Apple - Support - Discussions - Finding myriad locked files ...

Open the Terminal application.
Type:

cd
and a space. Now drag the hard drive icon on the Desktop to the Terminal window. This will produce the absolute path to the drive at mount point /Volumes. The text should look similar to this:

cd /Volumes/
Press the return key. You are now in the directory that contains the contents of your external drive.
To search for locked files use this command:

find . -flags uchg

If you receive any permissions error then:

sudo find . -flags uchg

Use this command to remove the lock on the files found:

sudo find . -flags uchg -exec chflags nouchg {} \;
