OS X Mountain Lion :: Couldn't Repair Partition Map Because New EFI System Partition Couldn't Be Created

Jun 4, 2014

Time machine reported an error and couldn't back up, so I ran disk utility on the time machine drive and got this message.  

"error: couldn't repair the partition map because a new EFI system partition couldnt be created." 

Then I hit verify disk and got the message  

"Error:  partition map check failed because no slices were found."

OS X V10.7 Lion :: Repair Boot Partition But Don't Have 'Recovery HD'

Jun 3, 2012

I was doing a routine maintenence and Disk Utility is telling me I have a few block counts askew. Everything seems to be working fine ( on the surface of things ) but like to be anal and would like to do a repair. However, I don't have a Recovery partition and the App store has decided that I haven't purchased Lion although I did, I can show you the bank statement. I installed a new hard disk not so long back ( I guess this is the reason why the App store decided I didn't purchase Lion!? ) and reinstalled from a Time Machine backup it wasn't seemless but I'm techy enough, to make it work, just not a big fan of spending my days learning terminal commands.I have a mid 2009 MPB so can't do internet recovery, the Recovery Disk Assistant won't let me create a Recovery Disk on an exernal drive since, yes you've guessed it, I don't have a Recovery Partition.

Am quite happy to reinstall as long as it doesn't compromise my data but can't find the 'restore my purchases' button on the app store else if there is a less than obtuse ( and none-sketchy ) method of creating the partition HD.

I have a 4TB internal drive in my Powermac. It currently has two partitions: one that is about 270GB that is almost full, and one that is 3.7GB, that is about 25% full.  

Disk Utility will not let me add a third one, however. The drive is NOT a fusion drive.

OS X Mountain Lion :: Can't Partition With Disk Utility - Options Greyed Out

Dec 4, 2014

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. 

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. 

I am starting to believe the disk is damaged. Beside the partition problem the disk is behaving fine.

OS X Mountain Lion :: Trying To Delete A Partition But Subtract Button Is Greyed Out

Aug 28, 2014

I have a 3 TB hard drive which I'd previously partitioned into a 1 TB and a 2 TB partition. I've emptied and erased the 2 TB compartment, but when I go to the partition section on Disk Utility, and select that partition (now called Free Space) and select it, only the + button is alive, and the - button is greyed out. 

How can I delete this entire partition?

OS X Mountain Lion :: Bootcamp - Create New Partition And Format In Windows 7

Aug 27, 2014

I have Windows 7 installed on my sons MacBook Pro. 

The Drive is partitioned at 500GB for Windows and 300GB for Mac.

In windows, I need to shrink the Windows drive, and then create 2 extra drives from it.

However, I can shrink the drive, but when I try to Format, it tells me that it cannot find the drive, and then it changes the drive types to all "Dynamic" including the Mac Drive.

And once this happens, I can no longer access the Mac drive during Boot, and windows will not load, as it cannot find the drive during windows boot up. And which point, I have to restore the system and it takes up to 6 hours to installed Lion, as my Internet is slowing that a cold winters day. 

So, my question is the following.

How can I successfully shrink the drive.

Then Partition the FREE space

Then Format to NTFS without loosing drive type and integrity?

Windows On Mac :: Can Add More Space To A Partition After Its Created

Sep 15, 2010

I installed windows 7 on a separate partition using Bootcamp.
Thing is, I changed my mind and I want to add more space to this partition. Is there any way of doing this?

Also, now that I have Windows 7 installed. How do I change from one to another? I thought there would be an option at startup but it just goes straight to OSX

Windows On Mac :: Partition Created Didn't Show On OS

Feb 8, 2009

I used bootcamp to create a partition for installing Windows.

Everything worked fine and I still see the Windows partition on Mac OS.

But when I used Disk Management on the Windows and split its partition to 2 new partitions (C: and D: on Windows), they didn't show up on the Mac OS. The Mac OS still showed the Windows partition as one (which is created by bootcamp), not two.

I'm using Vista Ultimate with and Mac OS X 10.5.2.

MacBook Pro :: OS Lion Couldn't Access Guest Account And New User Account

May 24, 2012

I bought this new MacBook Pro a month ago.  When I try logging into my guest account, it froze.  I had no other alternative but to get out of it by pressing the power button.  Then I tried open a new user account to see if it also has the same problem.  Unfortunately it did have the same problem - froze after I logged in.  I had done a harddisk check, there seemed to be no problem.

