I am having problems with my Bold 9900, OS 7.0.0250, bundle 1315, and the sdmicro memory cards. Sometimes when I do a battery pull I will get a message that the media card is not installed. Other times when downloading or saving data to the media cards I will lose the connection to the card and have to do a battery pull, It does not make any difference what size card is installed in the phone. Does anyone know what the problem might be and how I can resolve it ? I just ran into the problem of the phone not recognizing my 32gb card, so I removed it, transfered all the files onto my computer. Reinserted the card into the phone and formatted it then copied the files from the computer back onto the card and it works fine now. I am stumped on why the phone will stop recognizing the media card every once in awhile, any insight would be appreciated.
