I tried to format a USB Stick in ext4 with Gparted, Mintstick and the terminal, but nothing worked. If I copy files to the stick (in this case .mkv), they will be corrupted as soon as I insert the stick again.
This problem occurs on two different computers and with two different USB Sticks. I have already tried to change the kernel (4.14.141-1, 4.19.69-1, 5.2.11-1) without a positive result. The two USB Sticks work perfectly under Windows 7 with NTFS.
Is there a solution for this?
I use Manjaro 18.1.0 with KDE.
