Hello, this just means that the data read from the drive after flash is not exactly the same as the one in the image.
This can have 2 meanings:
- the flash drive has broken sectors that do not write what they are asked to;
- something writes data on the drive in the moment between Etcher finishes writing and the moment Etcher finishes verifying.
As this image contains a fat32 partition (the second one) and you’re using Windows, it may be Windows creating a System Volume Information folder on that partition.
If that’s the case, you can use the drive normally, it should boot fine.
