MacBook Pro :: Cannot Make Changes To System HD - Partition Layout Greyed Out

Mar 5, 2012

I recently reformatted my entire drive and reinstalled Lion with the official Lion USB recovery tool/usb. Now in disk utility the Partition Layout option is greyed out and I can not seem to re partition my disk. I´ve tried repairing my disk rights but still its greyed out.

I ran a demo of iPartition and this message was flagged:

"You cannot make changes to the disk from which your system booted.

To make changes to this disk, you should either boot from an external drive, use Target Disk Mode with another Mac, or create a bootable CD/DVD." Does this mean I can only make changes with it when booting with the usb? This doesn´t make sense as it worked on the default startdisk before. Does anyone have solution?

OS X :: 10.5 System - Partition Inactive - Make Active Again?

Mar 10, 2009

I am using an EXTERNAL seagate 250gb drive formatted with the apple partition map on a osx10.4 system with no problems (intel based). I then plugged it into a 10.5 system (ppc system), it displayed some message which I ignored, perhaps to my peril, and began to backup some files and the transfer was moving quite slow. The drive was unplugged before the transfer was completed. I now try to use the drive on my 10.4 system and even-though the partition is still visible (in disk utility) it is not active (the drive is in black font but the partition is in grey font). Did the 10.5 system possibly make the partition inactive, if so how to do i make it active again? When I attempt to verify the disk, it reports that there is an "INVALID SIBLING LINK" and tells me that the volume needs repair. I try to repair the disc and it fails "INVALID SIBLING LINK" and the "THE UNDERLYING TASK REPORTED FAILURE ON EXIT" I would really like not to have to take this to a data recovery service and I am not tech challenged so I don't think I need to do this as the Hdd didn't fail, I hope.

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.

Info:
Mac Pro, OS X Mountain Lion (10.8.5)

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?

iMac, Mac OS X (10.7.3)

So if I have 10.6 installed and want to install Windows on a Mac, how can I create a 3rd (shared) FAT32 partition without reformatting the hard drive? I know how to without reformatting, but is there any way to just split my current partition into 2? I know how to do this on Windows, that is by shrinking the partition, but is there any similar function on a Mac so I don't lost existing files?

OS X :: Unable To Make Any Changes On System Preferences / Put Parental Control On System

Mar 29, 2010

could not be sure whether the Admin user - password reset with the CD would be the solution to my question as suggested in previous threads I searched - and have no idea where my start up install CD is

So my question-

I was trying to put parental control to ask for password when my computer starts up. I did something I guess and messed up the info.

I can log in with my own account when I restart my apple - which says now it is a standard account (must have messed that up)- but can not make any changes on system preferences or anything else that requires login and password. It requires Admin info. My own login that I use now used to be my admin so do not have any other info set.

now on system pref - accounts - an account titled "test" seems to be admin but can not even access that and reverse myself to be the admin since I can not unlock system pref. Or cant click on "Login Options" for the same reason.

There are no other users on this computer than me.

What do I need to do to make myself admin again?

Hope this was somewhat a clear question

MacBook Pro :: Creating A 3rd Partition For An Operating System?

May 30, 2012

So I have a Macbook Pro (15 inch, ~late 2011, 10.7.4) with a Windows 7 Boot Camp partition. I need to run a software for work that is only compatable with Snow Leopard, so I was thinking about trying to create an additional partition that has Snow Leopard, for a total of 3 partitions: Lion, Snow Leopard and Windows 7. However, when I went in to create the 3rd partition, I came across the following warning:This disk appears to be paritioned for Boot Camp. Changing the partition map may make this disk unbootable using Windows. I did a quick search online but didn't really get any clear cut answers on what could happen. Is what I want possible without wrecking my Windows partition?

OS X :: How To Make A FAT32 Partition On The Internal HDD

Jun 20, 2009

What is the best way to make a FAT32 partition on a MacBook's internal hard drive? (I plan to use it to share files between OS X and Windows.) I did some research on this, and some people say to use Disk Utility, however, the only disk format available for me is "Mac OS Extended (Journaled)" and there are no FAT32 or FAT or MS-DOS options. Perhaps those options were taken out since then(?). One other person said to create the partition using Windows, which I think would work, but I'm a little worried about that because I've read that editing partitions outside of OS X can prevent Boot Camp from seeing the partitions.

I'm thinking that my best bet would be using Windows to shrink its own partition, then turning the resulting unformatted space into a FAT32 partition. Since I'm not touching the OS X partition I'm hoping there wouldn't be any problems. I just wanted to confirm whether or not that would work and/or what a better method would be.

OS X :: Shrinking HFS To Make NTFS Partition Bigger

Sep 8, 2009

All I want to do is simply shrink the size of my HFS+ partition and make my NTFS partition bigger. I tried CampTune but it doesn't detect my hard drive (common problem). I'm going to try iPartition soon. In Windows, resizing partitions was a snap. Doesn't seem to be that easy in OS X for some reason.

I was gonna try Disk Utility but it says that it may make my Boot Camp partition unbootable. I don't really want to take a chance. I just made my HFS+ partition smaller in boot camp, but it won't let me touch my NTFS partition. I'm thinking about going into Windows 7 and using Disk Management to extend the NTFS partition.

Windows On Mac :: Reinstall - Remove Partition And Make New One?

If I wanted to reinstall Windows (currently using 32bit, want to upgrade to 64), I assume I would remove the partition, make a new one, and reinstall Windows from there. Now, will the same Product Key work if I did it like this? As far as I know, because the Product Key has already been used it won't let me.
