Hello,
Everytime i insert my sd memory card i get an error message saying i need to format it before i can use it, but i am able to us it when i put it back into my phone with no problem please help?
It could be that your computer's card reader is not able to handle the capacity of the card. SD card capacity has been growing steadily and many older readers cannot handle the newer High Capacity or eXtended Capacity media that's out there now.
No problem, you can recover lost data from memory card with freeware recuva. This is a professional program that can recover data after deeply scanning your memory card to look for lost data.
But you had better have stopped using the memory card. Because, once the data were overwritten by new ones,they are gone for good. For your convenience, you can download the software from here: http://www.tomshardware.com/forum/280846-32-will-recover-hard-drive
