[Q] HTC Rezound, after mounting SDcard, media on sdcard not showing up topic

Hi guys. i took the sdcard out and loaded more mp3's into it as i have in the past. i put it back into the Rezound and turned the phone on. then i "mount sd card" in settings. but the music and the pictures on the sdcard are not appearing, even though the phone shows it being mounted with the space available.

i've double checked and the data on the sdcard is good. it was working fine until i pulled it out and uploaded more mp3's on it. now the phone knows there is a sdcard in it, but the music app and camera/gallery apps are only showing files from the internal memory.

phone is rooted, i've frozen some apps and stuff with titanium backup, but i haven't changed anything recently, and it was working fine until now.

THANK YOU in advance!!!
