Error code -43
Backing up to a blank DVD including personal files,address book, mailboxes, iPhoto events, documents folder, iCal. Got this message :
The operation can’t be completed because one or more required items can’t be found.
(Error code -43)
Could not retrieve file metadata information for "<unable to get file path>" (-43).
What does it mean, how do I find the items that caused it, and how do I fix it ?
