So far that's 2/4 of that particular model. The 1 Gb cards have never given me any trouble at all.
I'm sure my camera store will exchange this one for me, but...I think maybe Hoodman ran a batch with problems they didn't catch.
Until I started trying to use the 2 Gb cards, I was extremely pleased with the Hoodman SDs...fast, reliable, long-lasting.
Anyone else have a problem with these, or with any 2 Gb cards?
