1. Hi there. Here there is a systematic error. I have lost files which I made changes. It happens after a reboot. And then, after a few reboots, I can find them on the Mac OS. In general, I have two OSs. In windows obviously, I can't find them too.
2. And the second problem is when I write files to a USB flash drive, afterward I can't read them on a win device.
Thanks
