i have only one optical reading device which is a samsung 40x10x40 cdrw model SW-240B. everytime i insert a cd (either legal or burnt) it doesnt read it. its inserted and all but when i double click the cd icon in my computer it tells me to insert a cd in the drive. then, i open the cdrw, close it again with the cd still in it and it reads it. whats up with that? loose ide cable maybe? software prob??
