I posted a help thread here in the Nook developer's corner earlier and was told I might have better luck with the xda deveopers forum, so I posted for help there and was told to simply repartition my card using partition magic, which isn't free. Except, when I loaded the card into my laptop's SD card reader, I got a prompt saying that the card was unformatted and would I like to format it now? I know formatting would wipe all the data (which I couldn't access anyway since the cardreader wouldn't read the card), so I decided to try a data recovery using Easeus partition manager (couldn't do an image backup because of the inability to read the card's contents).
The data seems to have been recovered completely, but I don't know how to return the data to the card in the same state it was before I did the reformat. Also, I tried repartitioning the SD card after recovering the data and reformatting, but Minitool Partition Wizard won't create the partitions that I select, and now when I reinsert the SD card into the Nook it won't recognize the card either.

I had a similar problem with one of my SD cards after I burned and used the card with one of the rooting/recovery tools: my Nook does not recognize the card, and the card cannot be repartitioned (EASUS and MiniTool would go through the motion but fail to create new partition).
FWIW through some trials/errors I was able to recover the card by first reformatting it with Windows (while in Windows Explorer right click on the SDcard then select "Format"), then reformatting with SD Formatter (
https://www.sdcard.org/downloads/formatter_3/)
with the Full OverWrite option.
From this experience I now have a few small cards (2GB-4GB, hence relatively inexpensive) set aside for backup/flashing/rooting uses.

Hope someone here can help me. If the worst case scenario happens I won't be able to return my Nook to stock state either, because the backup image was made using NookManager, and all the data is probably buried somewhere in the data recovery I made earlier which I don't know how to re-incorporate into the card.

Assuming your Nook is a non-Glow Simple Touch, if you ever need go back to stock ROM config you might consider using the TouchFormatter tool posted at
http://forum.xda-developers.com/show....php?t=1475613 which should restore your NST to factory fresh state with FW v1.1 (from which you can upgrade to the current FW version using standard BN FW update process). I had used it successfully with my NST after a borked rooting operation.
