I'm not an apple guy so I'm not sure where to go with this. My son has an external USB drive that had two partitions on it - one HFS+ and one NTFS. He's decided to delete the NTFS partition and wants the whole drive for his Mac filesystem. I fired up gpartd on a stand-alone system and have deleted the NTFS partition, but I can't seem to expand the HFS+ partition to fill the whole disk. Gpartd will let me move it or shrink it but I can't expand it.

I've googled around a bit and it seems like this is a known problem - that HFS+ partitions can't be expanded. Before I give up and use the backup / delete partitions / build new partitions / restore method I thought I'd give it a shot and ask here: anybody know of a tool that will do this in place?
 
Might be able to do this in the Disk Utility app in mac. Make sure the USB drive is connected, then click on the hard drive in Disk Utility and goto the partition tab. From there you can slide the partition that is already on there for OSX to expand to the rest of the free space.
 
Cant use Apple device manager to modify the partitions because the external drive was formatted MBR and device manager refuses to touch it - it will read it but not modify it. Great suggestion if it was GUID/GPT...bummer.

Don't understand why gpartd didn't finish their HFS+ implementation. Frustrating that they will create them, move them, shrink them, but not expand them. Oh well...its still the best all-around partition management tool there is.

In the end I just used brute force. Copied the files onto a spare/bare drive, deleted the HFS+ partition and built a new one the correct size, then copied the files back. Took a few hours but I didn't really care since I was asleep for most of that time.
