I have an external HDD connected to a Lion iMac (though I can use my Mountain Lion Air if it will make the process simpler) that was split right down the middle with two partitions. The first was clear and the second was FileVault 2'd and was used as a Time Machine. My intent is to end up with one FileVault 2 partition spanning the entire drive.
I have already moved the data from the clear partition to the second and removed it, and I have already decrypted the FileVault 2 partition so that it can be resized. However, Disk Utility will only let me resize the second partition at its end, not move its top end up. (Once resized to fill the disk, I intend to re-encrypt the partition.) It seems I may have to move the second partition to the top of the drive first.
How would I go about expanding this partition to fill the entire drive? I think there is enough space that I could effectively copy the second partition into the free space at the top.
diskutil list output (though this doesn't appear to show where the empty space is):
/dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *2.0 TB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Time Machine 999.9 GB disk2s2 3: Apple_Boot Boot OS X 134.2 MB disk2s3
diskutil cs list shows nothing for the disk in question. It used to, before I decrypted the FileVault volume. It's my understanding that the disk was un-CoreStoraged (if that makes any sense—forgive me, I'm learning this stuff on the fly) after decryption.
