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.

OS X :: Disk Utility Erased All Data?

May 22, 2009

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?

OS X :: Disk Utility Partition Erased Hard Drive?

Nov 12, 2009

I was making a partition on my USB external drive in order to put a disk image of Snow Leopard on it, so I could boot off of it.

I added a 10GB partition to the drive, and clicked Apply. The following dialogue box came up:

Partitioning this disk will change some of the volumes. No volumes will be erased.

This volume will be added:
"Snow Leopard"

This volume will be resized:

I clicked Partition, and it finished very quickly. I checked Finder, and the entire drive, BOTH partitions are completely empty.

MacBook Pro :: Can Use Disk Utility Recovery To Clone Original Hdd To A New One

Apr 16, 2012

My original hdd refuses to boot up, and using disk utility via recovery mode to try and fix it just gives me an error "disk utility stopped repairing the drive, salvage data and format etc." giving an error about invalid node structure or something. Tried using target disk mode with a friend's mac when I was at work but the drive didn't even want to mount. Assuming it's about to die, I have just bought a new hdd (XT Hybrid) and since my mac is pre-Lion era (2010 model) I don't have a built in recovery mode, but strangely enough hooking up my old hdd with a dock and option-booting to it I can still access the recovery HD partition on it. 

So I was thinking if i can essentially "clone" my original hdd to the new one using the restore tab on disk utility, and try using disk repair on it to get it working? or is there another app I can use that will do this (being mindful that I don't have access to another mac or the OS on the HDD to run it, so it'll have to be "live", and preferably free) Or should I just cut my losses and just put a fresh install on it... Yes I do have a time machine backup, but there's two reasons I want to see if this works - one is that although time machine is quite up to date (within a week I'm guessing, can't remember), it's obviously won't have the new content created during the day(s) before I was able to plug in my external hdd, and secondly since I don't have access to another mac to create a lion install usb drive, I'll have to use the internet recovery, and knowing my internet connection, 4gb download would take probably overnight and nearly a whole day to finish (assuming it doesn't drop out).

OS X :: New HD Not Showing Up In Disk Utility - This Volume Is The Startup Volume And Cannot Be Erased

Aug 10, 2009

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.

OS X :: External Hdd Not Showing Up Even In Disk Utility?

Aug 15, 2009

I've been having trouble with my Western Digital 160GB HD, its one of the MyPassport ones or what not. It used to work like a charm and had for a while but a couple of days ago it just stopped being able to be read or even recognized on Macs. I tried this laptop and another macbook pro and both would not show the HD on the desktop or even Disk Utility. When I open the Disk Utility when the ExHD is plugged in, I just get that loading circle and it will just do that indefinitely. Same thing with System Profiler as well.

I don't believe I damaged it in anyway, I hear no clicking and it seems to "boot" smoothly when it's plugged in, so would this mean its a corruption issue? I have been plugging this in to different Macs recently, (3 total) and one of which runs Leopard while the other two run Tiger. Would that cause the issue? (the reason I ask is that this all started after I had plugged it into the different OS.) I haven't tried to plug it into a PC yet, i'm going to do that today but I had tried doing the CMD + Option+ P + R reset till the second beep and I also did a hard reset by unplugging everything and waiting a bit then holding the start button down until it beeps.

Hardware :: Reformatted HDD Using Disk Utility?

Feb 2, 2010

I reformated an Edmini with disk utility... which I know sounds stupid, but the ethernet port wasn't working... or I couldn't connect to it through ethernet. So I connected it through the USB port and reformatted it.. and now I believe i've turned it into a paper weight. Does anybody know of a way to fix it? To atleast put it back to where it was (only connecting through the USB port?)

Applications :: Disk Utility Freezing / External HDD Not Working?

