Can't delete files from Trash I'm trying to empty my trash, and it seems that I having some problem with encoding:

MacKassner:501 kassner$ rm -Rf t/t/
rm: t/t//t: Directory not empty
rm: t/t/: Directory not empty


Ok then, let's see what's inside:

MacKassner:t kassner$ pwd
/Volumes/DATA/.Trashes/501/t/t/t
MacKassner:t kassner$ ls -la
ls: 07 The Kids (feat. Janelle Monáe).mp3: No such file or directory
total 128
drwxrwxrwx  1 kassner  staff  32768 Jan  7 10:42 .
drwxrwxrwx  1 kassner  staff  32768 Feb  4 18:12 ..


It seems a problem with the special char on that file. I can't empty trash using Finder either (even securely).

EDIT: StackExchange changes a litte bit the exhibition of the special character. Here's a screenshot:
The quick and dirty way to trash a folder is to move another folder with the same name into the existing folder. It looks like you have a folder t which might be amenable to making a new folder on the data drive and name it identically to the folder you wish to nuke and then trashing the "new" t folder.

If that doesn't work, you should be able to open a finder window and attempt to rename the problematic file. See http://support.apple.com/en-us/HT201583 for details.

Lastly, if nothing works, consider posting what format the /Volumes/DATA is via diskutil list and sudo ls -laOR /Volumes/DATA/.Trashes/
