sorry for myMy question is in fact related to OS X, however I'm using Linux tools to resolve my problem.
I'm trying to delete all the partitions on my SSD drive and create new GUID (HFS+) partition table. Native Disk Utility is unable to eject disk to re-partition it. From the terminal, which is included in the OS X install, I've run diskutil listran diskutil and here is the output:

diskutil unmountDisk force /dev/disk0...12 also can't unmount disks.
I've started Ubuntu 12.10 from USB, tried to delete all partitions with GParted ( exceptexcept the recovery partition),; it seems to be ok, howeverbut the disk is still unavailable for creating partitions with Apple Disk Utility. And certainly I can't create HFS+ partitions in GParted, cause I don't have hfsprogshfsprogs installed, and there is no way to install 'cause I don't have Internet connection ( ubuntuUbuntu can't work with Mac Book Retina wi-fiwifi adapters).
So, the main question is what are these 12 partitions and how to delete them and create one HFS+ partitions? thanks!
