I have read the other blogs and insured mass data transfer is enabled. I have tried reformatting the SD card. No results. I can see the memory on my BB, but in desktop manager it only sees the 2 meg internal memory. SO, I cannot transfer all my music or pictures. In explorer, I only see the BB as one drive with folders for applications, etc. No SD card.
I don't know about mass data transfer, but enable " Mass Storage Mode" on your Storm2? The software version on your Storm2 is v5? The media card is 16 gigabyte, not sure if I spelled "gigabyte" correctly.
