As it it, I am not going to fight it. I plugged it back in and will just wait it out so that I can configure my device after it is finished reading it. The last time I did this, I just had to tell it to only look at the BOOKS folder (and to set all uploads to go to the BOOKS folder)
This is just another pain of having to reformat my computer this past weekend
BTW...I tried your advice about removing the card. It is set up such that it is included as part of the internal memory, and the tablet does not want to operate without it.
