I'm stumped. I have one (1!) user who keeps getting a -47 error when
FSCopyObjectSync is called to duplicate a file on an external
volume. The volume is formatted HFS+journaled, it's a Lacie 500GB
connected is USB.
I had them do an lsof immediately after this happened; none of the
files being copied were open.
Anyone have any idea why FSCopyObjectSync would return -47? Could
their be something wrong with their drive/system?

If you can get them to send you an fs_usage log (with "-w"), you can
look for the equivalent errno-style error (EBUSY, 16).
Here's another idea...
The copy engine also takes a "reservation" on objects while copying so
that an item being written to by one instance of the copy engine
cannot be copied by another instance while it is incomplete. Could a
Finder copy or Time Machine backup be in progress on the user's system
when your code gets this error?
