SanDisk 2GB MicroSD Card with SD & MiniSD Adapters I purchased one of these for use with Q9m. If I used the SanDisk Micro to Mini SD adapter I could never get it to work in my phone. It either did not detect the card or it would lock up the phone where nothing worked until the card was removed. I performed 2 tests to see if it was the card. I put the card in the Micro to regular SD adapter and plugged it into 2 different digital cameras. Everything worked as expected. I then took the card and plugged it into the Micro to Mini adapter that came with Q9m. The card worked perfect. My conclusion was the Micro to Mini adapter was hosed. I returned the card yesterday, which was purchased about a week before Christmas, and got a replacement. After messing around with the replacement it had exactly the same issues. The SanDisk Micro to Mini SD adapter was bad. Comparing the SanDisk adapter to the one that came with my Q9m there is no comparison. The SanDisk adapter is cheaper plastic and no where near as quality a unit. I returned the SanDisk and ended up getting a regular 2 GB Mini SD card. I bought the SanDisk to start with because it was on sale cheaper than the Mini SD card of the same capacity. I plugged the new card in the phone and it worked fine. Maybe I got a couple of bad ones but I would suspect the adapter if you are using the San Disk one and your phone is having problems with locking up, reading the cards memory and randomly telling you the card can't be read and needs to be formatted.
