Well that answers my question. Thanks.
I was reading elsewhere on the web that people have been able to access both the internal drive and the SD Card as separate drives on the PC. I'm not sure if those devices had been rooted. Furthermore, my friend insists that he is able to access 2 separate drives on his Incredible.
Basically, after installing rock band, the music (and sounds) were dumped on the SD card, and Winamp sees it as music and labels it as such (Artist, etc.). I was wondering if I moved that music to the internal drive, would Winamp or another player read it differently and not populate it as an artist, album, etc. I wanted to keep the SD card clean for all my personal music.
