There are several possibilities why formatting might go wrong...
1) it was formatted incorrectly. It must be FAT32, directly without partition table. I do not know how Windows decides whether to create a partition table or not; most USB Sticks have a partition table (single partition), but Kobo does not have one.
2) Kobo itself didn't manage to umount the FAT32 before exporting the USB device. This happens for example when you are running mods that block the FAT32 from being umounted, or when connecting USB from within a KEPUB [in this case the umount happens only after some delay]. In this case it results in filesystem corruption which might cause the device to crash, or to be stuck for a long time attempting to run a filesystem recovery.
3) Device was not ejected/umounted properly before pulling the USB cable. At best this causes some missing file, worst it will kick the Kobo into factory reset mode.
Some time ago I had posted a small mod that displays a smiley :-) face if the user partition was umounted correctly, and a :-( face if it was not. Kobo itself does not check at all whether umount worked - it does a lazy umount which just doesn't do anything while the device is still in use.
