I guess Mac OS X Leopard is treating all the folders I have on my USB hard drive from Windows XP (My Music, My Pictures, My...etc) as locked system directories. Since it did not create them, it seems that I cannot use the "Repair Privileges Utility" to reset permissions back to normal. I want to copy more files into "My Pictures" on my USB hard drive (which acts as a scratch drive for my pictures), rename it Pictures. This volume is a USB hard drive that contains a backup of my roommate's hard drive, thus it would be difficult and time-consuming to copy the files to a new folder on the Mac volume, reformat the USB disk and copy back the files (and I do not know if my roommate would be able to see the new volume on his Windows box). how do I unlock these folders? thank you.
