OK. So error checking came up with nothing. I tried reformatting the internal storage using the default settings Fat32 and allocation size of 4096. The process failed on 4096, 2048 & 1024. I fianlly dropped the allocation size to 512, the reformat was successful and I am reading from the nook like a champ. I'm not sure of the cause but glad I found the fix. Thanks for the help.
