You convinced me. @Theodore Tso: Thank you for your detailed post.=20 As I wrote in the first post, i tried f2fs once and it also broke the data. This confirms your claims. I tried the =E2=80=9Ebasic-veryfy.fio=E2=80=9C. Unfortunately, this method = is not very practical, because in the case of my pendrive, the verification time is abo= ut 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, bec= ause you can operate on hardware that is not fully functional, not be fully awar= e 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 ca= n do is throw this equipment in the trash. Thank you again. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
