Format an M2 Sony Memory Card
Sony M2 memory cards are a fraction of the size of other memory cards and are necessary if using certain Sony products. Just like with any memory card, they are fragile and susceptible to errors after constant use. Sometimes you need to just wipe off the old information and do a clean install. The Sony product you use the M2 memory card with is your best bet for formatting, though a computer format can be used as a backup plan.
Instructions
1. Save any information off the M2 memory card before proceeding. Formatting a card will permanently erase all the information off of it. To save files to a computer, you will need a Sony Memory Stick Duo adapter. The M2 memory card fits in the adaptor, which then can be inserted into a media reader. If the computer has a media reader, you can plug it in directly. If not, you will need a USB media reader and plug it into the USB port. Once inserted into the computer you can access the M2 memory card like a hard drive and save any files.
2. Determine the device you wish to use for the M2 memory card. Different devices have different ideal formats.
3. Insert the memory card into your device (Camera, PSP, etc.). Go to the option menu and find the option labeled "format." All Sony devices should be able to format the memory card themselves. If you have trouble finding the menu option, look in the device's manual for the exact location.
4. Choose to format M2 memory card. You will be asked if you are sure if you want to proceed; select "yes" or "ok." Give the device ample time to complete the format.
5. If the memory card cannot be read by your device and thus is not able to be formatted, then you can format using your computer. Be advised that you only want to do this to get the M2 to be readable again. Plug in the M2 card to your computer and right-click on the drive. Scroll down and select "Format." Choose the Fat32 option and select "start" at the pop-up screen.
6. Remove the M2 card from the computer and reinsert the formatted M2 card into your Sony device. Format it again.
