I went to change batteries earlier and before i did my sd card was fine, changed the battery and came up SD card damaged. Chose not to reformat and checked the card in my computer and everything was working fine. Put another card in the phone , it worked fine. Replaced card that said damaged and it still says damaged. Any ideas on what may cause this behavior??? BTW I was able to make a backup of the card on my comp after phone said it was damaged. does anything involved with rooting the phone used from the sd card or are all the programs i used saved/ran from the int mem.????