Oct 11, 2010

I bought a WD My Passport 071A Media 1TB External Hard drive yesterday and was hoping to use it for my Mac and PC laptop. So I plugged it into my mac and it asked me if I wanted to use it for Time Machine and I said yes. It reformatted it and then I realised i wanted to partition it so I went to Disk Utility and split it into two partitions, one 50GB for Time Machine and another 950GB for my other storage, and made that FAT32 format. So I copied a song onto that partition and noticed it was copying really slow, so I copied the same song to the 50GB partition and my other 1TB non-portable hard drive which is also FAT32 and it was normal speed. So I thought I should try removing the 50GB partition and halfway through my computer froze and I had to reset it. Now my hard drive won't work in Mac or Windows and when I open Disk Utility, I see it there but when I click on partition, it freezes and I have to Force Quit the application.

The HDD works well with the MAC however it will not mount on a windows XP machine.

The hardware detector detects the USB external harddisk but is not able to mount it. When i use the Windows Disk Management Utility, the hard disk appears with a (Not Initialized) and Unallocated warning message.

Power Mac G5 :: Internal Hdd Disk Utility / It Will Be Completed In 1 Minute

Dec 3, 2007

I just installed a Hitachi 1TB drive in my dual 2.5ghz powerPC G5.

I carbon copied my old harddrive over to it.

I didn't want to reinstall my OS.

However I think I copied some problems over.

In Disk Utility when I try to Verify Disk Permissions, Verify Disk, or Repair Disk Permissions (any of the options I am allowed to do to the startup drive) it moves like 1/5th of the time bar meaning it is working then changes to "It will be completed in 1 minute" then stalls there.

30inch Apple Cinema Display, 4.5gb Memory, and 1.5TB of Harddrive.

Applications :: Disk Utility (Leopard) Resizing Partition On External HDD

Mar 24, 2009

I'm trying to use my 500 GB external HD as solely a storage drive now whereas it used to be storage and backup, with separate partitions for each. I have deleted the backup partition (the first partition) successfully with Disk Utility, but how can I resize the remaining partition into the free space before it on the disk? I can't drag it or enter the desired size in the text box, it doesn't seem to want to get any larger. Is there any way to do this without purchasing ipartition? I have an old version from Tiger, but I'm not sure if that will work safely on leopard, and I do not want to lose my rather larger collection of ripped dvds on this external drive. Here's a screen shot of what i now see in disk utility.

OS X :: Burn ISO To USB Or External HDD With Disk Utility - Error 254

Jul 28, 2009

I am desperately trying to burn a ISO file to a USB and external HD but Disk Utility does not want to. Instead I get the error message "Could not validate source - error 254". So there must be a problem with the source which is the ISO file.

I already tried setting the Partition Map Scheme to both Master Boot Record and GUID Partition Table. I also formatted the drive to FAT and HFS+. I cannot find the cause of this error. It clearly looks like Disk Utility does not like burning ISOs to USBs or HDs.

However, I really really need to this since I cannot burn ISOs with my SuperDrive which is also a common problem [URL]with my MacBook Pro.

MacBook Pro :: Lion On Ssd Crashed - Disk Utility 'cannot Repair The Disk'

Apr 25, 2012

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!

Mac Pro :: Scratch Disk Partition And Size With Disk Utility

Sep 8, 2010

My new 2010 hexacore Mac will have 24G memory, an OWC Extreme Pro 120G SSD (positioned in the lower optical bay) and four 2TB WD RE4 drives. I'll use my old Synology 209 NAS (two 1TB WD Green Raid 1 drives) for TM backups over 1000Mbps Ethernet. Yes, I'll need to upgrade to a larger NAS very soon. This will be my first Mac Pro (have MBPs and iMac) and will be used for web design and development (mostly Adobe CS5 products).

The SSD will be used for boot and application files. I plan to use Disk Utility to create a 1+0 Raid array for data files. For a Scratch disk, should I:
1) create a partition on the 1+0 Raid Array for Scratch
2) partition a chunk of the SSD for Scratch
3) attach a spare external 2.5" WD drive via Firewire 800 for Scratch

Based on my reading, it seems that option 1 makes the most sense but I'm not entirely sure if you can partition a 1+0 array with Disk Utility. I'm pretty sure option 3 is quite silly but wanted to toss out the idea. Lastly, are there any generic recommendations on scratch volume sizing?

