I'm trying to secure-empty-trash a large backup disk image, about 275 gigs. During the process I had put the computer to sleep a couple times. After that, it seemed to be making no progress. I tried to stop the process so I could try again, and now it says "Emptying the Trash... Stopping..." and has said that for hours with no apparent progress on the status bar. Is there anything I can do get it to finish the process, or to actually stop so I can try again?
