I use a Sansa Fuze 8GB with an microSD Card. Both “devices” are full of music. After I synchronise the player with MJ15 the data base will be updated.
It is normal, that this process takes 5 minutes and longer?!? Without the microSD Card, it takes only a few seconds!
Which is the “best” format oif the microSD Card (FAT / FAT32 / cluster etcpp) ?
