OK, thanks. You convinced me.

@Theodore Tso: Thank you for your detailed post. 

As I wrote in the first post, i tried f2fs once and it also broke the data.
This confirms your claims.

I tried the „basic-veryfy.fio“. Unfortunately, this method is not very
practical, because in the case of my pendrive, the verification time is about
60 days. After 10 hours I stopped. The progress was less than one percent.
Another properly functioning pendrive would also require many days. Perhaps
this method would generate an error, but it is very cumbersome.

From the perspective of the average user, this is not a good situation, because
you can operate on hardware that is not fully functional, not be fully aware of
it and not have an easy and effective method to verify the status of your
device. True, you can also buy hardware from a more reputable manufacturer.

Unfortunately, there's nothing I can do about it. Well, the only thing I can do
is throw this equipment in the trash. Thank you again.
