Any chance that you had disconnected without safely ejecting first? I believe Kobo uses FAT32 filesystems, which do not like sudden interruptions. I've corrupted my DB and some books a few times from it.
It's also possible that it's just a regular old bad block in the memory and it was touching both the DB and your specific book file. The good news is that it should mark that block as unusable and leave it alone.
