Should I be concerned (disk utility)?

Probably just being paranoid, but this seems different than the list of things I usually get for disk utility. Anything I should be concerned about?

"/" symbol where my disk should be mounted in disk utility.

I have a "/" symbol where my disk should be mounted in disk utility. I was just wondering if this is normal. I feel like it used to be a bunch of numbers and letters (probably saying where my disk was mounted). I have been having a bunch of hardware and CPU issues and maybe this could be why?

Disk Utility Backup Question

Hello, I have the latest Mac OS X updates on my Macbook Pro. My question is concerning Disk Utility. I am trying to backup my "home" folder or my entire hard drive as I am worried about losing files if my hard drive fails. I try to create a disk image of my "home" folder and about 10 to 15 percent of the way through, an error comes up saying that "(name of my home folder) cannot be copied" or something to that extent. I am fairly new to Macs, and I'm just wondering what this error is and how can I get around it and be able to back up all my information using Disk Utility, so that I can put it on my external hard drive. Thanks in advance,
Todd

Hello,
If you are trying to make disk image of the hard drive, and creating the disk image on that same hard drive, then that could be your problem.
You cannot really make an exact copy of something that is constantly changing.
Since the act of creating the image is also modifying the source, you would end-up going in circles.
You need to create your image on something else (a different drive).
That may not work either if the drive is in use while you are trying to make your image.
So, you could try booting from your original Restore Disk that came with your computer. Then, use the disk utility on that restore DVD to make your disk image.
But, if you want to go the easy route, consider using a utility like Carbon Copy Cloner.
http://www.bombich.com/software/ccc.html
This program can also be used to create a disk image version of your drive. That method would work like what you are trying to do now.
But, it can also be used to create an exact clone of your main hard drive to an external or second hard drive.
This would be a bootable backup that can be used to put your entire system back exactly as it was at the time of the backup.
This means that if something happens, you can boot from your external drive, and resume normal work. Or, you can boot from the external drive and run the program again to restore your computer to match the backup.
This backup is an exact clone of your entire installation, so it is readable by another machine.
It works great, and I've never had a problem with it.
If a full backup is not what you want, you can customize your backup to grab just what you want.
But, I use the "Clone" feature.
This has the advantage of being able to restore quickly, and return back to the exact point you were at when you backed-up.
And, by being able to boot from the backup, you don't have to use another computer or re-install your OS before you can restore. Just boot from the backup and restore.
I actually have my external hard drive partitioned into two sections.
One partition is used just for holding my system backup. It is sized to be large enough to hold my entire OS X installation and everything I keep on my system.
The other partition is the remaining portion of the drive. I use that one to hold large files that I use less frequently.
This works great because I can just over-write my backup partition for each backup without worrying about my data files (since they are on a separate partition).
And, it makes things much easier to manage.
This backup is the most flexible backup method there is.
You can use it to:
* Boot if your original hard drive were to fail completely
* Boot if your original hard drive's OS X installation were corrupted
* Restore your entire system to the exact state of the system at the time of backup. This means no re-installing and then restoring. Just boot and copy the drive back to your main drive. Nice, fast, and you're done.
* If you don't need to restore the entire drive, then just grab the files you need.
* It's readable by any Mac OS computer. No special software required to access it's files.
Another popular program is SuperDuper:
http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
This program has similar capabilities to the one I use. But, they charge for the full version.
But, if you want to use built-in tools, you can use the Disk Utility built-into Mac OS X. This article describes that and other methods:
http://homepage.mac.com/geerlingguy/macsupport/mac_help/pages/0016-backuposx.html
Also, keep in mind that in order to have a bootable backup, you need a FireWire drive or a computer that supports booting from a USB drive (only the new Intel Macs support booting from USB).
Naturally, if you do make a bootable backup copy, you'll want to make sure and test it before you count on it. So, you should boot the computer from the backup copy, and make sure that it all works as it should. That way you'll know it works when you need it.
To boot from an external drive or partition, turn on your computer, and press and keep holding the "Option" key until the selection menu appears.
A menu will appear, and in a few minutes you'll be able to choose the drive / partition you want to boot from and proceed from there.
I hope this helps.

MB pro shuts off after bootup chime, hd damaged/volumeheader related - disk utility can't repair - how do i recover/backup my files??

