Resolved Hard drive issues. HD won't reformat or repair permissions

[Redsandx619]

Hello,

I've googled and read several how to's and still no luck. Hopefully you guys can help me out. I originally had Windows 8 installed via bootcamp and had to do a work around to get it installed before Apple patched HDs over 2TB.

So, I would like to completely reformat my HD. I want to do a clean install of Mavericks. This is where I'm having issues.
I boot up Disk Utility and the Hard Drive is showing that its full and has 0 bytes available.

I also have a Logical Partition I can not erase or mount.

Here are the two Partitions, I'm unable to erase or merge them.

I ran "Verify Disk" on the hard drive, all showed up green and "OK"

After the hard drive showed up as "OK" I tried to mount and erase the drive, here is the message I received:

Here is the erase failed message I also received

Information from the "Info" button at the top, hope this helps for something:

After the error messages, I tried to verify the Hard Drive, I get a failed message:

Here is more information on the hard drive:

What I thought was strange, is that I'm currently working off of the "Macintosh HD" as that is what I have the OSX installed on. Although, the "Startup Disk" is showing up as "Macintosh_HD". This name doesn't appear in the disk utility.

Here is more information from the hard drive

I ran TechTool Pro 7 to try and repair the Disk Permissions, the open was greyed out.

I was also unable to rebuild the hard drive as that option was greyed out as well

Any help would be greatly appreciated. I'm just looking to completely erase my hard drive and start fresh.

The hard drive is a member of a Core Storage Logical Volume Group, which is why you are having such trouble managing it.

To remove the logical volume group and re-initialize the physical drive, enter this is the Terminal:

diskutil cs list

You should see a tree-view of the Core Storage Logical Volume Group as well as the participating Logical Volumes. Note the UUID of each Logical Volume, and remove them with:

diskutil cs deleteVolume <UUID>

where <UUID> is the UUID of a logical volume.

After each logical volume is removed, you can remove the entire group with:

disktuil cs delete <UUID>

where <UUID> is the UUID of the logical volume group. This should trigger a re-initialization of the entire disk.

Thank you for the reply ElectricSheep! I will give this a shot when I get home, will post my results!

I would also boot off the USB drive and use Disk Utility from there instead of the HD.

I'm currently running Mountain Lion via my USB drive, same result.

That's strange. Usually that will let you erase.

Give Disk Warrior a try.

Perhaps whatever you did to enable Windows on 3TB drive caused a problem?

I just solved the issue this morning. I tried Tech Tool Pro 7 and DiskWarrior, no luck either.

I used Gparted.
http://gparted.sourceforge.net/

I created a bootable disk and was able to completely erase each partition with zero problems. It was pretty awesome.

Once erased, I was able to go back in and delete the Volume and Logical Group. Then just reformatted using the Mac Disk Utility.

Thanks for all the help guys!
