in diskutil, I wanted to add another partition to an external fw-hdd, when pressing apply-btn, the tool just never finishes creating the partition, progress bar stays around middle, hdd is working like mad, since over 30mins now! it says 'shrinking the disk' next to the progress bar... what do I do? does aborting DU risk corruption of existing partitions? ayyy! very bad scene since no recent backup available!
