Battery was very low, then recharged but not used for several days.
I loaded a couple maps and songs onto existing 1GB SD card.
Now does not recognize parts of SD card.
Plays the music without problem.
When I attempt to open Epocrates drug program message says parts are missing, sync again. For a time, it said card was locked, but card still played music.
Maps give me an error code.
I have uninstalled and reinstalled maps, sync feature, music, drug program to no avail. I've used two different SD cards- 1GB and a 512.
Thanks.
