Towit solemnly promises: All the memory cards we sell are of genuine, full capacity, and there are no fake capacity cards!! It is recommended to use the disk software H2testw for testing, so that the expansion card and upgrade card return to their original state Method to test whether the memory card has false capacity Method 1: Use H2testw for testing. Method 2: A simpler method, for example, testing 8GB, can involve storing more than 7GB of music or videos. If all of them can be read normally, it means the card has sufficient capacity. If it is an expansion card, only the files stored at the beginning can be read, and the extent of the expansion will determine whether the files at the end are damaged and unreadable. The test data in the image below is the result of testing with the H2testw software using a USB3.0 card reader.Test data is provided by the internal laboratory and is for reference only. The test data in the image below is the result of testing with the ATTO software and a USB3.0 card reader.Test data is provided by the internal laboratory and is for reference only. The images below are all actual photos of our previous factory shipments, including shots of the inspection and copying process. They have not been photoshopped, so please do not use our images without permission. The actual usable capacity of a 2GB memory card is about 1.85GB, because computers use binary and manufacturers use decimal when producing them For computers, 1MB = 1024KB, but for manufacturers, 1MB = 1000KB. Calculating this, 2GB is approximately 1.83GB, 4GB is approximately 3.7GB, 8GB is approximately 7.3GB, 16GB is approximately 14.6GB, and so on. How to identify genuine and fake cards? Currently, many expansion cards on the market are upgraded by using 1GB or 2GB or 128MB, 256MB capacity and falsely labeled as 4GB, 8GB, 16GB, 32GB, etc.In reality, the capacity is still 1G or 2G, and buyers cannot visually tell whether they are getting an upgraded product. A simple way to check if a card has sufficient capacity is: if a 14.9GB card copies approximately 14GB of data Upload the files, songs, and movies, then delete them and remove the card reader from the bottom right corner of the computer If all files can be read normally, it indicates that the actual capacity has been reached If it is an upgrade or expansion of the memory card, the actual capacity is only 128M/256M/512M/1G/2G The upgraded capacity is usable, but the data copied into it afterwards is virtual Unable to extract, or damaged!!!
