Samsung Blackjack Troubleshooting

I have a Samsung Blackjack 2 (Windows Mobile 6.1). The Micro SD card is made by SanDisk. I turned the phone earlier in the day, but when I turned back, micro sd does not work. never happened to me before. Someone is there anyway I can solve this problem or some type of troubleshooting process I can go? and I was listening to music on Windows Mobile 6.1 if it could not be the reason. does the micro sd card have some type of lock button secret that I do not know. is really smaller too, if you did not know.

I've never heard of it, try removing the micro SD card, and hand in. Otherwise call customer service!

OK try
1) remove micro sd
2) Put your phone
3 micro insert) sd
4) Turn on your phone

If this does not work, try on someone elses phone sd
or if you have a PC or know someone with a PC card reader Multi plug into your PC if you can access it then.
