I had a problem where I loaded an MP3 Gain program with a 4G fuse and an 8G card inserted. I had 2G left of the memory card before MP3 Gain. After that program, I had 177 MB (probably thanks to the WiMP interface). Formating then removing the SDHC card and with a firmware update, I ended up with 1.7G out of the base 4G. After I fill the base 4G, will the 8G card add the additional memory correctly (as the 2nd “drive”) upon re-insertion?
