Cannot empty trash from ext. hd.
Hello beautiful people,
I tried to delete a copy of a time machine backup from my external hard drive. But what had happened was- my laptop ran out of battery during the deletion process. The total size of the TM backup folder is ~255GB. I have gotten some free space back-- about 147GB, but not my full 255GB.
Everytime I empty the trash, it prompts me to remove unlocked items, or all. I choose all, but the backup remains in the Trash.
How can I successfully empty my trash and recover my 255GB due to my mishap?
MacBook Pro, OS X Mountain Lion (10.8.4)
