OS X V10.7 Lion :: Can Use Disk Utility On 10.6
Jun 11, 2012
Last year I bought a new 17" MacBook Pro, that came with Snow Leopard 10.6. I think it was just before I got my new MBP that I got an invitation to try the Developer Preview of 10.7 and offer feed back. Well, after using my new MBP for a couple days and backing up everything with Time Machine to an external hard drive I downloaded and installed 10.7 Preview.Â
After a few hours of using it I was not happy with it at all (long story short, several things indicated to me this was a pretty early version of 10.7 and I didn't want to use it on this machine). So I erased the drive and restored everything from my Time Machine backup. That must have been around a year ago or so.Â
Now I want to add a 100 GB partition to this hard drive so I can install Lion on the new partition to try it again. But my version of Disk Utility (11.5.2 (298.4)) won't let me add a partition. It looks like it is going to add a partition but then I get "New partition requires a newer version of OS X".Â
I think when I installed the Preview of Lion it did something to my drive/partion for some of the new features it supports. But, if I can get a copy of the Disk Utility that comes with 10.7 would that run under 10.6? And let me add a partition?Â

I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!Â
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.Â
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state!  Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.

I have run the Disk Utility verify function against my system partition. It tells me there are minor issues that need fixing up and I should run the repair disk function, by booting using Command-R and using the Disk Utility to repair the drive.Problem is, when I boot using Command-R and select Disk Utility the partition is shown greyed out and the Verify and Repair options do not work.I think this could be because the partition is encrypted. The utility does not offer me the chance to unlock the partition with my passphrase.How can I repair the filesystem errors on this partition?

Fortunately I got a time machine backup. And its restoring the drive while in Lion recovery mode. Here's what happened... I dont have a router a my place at the moment and so my two phones (iphone 4 and htc android) connect to my internet using my MBP's wifi via internet sharig. For some reason they were not able to get an IP from the mbp. After doing some wifi swtich toggles and forgettig & rejoining the network, i decided to reboot all my devices. I shut down my modem, phones and restarted my mbp. On reboot, after the chime, it showed an unsusal 'progress bar' under the apple logo. The bar progressed to about 10% and then the mbp just powered off. This happened several times even after PRAM and SMC reset. Â
So now i booted with cmd+r pressed and in recovery mode ran a 'verify disk'. It said the verification stopped and that i should repair the disk. When i tried to do that it said the disk cannot be repaird and that i should back up as many files as possible and attempt to format the disk and restore it with time machine. It is precisely what im doing at the moment. Â
1. Mbp wont sleep even when internet sharing is off
2. Mbp wont lit the onboard display upon opening it in clamshell mode until i removed the 3.5mm audio cable of my speakers from the audio out port!Â

I'm running Mac OS X (10.7.3). I need to make an image of my boot disk, before I install a larger HDD in my MBP. My boot disk is greyed out in DU:I had already dragged my com.apple.DiskUtility.plist file to a separate disk (I actually found two - both dragged away), and that disk was selected in DU All I want is to create an image to restore to the larger HDD. I have a 4TB Raid drive on which I have created previous images; now I can't.Â

I just got my computer yesterday and when running the "repair disk" function, I already get an error! Since I used migration assistant to move everything off my old mac to my new mac, I'm not interested in reinstalling the whole OS and transffering all my files again. This is a new computer, and shouldn't have this problem this early. I also get the same result when starting up in the recovery partition. How do I resolve this?

I was going to run Disk Permissions and when I opened it up, there is a decrypted file.dmg showing. Here is it's path:/var/folders/2d/vmlqi1 d0gzcs7mxi nnl 1w0000gn/T /decryptedFile.dmg...I opened it and saw that it has something to do with installing Adobe Flash Player. I remember downloading and installing it a couple of days ago. I've adonw this previously, but never had the disk image show up in Disk Utility before. How can I get rid of it? It seems to be in a folder calledl "T" that I can't find anywhere.

