here is the second time I buy this type of card: a brand Transcend CompactFlash and this time it's too I lost all my photos from a trip to India !!!! I had other different brand cards and they had nothing. The Transcend card once almost full, was buggy, I had to remove the charger then furnish .... until one stroke a message appears on the screen of the Canon device a SLR 350 OF unreadable card '. I handed another card and then everything works so well that not because of the photo equipment Then I did read the card on an external drive and there, no card detection ... Then I put my card to a professional photographer and computer scientist, no success either. The card was faulty from the start. So how is it that this is the second time and each time with a Transcend card I lose my data on the card ??????
