These devices usually work for any reads or writes of the first 8GB to the memory chip inside it, but any writes made to locations past 8GB, will either overwrite the data already in the 8GB chip(s), or the controller inside the device will simply not write the data at all, but signal back to your computer/camera/smartphone that the write worked fine! As the directory and cluster map of a FAT32 file system is stored within the first few 100MBs, the filenames will be listed by Windows Explorer or your camera just fine (until you try to look at that data that is stored past 8GB).įake 2TB devices are very common at the moment - you only have to look at the price to know they are fake! It's like sticking a Ferrari badge on a VW Beatle and selling it for 1/3 of the price of a real Ferrari and then saying everyone does it so it's OK! For instance a 64GB SD card may actually contain an 8GB Flash memory chip but Windows or your camera or smartphone will detect it as a 64GB device and even successfully format it as a 64GB device (though often, if you format it as NTFS, it may fail to format!). These devices are not 'faulty' per se, they have been deliberately re-programmed to lie about their size. This seller seems to think that it is normal for all cheap SD cards to be fake! It shows just how widespread the problem is. They have been deliberately re-programmed to lie to you!
