Know full well the problem lies with Windows 10. However, as explained in the Compilation of Windows 10 Methods, Steps and Solutions thread, Windows 10 Specific Method 6, Third option, it is possible to make a setting change in the “smb-global.conf” file that can potentially solve what is a Windows 10 OS problem.
Further, while I don’t think anyone has reported on it (or tried it and reported back), the v2.xx.xx firmware for the My Cloud appears (according to the User Manual for that model) to have an SMB setting within the Dashboard that may also potentially fix what is a Windows 10 OS problem by changing the setting from SMB 2 to SMB1 or SMB3 (if possible). See page 62 in the English User Manual.
