Folks, within Terminal, I am unable to chown, chmod, rm -Rf, or shred -vfuz to a file. I can however "echo xyz > fileName. I can create, delete or alter other files. My objective is to delete the file and its parent directories but it will not vanquish. Background, the drive is a 750G USB from a Mac 10.6 used for backups of iPhoto and therein lies the bigger problem. I am using Ubuntu 12.03 as a file/media/print server on a cute little MSI netBook . Tis not an option to reFormat the drive. Thanks to all and may someone have the answer, please.

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.
Given that you don't own the files or directories, it is likely that the root user or adm group can. Try to delete the files with sudo rm -rf /directoryname.
