This question already has an answer here:

I have an external USB drive, which I've partitioned into separate FAT32 ("MOVIES") and OSX ("TIME_MACHINE") partitions:

enter image description here

I now wish to remove the FAT32 partition and just use the OSX partition.

Aside from reformating the disk with a single OSX partition, is it possible to:

  • remove/erase the FAT32 partition, then
  • expand the OSX partition to take up the entire drive

without losing the contents of the OSX partition?

Disk Utility can't do it, but iPartition can - http://www.coriolis-systems.com/iPartition.php

Tested on both GUID & MBR formatted drives.
