If you are able to mount the drive, you can use Copy Copy Cloner or even better (IMO) SuperDuper! from Shirt Pocket. SuperDuper! will not copy caches and unnecessary files that are re-created upon boot, saving space. These both give you clones of the drive, but not images. If you can restore the clone, then this might work. If you're savvy with a Terminal, ...

The short, simple answer is DeployStudio. It's free and it's built for the exact purpose of creating and deploying OS X images. It can run in a standalone configuration or it can be configured on a server to capture and deploy images over a network. It has a host of post-flight operations available including performing Active and Open Directory binding. ...

Just let it sit - I have the same EXACT situation and while I was researching online, it just "popped up" and was available. It seemed like my good computer was trying to fix the bad computer first, before it mounted as ext hd. Hope this helps.

The issue persisted across multiple macs but Windows 7's Disk Management tool didn't seem to have any issues creating a new partition table. Afterwards the drive worked as expected on OS X.

If disk utility does not even see it the electronics in the drive may have failed. System Profiler may show a drive there but if disk utility cant access it, well... "Houston we have a problem." If it IS an external you could try unplugging any other USB devices and/or trying another USB port and possibly even a different USB cable. If you can easily open ...

The message from Disk Utility is simply there to tell you it's checking the hidden EFI partition (if present) and updating as necessary. In your case it won't be necessary so nothing will be updated. Disk Utility performs this extra step if you run a disk repair on a parent disk rather than on one of the partitions within that disk.

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; ...

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 ...

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 ...

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 ...

The kernel: disk3s2: I/O error is indicative of a disk going bad and you'll need to replace the disk and rebuild the disk array in order to retrieve the data. Consult the user manual for the product on how to rebuild the array so you don't loose any data.

I discovered while in recovery mode that pressing "apply" when attempting to partition the disk that has been booted from shows an error message saying something like "cannot partition the disk that has been booted from". I imagine this will be the same error that appears while the system is live, but I didn't want to hit the Apply button to find out. ...

You have to boot from another device or to Internet Recovery Mode and then use the command line to modify the CoreStorage volume. Preparation: Backup your data. Detach any external drive (especially your external Time Machine backup drive). Restart to Internet Recovery Mode by pressing alt cmd R at startup. The prerequisites are the latest firmware ...

You've selected the Master Boot Record option. Only 4 primary partitions are allowed. disk2s5 and disk2s6 are actually extended partions. You cannot change the name conversion via DiskUtility. If you select GUID Partiton Table option, you'll get this: $ diskutil list disk2 /dev/disk2 #: TYPE NAME SIZE ...

There are no obvious reasons to convert parts of the main drive(s) to a CoreStorage scheme - except for Fusion drives and FileVault 2 encryption - until now. To convert your classical to a CoreStorage scheme boot to Internet Recovery Mode, Recovery Mode or an external bootable (thumb) drive, open Utilities/Terminal in the menubar and enter: diskutil list ...

Disk utility can't resize the last partition on a drive. One way would be to use GParted to move the partition and then resize it. Boot the Mac with a Ubuntu Live CD. Run GParted and move the second partition to the beginning of the free space; Reboot to Mac OS X. Verify and repair the external disk with Disk Utility. It found a minor error on the volume ...

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 ...

This could have been a situation where the PRAM somehow lost the startup disk settings. If you reboot holding COMMAND-OPTION-P-R and wait for the startup chime (or two) that will reset the PRAM and might fix the issue. What you did was exactly right, however, as there might have been disk corruption or some other sort of disk problem. Unfortunately disk ...

[Edited to reflect screen shots] Technically that is 1 Hard Drive and 4 partitions (see how they are all indented from the drive they are in). It looks like someone enabled showing all volume types in your Disk utility so it's showing you things not normally shown in the GUI. OS X has something like LVM so you are seeing the Logical Volume (LV) and the ...

DiskWarrior is brilliant at repairing file system issues that Disk Utility can't manage, but if you're not bothered about repairing your existing file system then you may as well wipe and restore. In addition the above answer I'd strongly recommend creating a USB installer so you can boot from that and then properly repartition and reformat your SSD. ...

You file system is corrupted, hardware is probably fine. Backup, wipe and restore.

This should be one way to regain your unused space. There might be a better (or more elegant) solution, but since i don't have a spare Mac at the moment (and it doesn't work in a virtual environment) i can't figure that out. The solution outlined here removes any partition which obstructs the expansion of the CoreStorage Volume Group. Then the physical ...

I've had mixed success using that bootmaker utility. Try Apple's instruction here https://support.apple.com/en-us/HT201372 Assuming a) the 'install osx mavericks' file is in the Applications folder and b) your USB drive is named MyVolume, open Terminal and run this command. sudo /Applications/Install\ OS\ X\ ...

If you've installed Yosemite it will automatically have created an invisible recovery partition and so you may as well delete the recovery partition you created. Keeping a copy of the Yosemite installer on a USB stick is definitely a good idea though in case your drive ever dies or you need to perform a clean install (on an SSD for example). Alternatively, ...

"erase" the disk as MSDOS then you can delete it.

go to the partition, mine was named disks03, i then went to the ERASE tab, then select security options, here i raised it to the max option which said something about the standards of U.S department of defence. once you've set the security option to max, hit erase, and it begins the purge! Worked fine for me