Hi guys,
My macbook pro late(dec) 2011, doesn't boot up anymore, it just turns off after the chime (whilst a gray bar is loading a bit and then the MB shuts off)...
This all happened after I upgraded to mavericks, safari and chrome were spontaneously shutting off, my macbook kept restarting (all after recommended app store updates), it had kernel panics etc. Last night after an update it just wouldn't boot up anymore! Pff.. what should i do?
Disk utility can't repair the damaged HD, it had something to do with volume headers..
I basically want to access my macbook's files and documents so that i can transfer them onto an external hd or back them up.. i just want my files afterwards i can reformat or whatever as long as i get the files and contents of my hd back..
Ive read of diskwarrior? Can i burn that on a dvd and insert it into my mac, then start my mac and then it allows me to drag and drop all the contents of my hd onto an external hd?
I need a genius to help me!! A step by step guide would really mean the world to me!!
Thanks in advance mysterious genius!!!

Step 4(a) open Disk Utility from Utilities on the menu bar, then proceed to highlight the external drive in the left sidebar as you say and choosing Partition from the row of buttons that appear top center in the main window of DU.
5(a) click Restore on the bar of buttons top center of the main DU window, then what you say. But use the name you have given the external drive in step 4, Mac OS X Extended (Journaled) is the way it has been formatted, use a name such as Backup or something obvious to you.
Step 7, On the menu bar, click File, then New Finder Window. In the left sidebar you will see Devices and the internal and external drives will be listed. Click the name of the external drive and then in the main part of the window you should see the contents of the external drive. You can click on the folder for Users, then your user name, and see what folders appear...make sure the folders such as Documents, Pictures and whatever else you use appear and have the content you expect to be there.
You want to be sure all the content has been copied over since the step of erasing the internal drive is going to permanently remove it from that drive.
And then after step 8, add step 9, from Utilities on the menu bar, choose Install Mac OS X, and if it asks where to install, choose the internal, Macintosh HD, as where to install.

Disk Utility Formatting to MS-DOS FAT Not Compaditible

Hi, I'm having problems with the new disk utility. In leopard I can format my sd cards to work with my wii but now after formatting both my sd cards neither of them work. Is there anyway to get them to work again? Or do I have to get a different disk utility? Any help would be great!

I am having a similar problem trying to create MS-DOS DVD data disks. I create a MS-DOS disk image with Disk Utility. Disk Utility shows it as a MS-DOS (FAT) 4.7GB. I burn it from Finder and in the Burn Dialog, it states that "This disk can be used on Macintosh and Windows" computers. I click okay, but he resulting DVD is in Mac OS Extended format.
Disk image files should be burned using Disk Utility, not Finder. Finder will create a DVD that is readable on both Mac and PC, but the DVD will contain the disk image file. A PC will not know how to open that to get at the data files inside.
A simpler way is to not use a disk image file, but just the Finder. Insert a blank DVD, wait for it to appear in the Finder sidebar, drag files to it, then click the Burn icon next to it. This will generate a hybrid DVD. A PC can read it even though a Mac will see it as Mac OS Extended format

Boot Camp and Disk Utility giving Error for my Hard Drive Volume

When trying to partition my Hard Drive with Boot Camp, I get an error message after a while saying that it can't be partitioned because there is an error in the volume and that I should check it in Disk Utility. After running Verify Disk, it had told me that the file count was wrong and that I should repair my Disk. I have leopard installed, but only had access to a Tiger Install Disc, so after booting to that and apparently repairing successfully, I booted back onto my Hard Drive and ran Disk Utility's Verify Disk again. Now it said that my Volume Header needs minor repair. I still get the same message in Boot Camp. Running Verify and Repair Disk from the Tiger Install Disc tells me that everything is alright and the Hard Drive doesn' need repairing. I read on an Apple article that verifying a disk that's booted can produce inaccurate results, and that it shouldn't be worried about, but I can't install Windows because of this! What should I do?

Hi,
you have to boot from the Leopard OSX DVD in order to repair the Leopard OSX volume on your harddisk.
Using Disk Utility from an OSX version that is prior to the one you want to repair can indeed cause more errors than before.
So, search for the Leopard DVD.

