OK! So I bought a new micro SD card. The same one shown in the top left of the pics of good cards for B2W shown above in the reply by estore009. Formatted it to FAT32 w/ MiniAide. Put it in the B2W. On power-up I get the same "wrong cluster size" message shown back when I put the fake card into the B2W. It also says "Format Card". So I did--in the B2W. Twice. No help--each time I turn power ON, the same error message displays. Any thoughts for actually solving this? I'm testing the new card w/ H2testw now...
Thanks again, Chris
