TESTING: SuperDuper problems copying some data

[dnanian]

I don't think you can say they're good files, Steve: something's clearly wacky, since they can't be copied with SuperDuper! or ditto (and probably not with cp or other Unix-level tools either).

I did see that Disk Warrior says the catalog is "fine" (though you didn't indicate that you had rebuilt), but maybe fsck does the rebuild differently and might work around the issue.

Try copying a file that won't copy with SD! with ditto and cp, in Terminal (making sure to preserve the resource fork with ditto). Do they work?
