mad G.I.
I bought this card, originally for my Galaxy Note II, with the intentions of using it as my primary downloader, but I could not get it to format correctly for the phone, even using third party format software.I then tried it in my Galaxy Tab2 7.0plus......same problems.I finally, and ridiculously, put the card in my Nikon D5100 camera. I could take a whopping 8k photos, on high/large settings (not that I would ever need to take that many photos in one session). This was the last option I had, to use the card.It worked well, taking photos of a holiday, and thankfully, it did not fail before I could get my photos onto a computer. Since then, I have inserted it back in the camera, and reformatted (like you always should), and bam, one photo is good, after that, failure, every single time. So now I have a 64GB card, that is capable of taking and storing ONE PHOTO at a time, before I must run a "fix file system" on my computer.Don't waste your money on this card, over priced, not really faster than the other cards I have, and zero longevity. This may be a one off, but I think it is a problem created by the proprietary format exFAT, that makes this card a loser, or more to the point, the poor customer who buys it.UPDATE JULY 2012After contacting sandisk, they have offered an RMA, but first they must verify that I have not tried to "recover" or "wipe" the data on the card, and I must ship it, at my expense, to Taiwan. I have since emailed them in reply to the requested information (date of purchase, photos of the card, packaging ect), and I told them that the data on their is my data, and if I could have accessed the card, I would have wiped it, why should I give them my information, stored on the card? That makes me less than happy, I am guessing that they want to discourage returns. Who would want to send data to a company, not knowing who will access it, and what they will do with the information contained? I would have wiped the card, but it was unreadable, unable to format, unable to do anything. I will send it to them, hoping that the information is destroyed, along with the bad card.Sandisk, you are asking a whole lot of your customers, and since this card has gone bad, I have had several other cards from them, go bad as well, seems to be a whole lot of cards being shipped that die in very short time periods. I used to love their products, and their older flash drives are great, still using a micro cruzer that is 6 years old, and going strong. I have not had one single microSD card, from this company, last more than three months, since I moved to the Philippines. Either they send their junk to the Philippines, or they have dropped QC from their business model, to create higher profit margins.**UPDATE 2**After emailing Sandisk, and expressing my displeasure with having to return the item, intact, so that they can "assess" the card, and look at/recover what ever personal information may have been stored on the card, they rescinded. I can only assume that they want to get the card back, to verify that it is bad, or make sure that you are not just trying to get a free card out of them, which I can understand. Instead of requiring me to send the card back to them, they asked that I cut the card, and send a photo of the "destroyed" card, so they could process a new card, to be sent to me, directly in the Philippines. I hammered them pretty hard in this review, and in the email I sent to them, regarding the bad card, and sometimes, you get results, in this case, I give them 5 stars for doing the right thing. I had no problem cutting the card, since it would not operate in any of my devices anyway, but I did have a problem returning the device, intact, with out knowing what information was stored on the card (banking, amazon account info, passwords, ect.) I would have just kept the card, destroyed it, and never bought another from sandisk. With their faith restoring gesture, I will not remove them from my list of companies to avoid. I just hope that they get better at QC. I returned another defective card to the retailer yesterday, only to find out that you MUST have the original packaging for a replacement. I was lucky to still have one of my packages, but since I bought several of the cards, I am not sure if I gave them the matching package for the card I returned.I would suggest that if you are like me, and have several devices (2 DSLR's, galaxy Tab2, galaxy Note 2, SII, LG-P920), that you find a way to mark each card/package, and keep the package, in the case that the card should go bad. I have had more than half of my sandisk 32gb cards, fail on me, in less than 6 months. I only buy them, because of the cards available in my area, these are the best, which is scary, with such a high failure rate.