Intel Mac :: Erase Hard Drive Mac OS X (LION) "Couldn't Unmount Disk"

Apr 15, 2012

I've just transferred my data to a new computer and now need to erase the hard drive on my old one.. I've tried Disk Utility, increased the security, and tried 'erase' but I keep getting an error message "couldn't unmount disk". I've gone into Partitions and tried deleting the HD there as well but I get the same message. I just want to get the computer securely wiped and would like to keep Lion as the operating system.

OS X V10.7 Lion :: Disk Utility Can't Repair Disk (1 Partition) On External Hard Drive

Apr 24, 2012

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.

OS X :: Couldn't My Mac Be Accessed Via Airport?

Sep 20, 2010

Airport is turned on my default and I think that is totally unsafe. I didn't use a strong password when I first got my Mac, and that part is my fault. But what is to keep someone from accessing my computer wirelessly through Airport when it was turned on and I had that weak password? And even if a person didn't want to access my computer, if their computer was infected with malware or whatever, what would keep an automated program from guessing the password and connecting to my computer or anyone else's?

OS X V10.7 Lion :: How To Use Disk Utility To Repair Encrypted Disk Partition

Apr 6, 2012

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?

OS X Yosemite :: Regain (free Space) Partition Created By Bootcamp Failure

Dec 3, 2014

I am using Bootcamp trying to install the Windows 7 and it went alright until rebooting and starting to install procedure. The computer cannot read my flash drive and finally ended up with installing failure. Then I tried rebooting several times and suddenly the bootcamp partition (with nothing in it actually) cannot be read. 

I came back to OS X and tried to delete the bootcamp partition but after a while failed. Then I cannot see the Bootcamp Partition in Finder. In disk utility it became "Free Space (I'm using Chinese system and it shows "可用空间“ in both name and format)." 

Cannot be deleted through the minus button, cannot be formatted, and all the options are grey (cannot be clicked) 

In recovery mode (command + R) it remained the same. 

I can normally use the other partition in Mac OS X. 

How can I delete the unusable partition and regain the space? To combine the two partitions back together is the best choice but HOW?

I'm trying to install OS X Lion on my 27" iMac.I've erased the HD using Disc Tool in recovery.HD shows no errors.I've tried Internet Recovery (it loads up, but wont start the installation)I've tried creating a recovery usb on another similar iMac, and use it on this. Same error, only differance is it keeps "loading" when installing, but nothing happens. Same error in log. When I try to start the Reinstall I get an error in the installation log that goes something like this:

OS X :: Couldn't Eject External, Now Disk Not Mounting?

Aug 15, 2009

I know this has been disccused ad nausium many places, but in reading 100s of posts Ive just confused myself and was hoping someone could help me make sense of all I've heard.I have a ibook g4 and use a WD 500gb external hard drive to keep all my music/pictures etc.Last night when I was moving files around (I dont think it was actually in the process of transferring files when this occurred, but there is a slight chance it was) I accidently hit enter instead of shift which told my computer to open all of the 1000+ folders that I had selected (DOH!) after working for an hour it seemed to be all frozen so with concern I turned the computer off and restarted.Suprise suprise, my external will no longer mount. - Disk Utility recognizes it but says there was an error on exit.Tim

MacBook Pro :: First MBP 13" 2.4GHz Couldn't Be Happier?

Apr 28, 2010

I decided earlier this year that I was going to get a Macbook Pro to replace my ugly tablet and it's terrible, grainy screen. I knew there was a pending refresh and so I waited and waited and finally the refresh came. I quickly put a bunch of stuff on eBay so that I could order my new MBP and it arrived this morning.My first reaction was "Wow, that's a small box". I opened it and I quickly noticed how solid the computer was and the lack of tacky stickers all over it was refreshing. I turned it on, set it up and began to play. The first thing that I noticed was odd was that there was no true maximize button. I kept wanting Chrome to take up the whole screen, but I quickly realized that the window was the perfect size to fit the content, if it were larger I'd just have lots of blank white space on the right side. This way is clearly more useful.