Disk Utility Will Not Stop or Shut Down

I'm having trouble with a Drobo drive set up as a Time Machine, but this is not I think a Drobo or Time Machine question. Drobo dashboard reports no problems but the drive will not mount. While trying to investigate that issue, I ran Disk Utility Disk Repair on the drive. It quickly reported "Checking file system" and then ""Volume repair complete."
Then it started "Updating boot support partitions for the volume as required." It has been doing that for about 4 hours. Roughly one hour into it I clicked on the button to cancel and stop the operation. The status line reported "Stopped by user," but the status bar on the bottom is still spinning those slanted stripes and if I try to exit Disk Utility is suggests that would be a bad idea because it has not stopped the operation.
Should I just tell Disk Utility to quit or might is actually stop on its own at some point. I know there is risk in doing so, but if it is never going to stop on its own I have to bite the bullet and take my chances. I do have other backups.

It definitely should not take 4 hours especially for updating the boot support partitions. I would suggest stopping it, I would think if the drive does have damage it would already be present considering how long it is taking, not from you stopping it.

Tiger Disk Utility The Best?

Is the "Disk Utility" found on the DVD Install of Mac OS X 10.4.11 Tiger, the "best" software for "repairing disk permissions?"

Only if you are running Tiger!
Permission repairs should be done in Disk Utility on your internal hard drive.
Repairs to the hard drive itself should be done via Disk Utility on your install DVD once you have booted up from that.

How to use disk utility regarding repairing disk prmission?

I am using OS V.10.4.11, and my installation DVD have 10.4.8 OS version.
After erase and install the 10.4.8, i updated the OS to 10.4.11.
After starting up in regular boot the disk permission shows- Permission differs System/library/user template should be drwx--- they are drwxr-xr-x.
After starting up from installation dvd-1, disk permission shows- permission differs system/library/user template should be drwxr-xr-x they are drwx---
I don't know which one is correct. And also confused about which one that i should use for disk maintainance. The one with start-up disk or that one with installtion disk? Please help me.

As Dave said, permissions should be repaired from Disk Utility in Applications>Utilities.
A permissions differ message isn't necessarily a problem; it's a notification more than anything else.
If you're worried, download and install the 10.4.11 combo update again, then run the repair permissions once more. If they remain unchanged, and you're not having any troubles, don't worry about it.

Disk utility with audio CD

I used disk utility to copy non-commercial audio CDs to dmg files. I expected the dmg files when opened to be recognized by the Finder as audio CDs, but they are not. Instead I get a removable disk image with aiff files.
If I want to convert these back to audio CDs, what is the best way to do it? Should I just have Disk Utility burn the dmg to a new disk or would it be better to mount the dmg file, drag the aiffs into Toast, and have Toast create/burn a new audio CD?
The CDs are live recordings of a high school marching band competition and I would like to try and keep the originally recorded quality.

The best way to make a copy of an audio CD is to make a disk image with Toast (since you have it), not Disk Utility.
Given that you have AIFF files and not the original disc, you can use Toast or iTunes to burn a copy. The quality of the tracks will be identical to the originals. One thing that will get lost is the length of time in the gap between tracks, since you have only saved the tracks themselves. You can also get the order of the tracks rearranged it you're not careful.
For the curious, audio CDs don't have files on them--the tracks are just streams of bytes. The Mac OS presents the tracks as AIFF files for your convenience, and that's what Disk Utility uses.

My White Macbook is stuck at the loading screen, and disk utility, safe mode doesn't work either. What should I do?

I went on vacation a few days ago and in El Salvador, they have this mobile broadband sticks. Well, I was using one until it gave me a network error. After that, it shut down my computer entirely. The first time it happened, I didn't think much of it. I took the battery out and put it back in for it could work. It happened another two times, and after the third time, my MacBook stays stuck at the loading screen, and it will take 5-10 minutes on that screen, before it shuts down, or it wouldn't turn on at all. I've tried booting into safe mode, but it appears to not boot into it. I've tried resetting the Pram, and using disk utility, but that still won't work. I don't know what else to do to make it boot into OS X Lion.
I'm an AP student, and the majority of my work is in that computer, and it is very important! What can I do? Not only that, but I enter school in a few weeks and I need the AP work by the time I enter.
What can I do? Can someone help?
Thanks

Reinstalling Lion Without the Installer
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

So, you can't Install OSX to the external?
Or you can't boot from it when you do?
You're not the only one wondering... I'm reminded of the Goose that laid the Golden Egg story.

