I like to back up my music cds to my 'Music' directory for playing directly from my computer. This has always worked fine until suddenly--all the 'folders' are empty. As if I'd shift-deleted every song individually, leaving only the empty 'folders'. Nothing in Trash, nothing in root Trash.
Thanks in advance.
p.s. I've just checked my most recent full backup and the files are missing there, too--so, apparently, this has been going on for a while. My external hard drive seems unaffected.
