The problem turned out to be the PMBR. My first attempt was to copy sector 0 off a GPT formatted memory stick. Examined that with fdisk and it had partition of type EE, but start and end cylinders were the same. I edited partition 1 and accepted defaults. fdisk on mac will report "can't get exclusive access to write sector back, reboot required" It ...

I tried everything from apple.stackexchange and other blogs but none worked. But this method worked like charm: Make a bootable Windows USB using bootcamp. Do not partition or download support files. Restart your comp holding "option" key. Open Windows partition and keep clicking next until you have to choose to format a disk. Choose the block with the ...

I recieved "Partition map check failed because no slices were found.” from Disk Utility but perhaps for different reasons. I had to reMOUNT (either it's a "right-click" or a button) the partition from Disk Utility and then Repair the partition. Then it worked - heart attack / data loss averted.

You could see about getting a quote from a data recovery team to attempt to reverse engineer your situation. Since you are fairly certain that the key is 12 characters long, that significantly reduces the number of passphrase that must be attempted to unlock the volume. Also, paying a professional to do this means you are only renting the equipment and/or ...

I had the same problem as you, and i searched all the forums and i found that if you turn off FileVault it should work.

Though the following should be valid for non-encrypted volumes and unlocked encrypted volumes, it doesn't help much because the main volume here is encrypted and locked. So skip to FileVault2-encrypted volumes Non-encrypted volumes Almost no free space on your start volume is a problem. At least 10% free space are recommended. It's indeed possible to ...

Actually you have a CoreStorage Logical Volume Group on your physical disk named "Macintosh HD" containing a Logical Volume also named "Macintosh HD". The latter is the volume usually visible on your desktop (depending on your Finder settings). The Logical Volume Group already extends across your whole physical disk except an invisible EFI partition (200 MB) ...

The original post mentions that SSDs have a 1000-2000 cycle limit, which over-simplifies the problem. Individual cells in an SSD may have such a limit, but the SSD implements many different solutions: from over-provisioning and write-levelling to Sandforce's proprietary collection of de-duplication, compression, and data differencing techniques, which it ...

My first thought would be that it is a permissions error of some kind… Either the Drive is formatted as NTFS or ExtFS etc The System doesn't have write permissions to the device itself For the first, the simplest, if not cheapest solution would be something like Paragon NTFS or ExtFS or Tuxera NTFS If it is a pure permissions/ownership issue, then for ...

I wouldn't suggest continuing to use an external drive for your MBP, apart from anything else it's just not practical. It seems like your internal drive has or is just about to fail. Have you/can you check it's SMART status from disk utility? Either way, I would suggest not worrying about trying to verify or repair it - just try and get your important ...

You can't move the start block (=380677208 for LVG2 or "Macintosh HD 2" in your case) of a CoreStorage Volume (Group) non-destructively. The same is valid for non-CoreStorage partitions with on-board tools. AFAIK for the latter only iPartition and gparted work. Therefore you can't easily reclaim empty space with a lower start block and an arbitrary size and ...

My SeaGate GoFlex was working great, but then mysteriously disappeared from Finder and couldn‘t be repaired in “Disk Utility.” What finally worked, after opening up “Activity Monitor” application, I noticed there was a “Seagate Utility Gauge” process running. After Googling that, I noticed other people were uninstalling it. ...

If you're asking what I think you are, simply click and drag the bottom right hand corner of the blue 'Macintosh HD' partition downwards to reclaim the space you've free'd by removing the Ubuntu partition. You don't need to reinstall OS X.

As for the Yosemite bootable disk, it should be possible to make one from the Yosemite installer app - Be sure that you have downloaded it, not installed it. I think 8Gb should be enough actually. For the stubborn Partition, I like to use Linux for this. Any Linux Distro should be suitable, because it has GParted most of the time. Format the stubborn ...

If the machine still boots, go to the App store and "purchase" Yosemite (its free). Now boot the machine holding COMMAND R and boot to internet recovery. If you see a poorly animated spinning globe instead of an Apple logo then you are on the right track. Now you have can reformat the whole drive and do a clean install of Yosemite.

Can you select the free space partition then hit the minus (-) button to delete it? You'll probably need to try that, then see if you can drag the border of the main partition to resize, then hit the plus (+) to create a new partition. Nothing can use the free partition, so it won't hurt to try deleting it.

Orphaned inodes, are common, but they do normally get cleaned, latest after a restart. This is not a bug, it's the journaling clearing up a normal situation. An "orphaned" inode in this context is one which has been explicitly deleted, but which was still open by some process when it was deleted. The file vanishes completely from the directory ...

The Recovery Partition is created during OS X installation. Normally that partition is hidden unless you are using the Debug mode in Disk Utility to show all partitions. In other words, it should not be showing in your system as it is. Turn off the show all partitions (in Debug menu), and check. If it is still there back it up (for safety) then delete ...

Well, I have another solution; hope it would work fine. Backup Windows data (bootcamp) firstly. Use Bootcamp utility to delete the existing Windows partition. Once you delete it, recreate new Windows partition with Bootcamp a little larger as you desire. Then reinstall Windows.

Update 3) (I deleted Update 2) I am glad, klanomath posted his answer. For me post, I would have to plagiarize his work. Deuce55 you can ignore this update.

If I remember correctly, if the partition type is GUID then you should be able to resize by just dragging the line that divides your partitions. You might need to delete the empty space partition first by clicking on it and hitting the '-' button, but then you should be able to drag the active partition to whatever size you want. Afterwards, you can '+' the ...