Mac Pro :: Need To Repair Disk But Disk Utility Won't Allow?

Feb 3, 2009

I live in France and my nearest authorized dealer is 200 miles away, so I've been on the phone with support a couple of times and gone through various hoops.

Two days ago, my hard drive (or CPU?) started acting up. My Macbook Pro (bought May 07, 2.16 GHz, running 10.4.11) took a long time to boot, and then my desktop image appeared as a fragment along the top of the screen. Various processes started to hang the machine, during which time a repetitive sequence of ticking could be heard from inside the machine until whatever was wrong resolved itself. There were no program crashes and in fact the machine operated fine inbetween these hangs. I ran an extended hardware test, no problems there. Disk Utility, however, would not complete its verification, saying "the underlying task reported failure on exit". It stated that the HD needed to be repaired. However, the "repair disk" button was greyed out, disallowing the repair.

TechTool showed the directory scan failed, as did the volume structure test.

I tried numerous times to Safeboot, but the computer crashed (simply turned off suddenly) midway into the boot each time.

Apple Support had me zap the PRAM, clear the caches, and do that 15-second power-button thing with the battery out. All the log-in items that might have been slowing the boot were removed. This succeeded in getting the machine to boot faster and the desktop image returned.

However, both Verify Disk and TechTool showed the same problems, saying the disk needs to be repaired.

I have since backed everything up and would like to try to resolve this myself rather than driving it to the service centre. What are my next steps? I'd like to somehow avoid a clean install and have to reload everything

Mac Pro :: Disk Order In Disk Utility Messed Up

Jan 1, 2010

My Mac Pro has been acting strange on boot lately. When I hit the power button, the fans rev up normally, then there is a pause, the Apple chime sounds and instead of instantly getting the grey Apple boot screen the screen stays blank for about 20 seconds. Then I get the grey boot screen. I tried resetting the video controller by unplugging all things connected to my Mac Pro, unplugging it from the power source and then rebooting with nothing plugged. Didn't solve the issue.

After this odd startup, the computer boots into OSX fine. The OS works great. It's been over two weeks since I installed AHCI on Windows with gugucom's method and haven't had any problems since and none now except for this boot issue. MP boots into windows 7 fine. Only thing is that in SL when I hit shutdown or restart the MP doesn't always do so right away.

Furthermore, I just took a look in disk utility and the order of my disks has completely changed. My initial disk order was:

disk0: Macintosh SSD (BootDrive)
disk1: Win7 SSD Bootcamp
disk3: 1.5TB WD Backup
disk4: 640GB stock Apple HDD

Now Disk Utility reads:

disk0: 640GB stock apple HDD
disk1: 1.5TB WD Backup
disk2: Win7 SSD Bootcamp
disk3: Macintosh SSD (Boot)

How can I fix this boot issue. Can this be caused by the patching of my Win7 MBR for AHCI install even though I haven't had issues until yesterday? Any ways on how to fix this. If this may help... I have a 2.0TB WD HDD set up in Time Machine with several backup points however I have been working on a powerpoint project in Windows. Will a restore (if necessary) also restore my Windows drive to a previous date or not? Any help is welcome.

MacBook Pro :: No History In Disk Utility?

Apr 12, 2012

My disk utility is not showing any history or notes of any kind when I try and repair or verify permissions.  This is a new devlopment, I used to get a lot of notes about issues being fixed or being unfixable.  My computer is also running slowly - particularly firefox and mail.  No other issues to note.  I have a MacBook Pro running on 10.5.8

I am wondering what course of action is best to take next.  I could buy a copy of disk warrior.

I could also upgrade to Snow Leopard.

MacBook Pro :: SD Card Not Mounting Or Seen In Disk Utility

Aug 23, 2010

I have a mid-2009 13" MBP (2.26, 4 gigs, 1TB HDD, SL 10.6.4) and the SD card reader is not recognizing any of my SD cards (won't mount and also not seen in Disk Utility). The cards are recognized when using a USB adaptor, and also work fine in my wife's MBP SD card reader, so I know it's not the cards. System Profiler recognizes the internal card reader on my system.

