"Both Canon and Lexar have issued media alerts which describe issues discovered between several Canon digital SLRs and Lexar Pro 80x CompactFlash cards. Lexar is describing the problem as 'a lost image condition', which they say occurs only in extreme circumstances and can occur with other brands' cards too. As well as highlighting the Lexar problem, the Canon alert describes a problem with the EOS-1D(s) Mark II, which can lead to the loss of images still buffered. Firmware updates to fix these issues should be available by the end of this month. Full details enclosed." Yikes, though I doubt too many people will be affected by this, its still disconcerting to those who rely on flash media. Kind of makes you want to carry a backup device with you at all times. :?
