Diff Detail
Event TimelineComment Actions This is likely a good change. 3a/0 is definitely right, not sure about the other two. Comment Actions This change is about semantics. An ejected CD, empty tray, or missing tape is a transient media state, not a fatal device condition. Marking it as SS_FAIL better reflects that distinction. Only 3A/00 was tested with an SD reader. i can follow up with additional testing on optical media and can amend or reopen a diff if needed.