I've tried resetting the SMC and reformatting the cards but nothing has worked so far.

EDIT: The SD card reader isn't working under OSX or in Windows, btw.

MacBook Pro :: Internal HD Not Recognized Even In Disk Utility

Nov 3, 2010

I have a 2009 13 inch macbook pro with 2.4 ghz processor, 4 gb ram, all stock from apple. Machine has been working great until 2 days ago when my system froze, had to push the power off button, tried to reboot but got the flashing folder and the internal hard drive was no longer recognized. I did all the usual things and read the apple support page to no avail. I booted from the install CD and the drive is not recognized in disk utility. I took the drive out, put it in an external case and booted from there and the drive appears to be working.

I put in another internal drive, a Hitachi 500 GB/7200 RPM that looks mac compatible, disc utility will not even recognize it either with the external hard drive OS running or from the install CD. In system profiler, under hardware, it says this computer doesn't contain any ATA drives. Could this be a problem with the SATA cable internally? The rest of the logic board appears to be working as I am typing this on the affected machine running the OS from my former internal hard drive that is now in a casing.

MacBook Pro :: HD Gone From Disk Utility (Failed To Copy)

Sep 21, 2009

I've got a problem with my MBP. It finally came back from repair centre today. My Harddrive was broken, so they put a new one inside. Everything worked OK, until I decided to install Snow Leopard, and after that put my superduper backup from my external HD to the MAC hd. I restarted the MAC while I kept holding down the "C" button, (snow leopard disk inside) I went to install OSx menu,-> Disk utility-> MAcintosh HD->last TAB (can't remember the name)-> and dragged the External HD in the first bar, and mac HD in the Second. Also I checked Remove Mac HD when copy the Backup to MAC HD. I pressed the button and the EST time was about 2 hours. After one hour my HD made some noise and gave me an error: Something with Failed to load or Failed to copy. After that it did removed my Macintosh HD drive. It's just Gone! I don't know what to do.. Can't install my mac it's completely useless right now..
Here are some pictures describing the situation:

MacBook Pro :: Unable To Repair Disk Using Its Utility

Mar 14, 2012

Lately, my MacBook Pro (mid 2010) started to slow down even with over 60% disk space is empty and max RAM is installed. It gets slow when using hungry programs such as Photoshop CS5.

I used the disk utility first aid and fixed all permissions that were shown with errors. When scanning the disk, I received the message that my disk is corrupt and I need to fix by restarting with command+R keys pressed until the apple symbol is displayed. When the next window shows up, choose disk utility and go from there to fix the disk.

When I performed that, I let go of the Command+R keys after the apple logo came up, the only thing that came up after that was a grey circle with a diagonal line through it and a spinning clock.

MacBook Pro :: Disk Utility Says The Volume Needs To Be Repaired

On one of our MacBook Pros (Late-2011), running the latest OS X 10.7.3, Disk Utility says the volume needs to be repaired. When I use Disk Utility from the Recovery HD, it says the volume appears to be OK. I verified by using fsck in single-user mode, and it found no problems either. Which do I believe? Is this a sign of a soon-to-fail hard drive?

MacBook Pro :: Disk Utility Keeps Crashing On Launch

Jun 20, 2012

I have a new macbook pro 15.5 and had it for 3 months after which the hard drive crashed. There goes the illusion that nothing ever happens wrong with apple... especially my first one which I treated like a baby. So it was taken into a support center, they cloned my hard drive and ordered a new one... 22 days later I get my mac back and everything seems in order. Except when I run Disk Utility it keeps crashing. Funny enough when I run it from Recovery mode from boot its fine. But when logged into the OS (Lion) it launches and starts gathering information.Then crashes and I get the submit fault dialogue..Anyway here is the log. I have run Onyx, applejack etc but the problem has not been resolved.[code]
