4. Select a disk, an SD card, a flash-drive:

“Writing” and “Verifying” columns must contain the same number of megabytes (the whole SD card or flash-drive size, if it was empty).
It’s recommended to use this program for verifying all the flash-drives, SD cards and disks after buying, especially if you buy them in China. Unfortunately, a level of fraudulence remains high among Chinese sellers. Far too often, they sell allegedly 128 gigabyte flash-drives, which prove to be 4 or 8 gigabyte ones.
