HDD starts being used by windows instead of my SSD after hibernation

My thoughts.

Because you have pagefile on 'D' when coming out of hibernation it's using pagefile to go back to the same place it was (D-page file).

I believe if you put pagefile back on 'C' things would be normal.

I haven't tested this method because I have always left pagefile on the Windows 'C' partition.

Having only 9% free space on your 'C' partition could also cause problems.
Windows 10 needs 10% or even 15% elbow room to work properly.

Using Sleep rather than Hibernation is a much quicker solution and Hibernation requires loading data back in memory. If the pagefile is on the HD it will also slow the process down.

But why did Windows put the pagefile in D, because i have low disk space in C?

Could well be since you say you let Windows manage it entirely.

Is the large amount of space occupied on C due mainly to a lot of or some particularly large programs (thus not seeming moveable to D: ) or is a large bit of it data?

You really should consider relieving that congestion on C: drive (per my prior and Layback Bear's suggestion) even if your weren't having the D: drive activity problem, it's really rather tight at 91% full.

If you aren't able to conveniently breakdown what's occupying the most space on C: drive, here's a link to a freeware utility called Wiztree that many here use and can make tracking down that usage by folder and sub-folder very easy: http://antibody-software.com/web/sof...ur-hard-drive/

It's hard to release any more space, i have unreal engine 4 installation and my project there (and i need them to be in the SSD to really benefit from the speed so it doesn't compromise my workflow). I'll try to use windirstat to see if i can release some space.

Might want to check your system restore allocation/usage if you haven't already done so. Of course, this is all further down the path of being able to have page file on C: drive and presumes that is the root of your problem - not sure we have that 100% at this point.

BTW - @xlar8or , since you took the Fall Creator's Update over the last month or so, have you done a Disk Cleanup (system files option) to clean out Windows.old (assuming you don't need to roll back) and tidy up any other unneeded files from C: drive? Windows.old could be taking up a goodly chunk of space if it's still there.

If you need more space on your ssd you have a few choices.

1. Remove data you don't use often to another drive.
2. Turn off hibernation.
3. Get a bigger ssd
4. Less space used for Restore points.

After you have done Clean Disk you should reboot, sometime two times.
