Hibernation on Windows 10

I understand that we should not use Windows 10 Fast Startup with BIBM, and I have disabled it both in BIBM and in Windows 10.

But what about ordinary hibernation? Is that dangerous also?

I don't know the answer to your question but want to point out one thing
about Fast Start so every one else knows in case they haven't noticed.

I had it turned off but this evening after the Creations Update now making
it Windows Version 1703 and OS Build 15063.138 it was turned back on so had
to turn it off again.

Isn't it pretty obvious when it gets reactivated?
The bootup would be SO fast as I recall.

Yes and no. Problems can arise when you access the same data partition from two different operating systems.

Example: I have Windows 7 and Windows 10 in separate partitions on my laptop. Both are booted as the "C:" drive, but both share my "D:" and "E:" data partitions. If I make changes to my data files using (say) Windows 7, then hibernate Windows 7 and boot Windows 10, Windows 10 may not be able to see the changes made using Windows 7 (because those changes were still in the disk cache in RAM when the system was hibernated). Worse, if I now make changes using Windows 10, the effect may be to corrupt the file system, either when I use Windows 10, or later when I reboot Windows 7.

Provided that you understand this, hibernation is safe. I routinely use hibernation on my laptop. This allows me to keep files open that I am working on, and the next power-on is much quicker, because I am waking from hibernation and not rebooting. However, if I want to boot operating system "B", and I had previously powered off by hibernating operating system "A", I first start OS "A", perform a full shutdown, and then boot OS "B".

That is true if you are booting an HDD (mechanical hard disk). But if you are booting an SSD, the boot process is so fast that you may not notice the difference between a full boot, and a wake from hibernation (which is what "fast start" is).

OK, so I think everyone is saying that straight hibernation has the same danger level as Fast Startup.

I had thought though that Fast Startup only hibernated the OS files, in which case shared data partitions would not be a problem. Is this not correct? But messing with the partitions in any way would still be risky.

I thought Fast Start just delayed loading certain drivers until turned over to the OS to make booting faster. Am I confusing two different things? Has something changed that I missed?

Thanks Brian, I've been avoiding 8 and 10 like the plague.

Now that the Creators Edition is out, I'm going to give W10 a shot and see what the new sound scheme does, if anything, as applied to digital audio workstations.

I love both. Especially Win10.
