MacBook Pro :: Disk Utility Does Not Allow HDD To Be Erased
Feb 17, 2012
I am attempting to erase my Hard Drive so I can start from scratch and the disk utility tool does not allow me to erase. The hard drive is grayed out. I want to reimage my computer, but I cannot use the CD that came with it because it came with Snow Leopard, and I am running on Lion.
I just bought a new WD hard disk and backed up all my data to it (80 GB). I then performed a clean install on my Macintosh HD.
Before I restored my data to the internal drive, I thought it would be a good idea to copy my fresh installation to a new partition on the external disk.
So I booted up disk utility to check if partitioning would affect my data. Using the partition tool, I clicked the plus sign (without applying changes). Disk utility said that if I add a partition, it would simply add a new volume and that the previous volume would not be erased. I clicked apply, and now there is nothing left of my data in the original partition.
Can I get it back? Undo the partition, or file recovery?
I have my imac apart right now and replaced the internal HD as it was not working. I assume the problem is the new one is not formatted with OSX, so from the INSTALL CD I opened the disk utility and see only one drive called "MEDIA".? Or is that just part of the install dvd that looks like a HD? In the system it shows as not formatted, 0 bytes. When selected in Partition it says :
"This voume is the startup volume and cannot be erased. Size 7.1 GB The disk is not writable and cannot be partitioned"
So i guess thats not my new HD I am seeing? Other than that there is only the two OSX install CD icons.
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.
Macbook Pro running on OSX Mavericks is having problems.
Today I turned my Mac on, and it started up with a loading wheel and a loading bar. When the loading bar finished, the Mac turned itself off. I tried many times, same happened every time. I then went into OSX Recovery, started repairing Macintosh HD, but the error message saying "Disk Utility can't repair Macintosh HD" came up and now I don't now what to do.
Is there any way I can back up my files in this situation? Is there any way I can repair the disk without having to erase all data and reinstalling OSX? Or do I really need to bring it to a Apple Store for repair?
I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive” Checking file system Volume repair complete. Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?
I have a Macbook PRO late 2011 running OS X Mavericks.
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.
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.
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!
I am trying to repair my mac. But in disk utility, the hard disk is not visible to proceed. Its showing disk0 -> volume with only 1.79GB. and all the options are disabled. The capacity of my mac book pro was 500GB.
I am having a problem with my disk space as I recently, by mistake, used the erase free disk space feature in Disk Utility, "loosing" in the process around 30 gb. Is there a way to reverse this process and reclaim the lost free disk space (without having to backup all the data and restore the entire system?
I have just erased all of my architecture honours year et all off my computer.
I have two laptops at the moment as one is faulty. Needed to free up some data from time machine as it was nearly full before back up my computer to transfer to the new one. This is going to sound like madness but i deleted all of the time machine backups, because I also have old backups for a previous laptop and there is only enough room for both. Then to free up even more space i downloaded Back-in-Time to remove some rubbish from the old mac back ups, found a file I had been looking for and tried to restore that to the desktop. HOwever i clicked the wrong button and it started restoring my whole computer. It wiped my desktop and everything. I managed to stop it after only 66 KB were written. I have removed the time capsule. Is there any way to get my stuff back ? I really need it because it has all the work from my honours year, and i have deleted all back ups...
I just attempted to transfer my files from my old powerbook G4 15" to my iMac 20" using Target disk mode. First I tried to use a firewire cable but it didn't work, I think I was using a 400-400 instead of a 800-400. So I used the option to connect to two computers over a shared internet connection using a password. I thought It would automatically transfer my photos and other files but it just transferred these weird extensions for applications and I don't recognize any of it. To make it worse, I tried to open photoshop on my iMac and now its asking for a password! None of the photoshop series would open, it's asking for a serial number. I had photoshop installed before and the guy doesn't live in my state who installed it for me and I don't have any of the original disks. I know Dell does system restore but Macs work differently. I wish I could undo this whole mess, I need photoshop!!
I dont have the original OS disk either, ughh I should have just splurged on a portable hard drive.
