Playing Duplicate music files, EXT.card not recognized in winamp

I have a 2.0GB FUZE, and when I plug it in to add/remove mp3 songs to the library in winamp, Under “PORTABLES”, it shows both drives -

   *(no image)      0 MiB (0%)

   *(no image)      0 MiB (0%)

USB DRIVE G:        1.83 GiB (1%)   Internal Drive  2.0GB

USB DRIVE G:        1.83 GiB (1%)

USB DRIVE H:        7.61 GiB (2%)   External Drive 8.0GB

USB DRIVE H:        7.61 GiB (2%) 

When I click on the top drive *(no image) it shows All (0 artists, 193 without artist) 1 album

When I click on the bottom drive *(no image) it shows All (0 artists)

What causes this to duplicate the songs?  I play one song, then the same song plays,but in the winamp library ,it only shows one artist/album at a time?

the songs are probably being put in both the internal memory and external memory, and showing up as two on your fuze
