Exact message: There appears to be a problem with your eReaders internal storage. To fix the problem it is reccommended that you reset your device to factory defaults and follow the set up instructions to restore your books and account information.
Options: cancel, factory reset
The first time this message appeared I did the factory reset and the device froze. I couldn't turn it on/off, and the pin reset didn't work so I had to go replace it at my local store.
I don't want this to happen again so I've been pressing cancel.
I don't use Calibre and I always eject the device from the Kobo desktop app.

What could have caused this to happen? How do I fix it? Do I just have to wait for Kobo to release a new version (2.0.0)?
