After gaining some experience with CoreStorage volumes, I reworked my first answer to generalize and facilitate it by adding some scenarios and deleting some dispensable steps. Basically there is one undocumented command to resize or expand a CoreStorage volume group and an inherent logical volume: diskutil cs resizeStack LVUUID size The command ...

I suspect Windows` chkdsk or another Microsoft tool to erroneously repairing the partition table of your device containing the EXFAT volume. The result of sudo gpt -r -vv show /dev/disk2 of my 4 TB device created in a VM and formatted with Disk Utility in comparison looks like this: gpt -r -vv show /dev/disk2 gpt show: /dev/disk2: mediasize=4000655081472; ...

Although I don't know what specific property of HFS+ allows a user to modify the current system partition while in use; my expectation would be that operations to blocks of storage that the filesystem is not currently utilizing are allowed. Now if you tried to shrink the system partition below the current size of your system installation (the blue shaded ...

You can recreate the EFI System Partition (ESP) using the command-line tool gpt. Since you have to modify your current start device you need to boot to Internet Recovery Mode or an external (thumb) drive. Additionally you need a valid EFI-partition or an image file of it. Here is a similar question: How to fix broken EFI partition?. I have copied some of ...

In my opinion "TestDisk" hosed your GPT. Please compare the TestDisk result with my disks. The disks in my example are equally sized, disk0 contains a CoreStorage partition and disk2 an old-style JHFS+ partition. I'm using two separate disks because it's unknown (at least to me) which formatting type (CS or JHFS+) was used originally. The PMBR/GPT and the ...

This Ask Different post has what you're looking for. Don't go looking for an "answer," the author for some reason decided to write his own answer in the "question" post. The method worked perfectly (and non-destructively, but you should always take a backup anyway, just in case) for me! Paraphrased: Reboot in Recovery Mode by holding down Command-R ...

I just made an installer image for OS X 10.10 to install in a virtual machine and it's only 5268873216 bytes or 4.90702 GB in Base2, in Base10 it's 5.27GB. So you could have made it smaller. Not sure if you can resize it, you can try and if not delete it and start with a smaller partition. BTW There does need to a just a bit of free space as it's written ...

The fastest way to solve your problem is probably adjusting the path of your user directory in the yourusername.plist (assuming following current path of your user folder: "/VolumeNameContainingYourUserFolder/Users/yourusername"): Boot to Recovery Mode. Open Terminal.app in the menubar (Utilities -> Terminal) Enter df to get the paths/names of your main ...

The only conclusion I can draw at this moment is that OS X Yosemite does not support hard drives larger than 2TB. Very wrong. Yosemite supports drives up to 8EB (exabytes. Or 8 million terabytes. You could download the internet with some room left over). What it has problems with is proprietary file formats from other companies, esp. if the patent ...