I'm trying to restore the partitioning of my late 2011 Air drive, after messing it up while trying to dual boot OS X and Linux. The goal is to get rid of the superfluous partitions and resize the OS X one so I can use the whole drive again. Data loss is not an issue. According to Disk Utility the partitioning looks like this:Â
EFI
Macintosh HD
Recovery HD
06
[code]....

I installed Ubuntu on my Macbook but it didn't really work for me so I deleted it. I used Disk Utility to delete the Ubuntu partition, but when I want to delete a Linux-swap partition I made while installing Ubuntu nothing happens. I press the minus button and it will delete it. But after deleting it just stays there, and I can't change the partition in any way. How can I delete the partition?

I don't know if this is a problem or not, but recently on my 15" MBP using Mac OS X Lion 10.7.3, clicking on a .dmg file automatically opens Disk Utility. Which is weird, since before this situation happens, opening a .dmg file will not automatically open Disk Utility. I have a screen shot below opening the .dmg file for Firefox installer for Mac OS X. Shouldn't it actually be like this when clicking on a .dmg file? Is there a problem with my MBP or my Mac OS X Lion?

I cloned my existing SSD (From 96GB to 256GB), everything seems to be working fine.Using 256GB, i am able to boot up and it is working okay. Now I am trying to upgrade to Lion, but it says "This disk cannot be used to start up your computer".Anyone know what could be the reason.Do I have to unplug the 96GB SSD?I tried by ejecting, but still not working.

I just reinstalled Lion from a fresh harddrive. I did not use the migration asistance to pull files over to the new drive, I selested files and dragged them over, So not to fill the drive with things I dont need....Â
So I "Get info" on the main harddrive it shows Which is crazy! Then I use Disk Invintory and it shows: Â Â
and Disk Untility shows: Â Â
Why the difference? Simple question and How do I free up space? I'm also trying to back up using time capsule*

I am trying to make a redundant backup image of my harddrive using something OTHER than Time Machine. I booted to recovery because you image from a disk you are booted from. The restore took 2 hours, and indicated the entire time in disk utility that it was restoring "Mac HD" to a similarly sized partition on my external hard drive. When it was done, the external had a copy of my recovery drive on it. That's crazy talk.

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.Â
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.Â
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 have an external WD drive in a self-enclosed case, both purchased from OWC, used for my Time Machine backups. The disk and backups have been running just fine since I began using this disk over a year ago.Â
When I plugged in my disk yesterday (USB), it didn't mount. I ran Disk Utility on my 'Time Machine' partition, starting with verify disk. It reported that it needed to be repaired. When I run repair, it runs for several minutes and I see information of what is being done -- incorrect block count for file shutdown_time, incorrect block count for file permStore, etc -- but I always ends with "Disk Utility can't repair this disk" and that it needs to be reformatted.Â
I've run Repair Disk multiple times, all with the same answer so it seems running it again won't change the problem. Reformatting and starting fresh with Time Machine seems to be the only course of actionÂ
What specific issues should I be aware of as I reformat my Time Machine drive/app partition?

I had an external hard drive that was formatted to NTFS that was used on my PC but I want to switch it over to mac now. I erased the partition on Windows, then plugged it into my mac but it's stuck at 'preparing to partition the disk'. What should I do, it's been stuck for ages!!

Bought a used 4 TB Seagate drive, formatted it , checked the speed 150 MB/s read/write and made a partition. Apparently it worked perfect.Â
However after this first partition the drive is behaving erratically. I can not modify partitions anymore nor delete them. Repair disk is not finding any problem either from the system or from the recovery partition.Â
I am starting to believe the disk is damaged. Beside the partition problem the disk is behaving fine.

