I am trying to copy old files from an OS X 10.5.8 to a new external HD. When trying to copy a folder I get the message:
The operation cannot be completed because you do not have sufficient privileges for some of the items.

I've checked the privileges and they seem ok (read & write for me). What is curious is that the folder is created empty on the target drive and I can then copy the contents from inside the original folder to inside the new folder without changing anything else.

This happens with several folders but not all and is making backup a pain. I have to figure out which folder broke the copy, copy its contents to the external disk and then select what hasn't been copied to copy (and eventually stop at some point and repeating the experience)
