Hi,
Great news and you're welcome,
Yes fast start inside win-10 is really a hibernation state so 10 is not really shut down completely
And yes it is very annoying and multiple hdd harming if dual booting with another os because it trigger check disk for errors so there is a real chance of corruption happening,
Merry Christmas and Happy New Year with another win-7 install :)
Win-7 is on the M$ hit list
Keep the watch out
Cheers.
