USB Memory Stick - Hidden Files
When I plug in my USB memory stick, even though it shows empty, there are hidden file son it which have not been deleted. The only way I can see these files to delete them is to plug it into a pc which shows all the files so I can delete. But how can I clear the stick on my mac? I have tried the Disk Utilty to no avail.
MacBook, Mac OS X (10.4.10)
