Hi! I have the same issue, but worse. After this error code I rebooted my PC, and it took about 5 minutes to boot up again, and when it booted I noticed that the drive - that produced the error code when I tried to make new folder - was missing. It isn't shown in file manager and in the disk manager neither. Now I don't know what to do...
