I recently got a RPI which came with an 8 gb micro sd and that was too much so I used a 2 gb. later when I try to access the 8 gb card it automatically formats it to 1 gb. IS THERE A FIX?
Sounds like a corrupt partition table on the card. Do you have a micro-SD adapter card so you can format it in a camera?
I recall that worked for me a few months ago when I had that same problem.
