I had the exact same problem and searched the web until I found this easy little fix, so I thought I should share it. First I made a backup of my primary drive with Carbon Copy Clone on an external drive. Then I restarted the computer, as it starts hold CommandS for just a moment until it starts to boot. At the prompt enter fsck -fy. Then let it do its ...

You can try the following programs to retrieve your data from lost/damaged partitions: FileSalvage, Data Rescue, Stellar Phoenix Mac Data Recovery, DiskWarrior. The good practice is to create an image of the actual partition and restore data from it.

Disk1 is a "virtual device" which resides in disk0s2 (the Apple_CoreStorage Volume Group which actually contains a FileVault volume). You have only one 'physical device' indeed. Disk0s5 is probably an old Bootcamp installation. The clean way (get rid of the 2 Recovery HDs): Make a complete Time Machine backup of Macintosh HD. Start to Internet Recovery ...

OS X Yosemite includes a recovery partition, the main one and a further one whose use i do not know but these are important so don't delete them. Sorry, you'll just have to work around it.

Chances are, it's just a folder created randomly by some app or another at some point to use as a mount point and it was never deleted. It should be perfectly safe to rm -rf it, especially if it is empty.

There is no need to delete the CoreStorage Logical Volume Group. Just resize it: Have a backup! Reboot into Internet Recovery Mode (hold Option-Command-R) as the machine is restarting). You'll eventually be presented with a Max OS X Utilities window. In the menu bar along the top of the screen, click Utilities -> Terminal. At the prompt, enter ...

Having exactly the same problem, i fixed it using the advise and command mentioned above: diskutil eraseDisk JHFS+ name disk0 The tricky part in my case was that the name of my SSD was not listed doing diskutil list command so the command would not accept simply disk0 (disk0 was my SSD). I tried to use"unidentified" and it worked: diskutil eraseDisk JHFS+ ...

Boot into Recovery from the USB. Instead of opening Disk Utility, open Terminal instead. Run the command diskutil list to see that your drive is being recognised. It should list two disks, one being your bootable drive, the other your SSD, and provide you with a disk identifier (such as disk0). If it doesn't show up, check that you have installed it ...

I/O problems are a good indicator that your drive is past its best. Replace the drive or do the following... Back up everything of value via Target Disk Mode (if possible) then boot your MacBook from a USB or DVD installer. Run Disk Utility, selecting the secure erase/zero fill option and wipe your drive. This will issue an ATA secure erase command that ...

Run the fstab command and remove all the setting there, then write the command. What I had there was preventing my Windows BootCamp partition from mounting. After removing it everything worked fine. http://www.cnet.com/how-to/prevent-a-partition-from-mounting-in-os-x/

Have you got access to another mac? Your best bet would be to connect other mac using target disk mode, either via firewire or thunderbolt. Your internal drive will show up on the desktop of the other mac for you to copy off your files. Other option would be booting up via an other system via an external drive, open disk utility and try to repair a couple ...

In order to increase your Windows partition, you will need to first free up disk space on your Macintosh HD partition, as it appears to be full. 128GB isn't very much these days, I would recommend getting a larger hard drive, but transferring larger, less frequently used items such as movies or videos can often help free up large amount of space.

Not sure if this will be helpful, but I just wrote a script to unlock and mount a core storage Encrypted Disk like yours for myself. I had the same problem where I could get the disk unlocked, but not mounted. I finally realized that I needed a command to mount it after it was unlocked. In terminal, you first have to unlock the Encrypted Disk and then you ...

You could try booting off a Linux LiveUSB to back up your files. Once that is done, you can reformat your HD and then reinstall OS X. You should also keep an eye on your HD; these types of errors often suggest that your drive is corrupted or damaged.

You should be able to delete the partition, and you would be able to re-use the space to create a new partition (of the same size). For some reason (not technical) OS X (lion or later) won't let you resize partitions on MBR disks. You could delete using gparted from a Linux live CD or many partitioning tools. You don't say what you are proposing to use the ...

