I think this is an operating system question. I am using OS X 10.3.9. I am going to upgrade as soon as I get a good backup. I have slashes in my file and folder names and it is working fine. However, when I connect my Western Digital MyBook external hard drive, it will not accept the slashes in the file/folder names. I find myself having to rename everything. Is there a solution to this? My old external hard drive did not have this problem. How do I get past it?
