As is beauty, "full" is in the eye of the beholder. The Kobo firmware tries to reserve some space to make sure there is room to rewrite the database, generate covers and other things. Hence, it will report is full while there is still space available. From memory, this is somewhere in the 50MB-100MB range. But, It is definitely less than 298MB. Obviously something else was going on, but I think it is to late to find out. If I had had it in my hands when this happened, I might be able to tell what happened, but I think it's to late now.
