I bought a Muvo2 to use the microdrive in my camera. I replaced it with a 1GB microdrive I had previously used.
I used it to run, walk to work, and was probably way too rough with it. It no longer works and I need a new card. It makes bad noises whenever I try to turn it on. It could just be that I had previously damaged the drive (I had used it in my camera for >1 year) but I'm sure that the 2 months it was in the Muvo2 was what did it in.
