Just a hunch, but did you reformat your card to the wrong type?

It sounds like your partitions might be backwards. The SD card's partitions must begin with the "data" (FAT32) section, followed by the "system" (ext2), and ended with the "swap" partition. The ext2 partition, from my understanding, is where apps will go. The FAT32 partition is where all the "clutter" such as music, will go. Since you've already partitioned a Prevail SD Card, no need to mention the mess to get to that point; I'll just mention to use the following code to check your existing partitions:

adb shell reboot recovery
adb shell
parted /dev/block/mmcblk0
print

Start by doing a little bit of math:

total sd card size = A
A - swap area (0 is fine for a phone) = B
B - ext2 area (512 to 1024 should be good) = C

With those numbers, the partitions (info from the print command) should look like the following:

0 to C = FAT32
C to B = ext2
B to A = swap
