TP2 intermittently reading microsd card?

[zillanilla]

Whenever I listen to MP3s off my card for an extended period of time (extended could be 10 songs or 2 hours depending on the day), the micro sd card simply disappears. My Sprint TP2 won't recognize it until either I reboot or take out the card and put it back in. Just writing to see if anyone else experiences this issue. I searched for similar threads and couldn't find one, so if this is a repost then please point me in the right direction. Thanks in advance!