I just saw that the amount of memory left on my HD just dropped around 60GB, so I used the "Verify Disk" option on Disk Utility, and the output was: Verifying volume “Macintosh HD”Performing live verification.Checking Journaled HFS Plus volume.Checking extents overflow file.Checking catalog file.Checking multi-linked files.Checking catalog hierarchy.Checking extended attributes file.Checking volume bitmap.Checking volume information.Volume header needs minor repairThe volume Macintosh HD was found corrupt and needs to be repaired.Error: This disk needs to be repaired. Start up your computer with another disk(such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
I don't have the disk right now, so is there some other way I can repair it, get another install disk, or anything else? I've been thinking of booting up with a Linux livecd, but can it access the HFS+ filesystem?
My Macbook crashed so I tried everything to restart it. what finally worked is opening it from the install disk. I performed a "repair disk", and after saying "invalid node structure" and "invalid record count", it says it cannot repair the disk. I don't know what step to take next. How do I see if time machine has backed my files up? Do I need to erase the HD and reinstall?
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 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!
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.
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.
Running Diks Util on my iMac 10.6.2. i am given this warning. ========= Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired.
Is it something I should heed and what to do in that case?
I had windows vista installed but suddenly the audio decided to become faulty, after spending a day trying to fix it i realized I have a windows 7 install disc so i might as well just replace vista with windows 7. I didnt take care of vista or ever register it so it became quite a task to upgrade so i just deleted the partition and went to create a new one and just do a full install of windows 7.
I made the partition but the wrong format, so i removed it through boot camp assistant and created another, except now it keeps giving me the "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" Now, I'd love to do this, except I have no idea what I'm doing and WHY this error has occured. After becoming frustrated I switched from my imac to my macbook pro and received the same error when trying to create a partition. So any help on exactly what I need to do would be a HUGE help. I only use windows for music production (I know, seems backwards, but I use Sony Acid and FL Studio so I'm stuck with Windows)
I'm trying to repair my hard drive. I restarted from the OS X Mac Mini install CD (holding down the letter C when I heard the chime), opened Disk Utility from the Utilities folder, selected my hard drive image, but the "verify disk" and "repair disk" options are grayed out. I'm at a loss as to how to proceed.
I have 43GB available on a 120GB drive on my MacBook base model and I'm trying to partition via BootCamp.I'm trying to allocate 32GB to the Windows partition but I keep getting the following error message: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.Now I've backed up my disk and launched disk utility, and try to follow above directions here but the Mac OS Extended (Journaled) area is grayed out and when I click apply after highlighting the MacBook are (in blue), it errors out and says the disk is out of space.
One of my drives is showing issues that Disk Utility isn't catching or can't find. I've heard about Diskwarrior, iDefrag, Drive Genius, etc... but which one is the most comprehensive, is there a "best of breed" disk app out there or one that does more than the others?
Running Disk Utility's Repair Disk function from DVD, how long should this take to complete with a 1 TB drive? It's been nearly 24 hours so far. I booted the computer from the DVD, and after verifying the disk was told the disk needed repair.
I am having problems with my Mac running slow. I had a friend guide me to run a "repair disk permission".I did that but I am not sure if I am to click clear history.Also should I do anything else to help my Mac run better?
I ran installer then went to disk utility and pushed disk repair. it ran and indicated in green that no repairs were necessary. i then went to startup disk and only the Diks and network startup showed up but no hard drive. i also open computer to make sure was not wet muddy due to leak in cooling system but all was dry
I am having an issue Partitioning my Internal HDD because some files cannot be moved it was able to Partition a while back when Installed Vista but I deleted that Partition as I needed a bigger one for Windows 7 Beta It says I need to "Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume." does that mean I have to reformat my entire HDD? as I don't want to do that.
I'm currently in the process of trying to install Win7 on my Macbook Pro (purchased July '07) using an ISO burned to a DVD with Disk Utility. Unfortunately, the DVD isn't bootable, and while the symptoms match what's in this blog post, the author's solution involved using a Windows-only program.
I'd like to know if it's possible to re-burn the ISO without the version number in the filenames as in the original solution, but with Disk Utility or something else that a Mac can use.
