a warning after running the <scan image for restore> saying "unable to scan (internal error)"
I rang Apple support who suggested formatting a partition as MAC OS extended (journalling) and choose to save the image as "read/write'. The image process stopped writing at about 200GB and then the file size jumped to 499GB (ie the size of the HD). But the process did nothing for about an hour so I foce quit disk utility (as suggested by apple support)
My current attempt was to format the external drive again; this time with a 400GB Mac OS extended (journal) format; plus a 100GB ExFAT format partition. The new image was created after about 2.5hrs with a compressed size of 149GB. However, after running the "scan image for restore" facility I got the warning message "unable to scan filename " (internal error). The process was scanning the image file according to the progress bar - this took about hour - thus the warning is a puzzle.
If anyone can say more about this error I would really appreciate knowing tips for using disk utility. The screen grab is below.
"unable to scan filename " (internal error)
thanks

Thanks for a quick reply <baltwo>. You’ve answered that it is not a fake message!
fyi: I thought that I would use my external Buffalo for two purposes; namely the smaller ExFAT partition for copying stuff to my win7 netbook. The larger partition was to be used as my imac image of SL. So this was my first attempt at using disk utility - the idea being to hold an image backup at another location. Plus I now have the Lion thumbdrive ready to upgrade from SL and so being cautious wanted to have a SL image backup
Anyway I followed the apple instructions using my mac 10.6.3 install DVD but it would appear from other discussions that <unable to scan (internal error)> is not unique to me.
I’ll get back to apple telephone support for further advice.
I would though be grateful for an “idiots’ guide to making an image backup of my internal HD that runs SL 10.6.8
eg should I have just one partition on the external USB drive? format it as Mac OS extended? create the image as compressed or read/write? Basically I’ll do whatever will work!!
thanks again

Cannot burn encrypted disk w/disk utility after Yosemite upgrade

I upgraded to Yosemite and now I cannot create an encrypted disk with disk utility. I have a disk loaded with a project I recently completed with Final Cut X and I need to make an encrypted .cdr file for the purposes of making write protected copies for my client. I have always been able to do this by selecting the volume in Disk Utility, clicking New Image, and selecting DVD/CD master for the image format and then my encryption level (usually 128-bit) ALWAYS WORKS but not since upgrading to Yosemite. Now every time (after restarts, etc.) I'm getting first a dialogue box telling me it's starting to create the .cdr then quickly an error box that says: Unable to create "<disk name>.cdr" (Inappropriate ioctl for device) HELP!!! Need to get these disks burned and out to clients ASAP!!!

Are you trying to save the file to the desktop? I read elsewhere that Yosemite doesn't like that permissions wise. I was able to successfully create a .cdr by changing the file location to Documents.

I recently downloaded is x mountain lion and while it finished it erased all my data, some of which I need. When using disk utility I found my old data but it says corrupted. I can't repair and while restoring the error code 32 Broken Pipe appears. Help?

My data I need is on my computer but it needs to be repaired but can't and when I try to restore it/back it up it ends abruptly with error code 32 broken pipe.
It was damaged while installing os x mountain lion and I found my data on disk repair (utility)

Sounds like your hard drive is badly corrupted, likely due to problems that were already there when you started trying to install Mountain Lion. The problem is, if you don't have any backups already, you may not be able to recover all your data from this state. Do you have backups of that data already?
If not, I assume when you say that "it needs to be repaired but can't," you mean that Disk Utility tells you there is a problem with the disk, but that it is unable to repair it? If so, you can try repairing the drive using DiskWarrior, which can repair problems that Disk Utility cannot. That may give you access to your data again, but may not.
Also, it's important to understand that if your data is not backed up, everything you do with the computer runs the risk of overwriting or corrupting that data. You may want to go straight to trying to recover your data. See Recovering deleted files.
Regarding the error code, if you're trying to back up the drive using Disk Utility's Restore tab, note that that is often not successful when the drive you're trying to back up is corrupt.
Once the situation is resolved - either because you have backups, are able to recover your data files or are forced to accept that they are gone permanently - you will need to erase the hard drive and reinstall the system and all your apps from scratch.

Is it normal for an external HD to blink its light and still be visible in Disk Utility, after it's been Ejected?

After Eject, the drive disappears from Finder, stops spinning and its light starts a slow blinking pattern, but in Disk Utility the volume appears greyed-out and unmounted while the HD is still visible (not greyed-out). If you try to re-eject it from there nothing happens... Disconnecting the HD's USB cable after a normal Eject (from the Finder), does not prompt any type of "incorrect ejection of volume" messages.
Other drives that I tried, only differ in the activity of their light post-ejection - some stay still, others blink.
Just for reference, when I eject a USB Pendrive from Finder, it disappears completely and stops blinking.
Is this normal OS X behavior?

This is probably normal. Some drives blink when being written to/read from, while others blink unless read/write is occuring.
but in Disk Utility the volume appears greyed-out and unmounted while the HD is still visible (not greyed-out). If you try to re-eject it from there nothing happens...
If this is just for a few seconds, that's normal. If it's permanent, it's not.

Normal/good.

See above.

Normal; a flash drive has no source of power and could not possibly keep blinking.

Did anyone else lose the ability to see recovery drive in Disk Utility after 107.1?

After I updated to Lion 10.7.1 I can no longer see my Recovery Drive in Disk Utility. Did 10.7.1 take that away ?
Just cusious.

Disk Utility does not display the recovery partition in 10.7.1. I don't remember seeing it in 10.7.0 either.
I do remember seeing it. I guess they removed its visability.

Disk Utility after upgrading to Lion

I couldn't get disk utility app to work from the Finder. I finally figured out to go to the "About This Mac" menu, upper left apple emblem, then clicked More Info.. then Storage then Disk Utility at the bottom right. Then I was able to set up my back up external HD for Timemachine. Took HOURS to figure this out. Hope this saves someone a lot of time.
texastreeman

Mine doesn't look like that. I have a MacBook laptop. It has a "Dock" and in that Dock is "Finder". The old "Disk Utility" is in "Finder" and doesn't work. It's also in "Launchpad" and it also doesn't work. I can't find where my screenshots are going, for some unknown reason, or I'ld show you. The screenshots used to go to my desktop. Anyway the new "Disk Utility" is now in the "Apple" menu at the top of my "Safari" browser window on the left and looks like an apple. I clicked "About This Mac" then "More Info..." Then I chose "Storage" from the 4 options. Then "Disk Utilities" on the bottom right. Okay I figured the screen shots out. Much of the new OS different. See on the right is the "Dock" and I've magnafied the "Finder" by mousing over it. It has the smiley face and under it is "Launch Pad". Top Left is the Apple where the new and only working "Utlity Disk" is now located.

Which Disk for Disk Utility after Leopard upgrade?

Greetings,
If I need to run Disk Utility from the DVD, which disk should I use? The original disk that came with my iMac when I purchased it, or the Leopard install disk that I upgraded to a little over a month ago?
Thanks in advance - Scrags

If the earlier Disk Utility didn't try to "repair" anything. then the Leopard Disk Utility should still work.
If the older Disk Utility tried to repair a Time Machine volume, it might remove folder hard links. The Leopard Disk Utility would have no way of fixing that.

In disk utility, after an erase of my HD, it still shows used file space. How do I completely erase the HD?
