KB4093112 installs, reboot, few seconds to load, notice hard drives are missing from explorer, check disk management, minus 1 drive of the 6 in the system, reboot again takes like 5 min to load to the login screen
3 are internel, 3 are external and all show up in the bios but not in windows, they all worked before this update.
3 are amd sata, 3 are on marvel gsata controler, some drives are totaly missing where others were somehow reassinged to a "difrent connection" when none have been physicaly moved.
Gpt partition sceam on every drive, formated to ntfs 4k clusters in win10 pro 64x.
Power settings are unchanged as well as other power settings.
Another fine mess MS.
