Help Preparing SD Card, Checking for errors

Hi
I've had the above message on my SF Phone for a couple of days and it keeps switching itself off and on. Has my phone come to the end of its life or can I fix this? I haven't done anything different with my phone recently. Taken the battery out and in to see if that helps but no it doesn't. The phone is 18 months old.
Any help will be gratefully received!