About one month ago, my computer started getting very sluggish (ie, it would take forever to startup, would always freeze after sleep, etc.) I lived with it for about two weeks, since it would always run quickly after waiting ~30 minutes after starting/waking up. Eventually, this grew old. I browsed the internet and did multiple suggested fixes (reset PRAM, run Disk Utility, ran in Safe Boot Mode, etc.). Nothing seemed to work. I opted to zero out the harddrive and reinstall Mountain Lion after making a backup. That was about two weeks ago.
Everything worked fine, up until yesterday. Once again, things started getting slow. I decided to shut down my computer for the night and would check it in the morning. When I turned it on this morning, it wouldn't startup correctly. I could login, etc., but it was frozen and I couldn't open any applications without getting the spinning beach ball. I waited about an hour, but it was still slow/loading. I shut the computer down and booted it in Verbose Mode. I ran the various commands to check the conditions of my disk, but when I ran the "fsck -fy" command, I got an "I/O Error." I then tried rebooting my Mac, but it would get to the gray screen with the apple logo and the spinning wheel, and then the progress bar would appear. Before the progress bar did anything, it would shut itself down.
I then started the computer up and directly went to OS X Utilities. I went into Disk Utility and tried to check permissions and repair the disk. Only this time, Macintosh HD was grayed out and seemed to be unmounted. I couldn't get it to mount. I went into the Apple Store to have them run their own diagnostics. However, the apple store employee was unable to get the test working, so that was basically a bust. At this point, the computer still didn't turn on.
I got home and, just for kicks, held the "N" key while booting up my computer. For whatever reason, my computer started up (though it took a long time and there was a progress bar). Now, I made another backup of my disk and am wondering what to do. I ran Disk Utility again to repair my disk, but it says that Macintosh HD is not able to be repaired. When I checked permissions, there were tons of Input/Output Errors. Based on my research, it would appear that I have two solutions.
I can either purchase DiskWarrior and use that to try and solve my problem, or I could just get a new hard drive (and I would upgrade to a SSD or SSHD). DW is about $50 if I just download it, and the hard drive would cost me $150 or so. Since I don't know exactly what is wrong with the disk, I don't know if DW would be able to fix it. That being said, if the hard drive isn't the problem, there would be no reason for me to purchase a new one. I guess I would just like some advice, as to what you would do. I apologize for the long post.
TL;DR: Disk Utility can't repair Macintosh HD. Should I get DiskWarrior or a new harddrive?
Thanks in advanced!

Most importantly, youve already backed up all the data. All else is cake.
A new HD would cost you only $20 more than disk warrior,....theres no reason to repair a worthless crippled HD, .....new HD 1TB is $70.
Once you back up all the data on a failing HD, further diagnosis has no meaning,....not anymore.
Grab a 1TB or 750GB Toshiba/Hitachi (both used by Apple inside their Macbook Pro nonRetina,...both are made by Hitachi) 5400RPM SATA HD.
Forget the repair,.......repair only serves to bring a HD to a point of BACKUP.....since youve already done that, its now just wall art or trashbin fodder.
These are the same HD used by Apple in their Macbooks

In the future ALWAYS remember to have 2 backups for everything. 2 backups is 1, and 1 is none.
That way when something crashes (and they all do).....its no worries.

How long should I let Safe Mode startup run? I keep getting the "disk0s2 i/o error" message and I'm just not sure when to give up and try a different method. I already ran disk utility in Recovery Mode and it said there were no repairs needed.

You have limited opportunity to attempt to create a backup of your created files.
That is what the SafeBoot or safemode appears to allow you -- at the moment.
Since the hard disk drive exhibits signs of failure or other major issues, plan
on a replacement in the near future. You may be able to get the computer to
start up in a regular full OS X (not safe mode) but consider its hours are limited.
An externally enclosed hard disk drive (with own power supply, not relying on
Mac ports to run it) is a good basic means of which to use a disk utility to make
a copy or a Clone of the current OS X. This may help retrieve an archive that
could be used along with a Time Machine backup, to restore your Mac once you
get a new hard drive installed inside.
Good luck & happy computing!

Should I be concerned (disk utility)?
