I have an external GSA-E40L SE02.
Burns fine, had a few coasters because too many apps were running.
1 time had a bad verify error.
So all of a sudden the door started to jam, it wouldnt open. It seemed to me that it wasnt a problem internally, but dirt or something sticky on the top of the front panel. I covered the top panel with scotch tape, and voila problem solved!
Does anyone else have this problem?