If you use CarbonCopyCloner (after reformatting the SSD) it will give the option of moving across the Recovery Partition before moving your 500Gb of data to the new 1Tb partition.

The following diskutil cs resizeStack command is vastly undocumented and as such potentially destructive. Please backup your Mac OS X before proceeding.

The drive cloner did exactly what it was supposed to do – clone the drive, right down to the original volume's capacity. Try reformatting the SSD with one 1TB partition and then doing a standard Time Machine restore.

I found a (quite easy) way to recover the contents of my HDD. 1) I got myself the MBP from my nephew. 2) Connected it with a FireWire cable to mine. 3) Booted our MBP up in Target Disk Mode (press 'T' when booting up) 4) Our MBP then behaved like any external storage device and the files could copied off just like that. In that way i got all the important ...

Usually when I see this error it is because something on your Mac is accessing something on your USB drive. It can be as simple as having the USB open in a window, or Spotlight trying to index it. Try and select the USB drive in Disk Utility and Eject or Unmount it from there. It may say it can't be ejected and ask if you want to Force Eject it, say yes, ...

Try booting from a USB drive. Internet Recovery uses the local disk to temporarily store the image, which it won't let you delete. via

I have solved the problem connecting the disk directly via SATA, I didn't have a Macintosh to install a 3.5" disk into, so I connected it to a PC with Windows 7, installing the HFS+ drivers, which allowed PC to see the disk and read (but not write) the data on it. I was able to copy the data to another external disk which I formatted into exFAT, so it could ...

error 22 is the EINVAL in libc error codes. Maybe your glibc is corrupted? I think you can reinstall it from Xcode based on this question http://stackoverflow.com/questions/9353444/how-to-use-install-gcc-on-mac-os-x-10-8-xcode-4-4

So I tried running disk verification with the volume unmounted and verification occurred without getting stuck as before. You can unmount a volume from Disk Utility (don't eject it), but if it's your system volume then you'll need to boot into the recovery partition (hold Command + R during start-up) as the volume won't unmount otherwise. I still can't ...

You cannot erase the currently-running volume. Shut the computer down, restart while holding the option key, and choose the Recovery HD. Find Disk Utility in the menus and you will now be able to erase your internal storage.

Firstly - Sorry for bringing up an old question - I just spent a year trying to find the answers and only found questions so I figured I'd answer a past one with my solution Resize Bootcamp partition 1) Boot to MacOS and use disk utils to shrink MacOS partition leaving unallocated space on hdd <-- I believe you are at this point based on the empty space ...

I figured it out! Open Disk Utility. In the left-hand panel, select the disk image you would like to resize (the DMG file), then click the Resize Image button in the toolbar, and then enter the new size. Click Log to ensure that it resized successfully. Click Open to mount the volume. (You may also mount the volume manually by opening the disk image in the ...

klanomath's answer is correct (and should probably be made an answer and not a comment) You already have three partitions on your computer: The EFI partition, the Mac recovery Partition and the main Mac filesystem (usually labeled Macintosh HD). Boot Camp will resize the Mac partition and create a Windows partition, that part is easy as the Boot Camp app ...

The Mac would only have a single partition devoted to OSX (actually there are also hidden partition). You cannot modify the partition while it is in use by OSX. You should restart in recovery mode, and you can then modify the partitions. I have never used Bootcamp, so @Buscar's suggestion may work, but it is easier to use diskutil to make a partition for ...

I have found that using Recovery Partition Creator 3.8 works for me. I use Carbon Copy Cloner to clone the other partitions but Recovery Partition Creator for the Recovery HD partition. It appears to handle the issue of removing partitions after the Recovery HD partition properly, and also works if you have left free space after the volume that the ...

Before you can clone your hard drive with CarbonCopyCloner, you need to create a partition on the drive and format it appropriately for use with your Mac. Most external drives come pre-formatted for use with Windows machines. You can use Disk Utility for this purpose. You'll find Disk Utility under /Applications/Utilities/Disk Utility on your machine. In ...
