Not sure if this is the right section.

My W910i recently started to corrupt files on the memory card, and since yesterday, the whole card gets corrupted. The card worked fine for 4 months. Now the whole thing goes corrupt for no apparent reason.

I re-installed the software via SEUS, but no luck.

Currently have a 1GB Sony M2 card.

Is this a known issue? Or is it a possible memory card fault? What is the best way to resolve this? Any advice?
