I am "trained" to properly disconnect any external harddrive (USB) before unplugging it. I am using the normal "safely remove hardware and eject media" function in Win10 for that. I am not even sure if this policy is still necessary or is a remnant from the old days. I recently connected a WD drive with external enclosure and an on/off button. Do I still need to do the above procedure in this case or can I just turn the device off on the enclosure in such a case. I find that the device often appears to be inactive (only used for backups) and going through the above procedure seems to awake the device first which seems redunant.
