Hey guys why crying for getting lower memory than its specified in cover. Its normal and no issues with your card. This is common in each and every memory storage Card,HDD,SSD etc out there in this world. The actual fact is memory devices run on MBR (master boot record) which take 2.5% to 4% of your actual available memory. Depending on the file system its use (FAT/FAT32/NTFS/NandFlash etc) the actual available memory will decreased. Just Imagine you take a blank paper and write something but if you need to write like a data sheet, you need to put margins depending on the data. Horizontally or vertically but you cant ask that why this margins eating up 3% of total paper size? Same thing happen with a storage device which 1st write a filesystem like margins. We called it "sectors" technically or MBR. Its also contains the firmware data which required the computer device recognize that memory card or HDD. These are the files/MBR/sectors consumed those space. So just chill and be happy. -Punyaslok Dash

I went ahead and purchased the Sandisk 64 GB SDXC card and while I was on Samsung ICS stock ROM it worked just fine. I am the tinkering type, so I flashed my SGS3 to CyanogenMod 9.1 (stable) and the card showed up as not recognized/damaged. Hunted around xda-forums I used the accompanying Sandisk SD Card reader, put it into an available laptop with SD Card slot, ran a "chkdsk /F /X" command and enabled the ability to copy files across to my laptop temporarily. Once files were backed up, I tried formatting as FAT32 but Windows 7 says its too large to be formatted with the FAT32 filesystem. I later learned that there are lots of problems with open source support for exFAT primarily due to Microsoft's patents on it; yeah go figure. The reason it works out of the box with SGS3, is Samsung built in proprietary exFAT filesystem support. The bottom line is, either go back to Samsung Stock ROM with all its bloat, to make use of the 64 GB SD Card, or stick with CyanogenMod and give up on being able to use exFAT-formatted cards. No complaints against Flipkart. Delivery was on time and as expected.

I was searching for 64GB memory card all over bangalore and i could not get it. Then i saw the add in TV and searched Flipkart. There was this memory card but in the web there was some comments that Class 10 cards may not work in Galaxy Note 2. But there was a user comment and he had purchased and it worked like a jiffy. I closed by eyes and placed the order. The order was fantastic. Delivered in 2 days. I like FLIPKART

So i bought the best 64 gig microsd card available in the market, it worked flawlessly for months but now the card is corrupt, luckily (sorta) the files are there but they can only be read, the card has become write proof and any data or file i put there is lost and restored to some time when it happened. Unlike most corrupt sd cards i didn't lose the data, but still this is unexpected from top class microsd card. I have no bill no nothing, i mean who'd expect this to happen on the first place. So i don't know about any replacements or warranty.

I was uncertain what to expect since online reviews suggest most devices don't support more than 32GB SDHC and I wanted to use it on an oldish Nokia (E63). Turned out it's fine. It is pre-formatted in exfat, which Nokia doesn't recognise, so I reformatted it (on the phone directly). It shows 59GB capacity (which is correct -- storage device makers use 1K = 1000, while computers use 1K = 1024). It also works with my USB cardreader. I have filled it up to about 2/3 (ie, well over 32GB), no issues so far. It costs a bit more than two 32GB cards, but if you have a large collection of music, the convenience is worth it. [UPDATE] I have now moved it to an Android phone, and it works fine there too.
