I bought a new Extreme Sandisk SD card for a European trip in early May. It worked well for 1200 photos and then suddenly I received an error message saying the card was faulty. What was different was that after that message the card would not register on any computer or the camera–it simply wasn’t there. SanDisk Canada has indicated that this may be a manufacturing fault and their proposed solution was to send it to a US data recovery firm. The charge for a 16GB card is $225US plus the cost of registered postage. SanDisk’s only offer to me was to replace the card-they wouldn’t even cover my postage costs let alone any recovery costs. A local data recovery expert has advised that this was probably an electrical issuer as the card doesn’t register and recovery may well not be possible.
So two lessons–beware of the Sandisk Extreme 16GB card as there may well be others with manufacturing faults and second, do not expect anything in the way of assistance from SanDisk. They seem to care little for either their customers or their reputation.
As a footnote, before sending the card to their suggested US data firm (presumably a lucrative business) they require two calender days to send me a simple authorization so that they then get the card back at the end of the process. .
