Now that you say that the goal is to remove the file, I would try deleting it by inode, bypassing the filename altogether. A combination of ls & find will probably do the job. Web searches should turn up a useful recipe. If that failed, I would cheerfully ignore it in the knowledge that the drive is going to die some day. I'm mildly curious as to how it got to Trash (since files don't tend to originate there, so it was moved there by something). Not curious enough to experiment though. I have a list of quixotic tasks I'm working on already.
