Can’t Reformat SD Card after rooting your Nook Color? Try this… «

If you can’t reformat your SD card after rooting your Nook Color (with autonooter):

Grab Partition Master (for Windows) from http://partition-tool.com/download.htm. Use it to wipe the SD Card (make sure it’s not your hard drive) then insert into your Nook and let the Nook format (it should ask you or under device settings)

Cheers!