In fact I'm getting a grey screen when I just try to restart. Have run Disk Utility (which always finds Permissions errors - even though it appears to make repairs. Also, after erasing my hard disk and recovering my user data from Time Capsule). When I restart I don't get beyond a grey screen (with moving cursor). I can't install the update as obviously I need to restart in order to start the install process.

I have the "show detail" box checked but Disk Utility is not showing detail. It goes through verify and repair, says it is finished, but shows no files. I have never had No files need repair. My computer has been slow and erratic and usually running Disk Utility works, but not now.

After backing up my data and then swiping my hard drive using Disk Utility, my OS seems to have been uninstalled as well. Is there a way to recover the deleted information and go back to the last working configuration? I'm on a MBP IC2D 2.16 w/ Lion.

Have just downloaded Adobe Flash and went to do permissions where I found the file "install_ flash_ player_ osx." and also the icon with "Flash Player" directly underneath.These are listed under the list of drives to select on left side of pane. Is this normal? Do I need to do permissions? On HD?

i have this strange issue that occured just out of nowhere without me (knowingly) having contributed anything to it.yesterday i launched my iMac and my external firewire drive wasn't showing up in neither the finder nor on the desktop. i instantly thought about a hard drive crash, but soon tried other things to evaluate (or not) my guess.Â
for instance, i unplugged the drive waited a few minutes before i plugged it in again. since this iomega drive is also equipped with a regular usb port i also switched cables and tried connecting it via the iMac usb sockets as well as via an usb hub without any luck. the drive still won't show up. so i launched the Disk Utility, to see if the drive needs some checking/repairing, but to my surprise it wasn't showing in Disk Utility either.Â
thus far i only considered this to be an issue with only this particular external drive, but when i eventually switched on a 2nd external drive (this time an usb drive i use for Time Machine) that drive also refused to show up in either the Finder or the Disk Utility app.Â
curious as i was, i then fired up a 3rd and 4th external drive and now had all 4 drives running at the same time. none of which were showing up, just as if they weren't even connected with the iMac.Â
this strikes me as more than odd. i've heard about hard drive failures and crashes. they just occur over time. maybe and under some very strange coincidences it is possible that two external hard drives quit their jobs at the very same time, but seriously .... 4 of them?? i hardly think so.Â
well, maybe it's the iMac's usb/firewire controller that's causing the trouble, i thought. but then again, my other connected devices (iPhone, iPad, Printer, Scanner, eyeTV) are functioning and get detected just fine as far as i can tell.Â
i have no idea what's going on. i dismiss the idea of 4 external drives having crashed all at the same time just as much as i don't think that the iMac's usb/firewire controller has got any issues. re-formatting any of the 4 drives is out of the question and even if i'd consider such desperate measures, the Disk Utility wouldn't let me re-format anything anyhow, because the drives aren't listed there. i wish i could just use my Time Machine to resolve the issue but, as i mentioned earlier, i can't access the Time Machine because it also won't show up.Â

After I erase the hard disk it shows 74.5gb free, almost. It says there is 42.3mb of space being used by 2 files which I understand are used for read write or partitioning or whatever.
When I then leave disk utility and go to the actual installer, the destination disk (untitled - 74.5gb) shows only 73.9gb free space. What is taking up an additional 500mb of space on the hard drive?
Apple support told me that somehow the disk has been altered and I lost space on the disk or I am now using a seperate partition that isn't showing up. Disk utility shows only one partition with 74.5gb free space. He told me I can find information about how to 'merge' the disk on the apple support section under troubleshooting articles for disk utility. I have been unable to locate this information.

I get this question mark along with a folder when starting up. I tried holding down the option key when turning on the power and then I get an internet recovery along with a globe. I click on the arrow below it and it takes maybe 15 minutes to start up. Then i get this disk utilities screen. I'm now unable to do anything. When going into disk utility, disk 0 shows with Mac OS X base system underneath it. All the clickable buttons are faded out. Is there something wrong with the hardrive? and where could i get this fixed? There isn't a warranty on it.
