I checked the advice given to Ade and did the same on my D750i but the phone still doesn't recognise the card I got the 2gb card last week and I still have to make do with the 64mb card that came with the phone as formatting the 2gb card in the D750i didn't help. I also noticed that even the phone camera doesn't recognise the card as it says 'Memory stick not available' o.s.l.t. when the cover is opened. Please help!!
