Sansa Express 1gig w/2gig FM recording issue

Hi All,


I have a Sansa Express 1 gig with an additional 2 gig microsd card installed. I have a need to record off the FM radio for more than 2 hours, but it stops recording at about 2 hours. I have 01.01.12a firmware, still had 52meg of internal memory, and 1870meg SD memory free. According to one of the writeups, 01.01.12 states " 2-hour limitation on recording has been removed; it will record until the memory is full". Is that for “internal” memory only, or does it need to be formatted differently? Anyone know if 01.01.12 and 01.01.12a are the same as respects this limitation?
