I'd like to know how that MTBF was calculated. I bet with the card mostly sitting in your backpack :)
I had a card go bad, once - IIRC it was a Transcend. The camera (an *istD) was "writing" the images just "fine", but the file wasn't (like it had a "bad sector" it couldn't write on). Since then, all my cards are Sandisk; and I had a Sandisk going bad, too, completely fried - but that was because of some lousy reader. Since then, all my readers are Sandisk&Lexars :) The camera behaviour seems indeed reasonable. -- Best regards, Alex Sarbu -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
