CorruptError: CorruptError: database disk image is malformed
Looking at where the error occurred in the driver, I'm surprised you didn't get an error when calibre was getting the book list from the device. That could mean the corrupted part of the database is an index. And compressing the database might fix it. My Kobo Utilities plugin has a function to do this. I'm not certain it will work, but you will be in no worse position than you currently are.

If this doesn't work, then JSWolf's and PeterT's suggestions are the way to recover.
