That often occurs when you don't unmount the filesystem and give it  
time to flush. The standard "magic incantation" is:

umount <filesystem>
sync
sync
sync

This has to be done for both the main memory and the memory card, but  
you can unmount both and then do the sync commands.

It also pays to check and see if there is an indicator the file system  
is still in use. The original Kindle has a set of four blocks that  
flash on and off while there is USB activity. The nook once the  
unmount is finished goes from a "USB disk" screen back to where it was  
before you connected the USB port.

The eVrit may have a similar function.

You can also avoid the problem by using the sync mount option.
