Just need some help with resizing a partition.
I had a 750GB USB external drive which I had 400gb for time machine and the rest for storage of media files. I've recently brought a time capsule so have the storage area backed up on this now, so no longer need the 400gb for time machine.
I want to extend the storage area to fill the drive so I removed the 400gb partition but I can't now extend the other one.
See the attached screenshot, I need to extend the IcyBox partition so how would I do this? I've tried typing in the new size but no joy.
