Argh. I just tried to back up my home directory folder to a DVD. When the burn was nearing completion, it aborted because Finder “cannot find data fork of file <unable to locate file path>”. Got that? Four gigabytes of files can’t be archived because one of them — which may not really exist, for all I can tell — is corrupt. And why didn’t this error message show up during the “Preparing data” phase, to save me from wasting a blank?

Later: It occurred to me that this could have happened because a temporary file was deleted between the preparation and the burn. So I closed all applications and tried again; no luck. Then I noticed on the packaging that these Memorex 8X blanks apparently cannot be burned properly by my 2X drive. (sigh)
