I decided to streamline the partitioning scheme as much as possible. I deleted my leading, unused partition, but this still didn't make it go. Somehow the partition type of the EFI partition had gotten changed, so I decided to fix that. There doesn't seem to be any obvious way to do this from within OSX, so I rebooted off of a live Ubuntu boot image on a ...

Read somewhere about trying to click Repair several times until it worked. It took a while until it took it and I was able to recover the disk , backed it up and format it.

As far as I know, the recovery partition is always created with the exact size of 650MB (1269536 sectors), regardless of hardware and OS X version. As disk utility will refuse to copy just the recovery partition, the next obvious option is to dd the stock 10.9 recovery from another machine/disk with 10.9. How to go about this largely depends on what ...

exFAT is not optimal for your situation probably, but unfortunately there isn't really a no-brainer solution for using an external drive frequently with both OS X and Windows, reading/writing large files, and with really low risk of data loss. exFAT is not a journalled file system, so there is higher probability of data loss than with NTFS or HFS+. exFAT ...

This situation has been a common experience for those who first installed Yosemite on a secondary volume to try it out before committing to using it full time. It has also been noted by those who consolidated former Boot Camp volumes (via repartitioning) into free space on the startup volume. I assure you the solution is simple and non-destructive, with ...

Start from the original disk, open disk utility and reformat the disk. Then reinstall.

Sory to say that it looks like you had a major disk crash of some sort. If Disk Utility can't fix it and Diskwarrior also can't repair it it is likely that some or all of your data is corrupted/damaged or just plain gone. The file names you mention "file000001.png" and the like are indicative of some serious issue and the files on your drive have been ...

What you currently are doing is correct. In this case it is a good idea to quickly restore EVERY file you can find through a file recovery program. You are very lucky that the data was not completely erased. DO NOT WRITE anything else to the disc, as you risk loosing more data. In my personal experience restoring lost data, I usually: 1. Backup ALL Data I ...

To recover the Boot Camp partition (Source): Enter: sudo gpt -vv -r show /dev/disk0 to get some partition informations. Download and install GPT Fdisk (aka gdisk). Download and install TestDisk. Open TestDisk and make a deep search for your Windows partition. Leave your Testdisk display and start a new Terminal Window. You need to use the following ...

If you insert the USB drive, launch Disk utility and select the USB drive on the left side of the Disk Utility window you should now be able to operate on it. Personally I would select Partition and then the number of partitions you want. Then apply it. That should do it

I suggest you use Apple Mac's Disk Utility, select the disk or volume in the LH column that you wish to clear, specify a format and name and click on Erase. Also select Security Options if you wish to prevent any recovery of previously deleted files.

Why Disk Utility does it this way is a good question, but when both the drive and volume show like this, its a CoreStorage volume. These terminal commands should put it back to the old way if it isn't encrypted: diskutil cs list - find the "Logical Volume" (not Group) and copy the long "number" at the end of the line (it looks like this: ...

it is very easy to solve, do not need to boot or restar. I had same problem before. remember everything can be done with terminal. you can use a command in terminal to reformat the partition to the default format to MAC os.I am sorry I cannot remember it. Then you can do anything with this new generated partition using disk utility.

The easiest way is to create a new partition from your startup partition. You will notice that the new partition also gets the space of the free partition you want to get hold of. Then delete the new partition. And viola! you get the space of the whole physical drive again. all in one partition!

Depending on how old the original MBA is compared to the new one, you probably won't be able to do a bare metal restore. What you can do, is do a fresh OS install (if not done already) and "Migrate Your Settings" from the Time Machine Backup.

You can't do what you are asking, per se. What you would have to do is create new partition "above" your existing partition, copy the data there, kill the partition below, then expand the partition with the data into the newly created free space. You can do this with Disk Utility. OS X Daily has a really good write up on it (limited on how to resize the ...

I don't think Disk Utility will let you "burn" an ISO to a hard drive. It might let you "restore" the content to the drive. Select the ISO image in the right-hand side, then drag and drop the hard drive into the "Destination" field and click "Restore". I don't have a device here to test, but that might work. Normally people "burn" ISO images to CDs or ...

First, as an FYI, you only need to boot into the recovery partition to repair permissions when you are trying to repair permissions on your computer's boot drive. To do it for any other drive, simple select it in Disk Utility and click the Repair Disk Permissions button. This may solve your problem, so try that first. After that, the simplest solution is to ...

Disk Utility will not fix every conceivable disk corruption issue. For that you need third-party apps. I use Diskwarrior and have also had success with Drive Genius. However there is one way to do this without buying a disk repair utility. Back up your hard drive, partition/reformat it, reinstall the OS and restore your backup. Yeah it's more complicated ...

It seems that after a little more research, I was able to recover my issue with a more aggressive fsck_hfs -drfs /dev/disk0s2 call.

Note that i made a wrong action by globally changing permissions in the var folder. After reinstalling system, still had problems to open dmg files The DiskUtility announced the following issues : Permissions differ on "private/var/db/ConfigurationProfiles"; should be drwxr-xr-x ; they are drwsr-s--T Warning: SUID file ...

If you have two Machintosh HDs together, choose the second (indented) one. You may need to unlock it via the context menu. Then tell Disk Utility to create an image of the volume directly. In Disk Utility with the Macintosh HD volume selected, use New disk image on the toolbar or select New > Disk Image from "Macintosh HD" from the File menu. Bear in mind ...

The solution that works on both OS 10.11 El Capitan and on OS 10.10 Yosemite is: Open up Disk Utility Select the actual drive, which is the lower part that will most likely be greyed out: Then go to Erase Select MAC OS EXTENDED (Journaled, Encrypted) It's important to select Encrypted Then enter a password and wait.(It will run without a problem ) Then you ...

When updating to Yosemite you will want to make sure that you are at least running 10.6.8. Running the early versions of 10.6 when updating to Yosemite, will cause errors. You will also want to make sure that the TRIM has been disabled. Please take a look at this OWC Blog post for instructions: ...
