hey all i have a 1TB external drive i partitioned and used for time machine (which took 161GB) and now i can't get back the rest of the space? i have tried to look this up and played in disk utility but can't delete or restore the drive to its full capacity. it is still only showing a 161Gb partition. could someone please help me recover the rest of the space? i don't mind deleting or reformatting. would like to just get the space back! thank you.
