I made a clean install of Windows 7 for comparison with Windows 8. I selected "on" in "Allow hybrid sleep". I checked from Windows 7 the sequence described in the preview comment #16 :
1) after using Win7 "Sleep", out of sleep mode and "Restart" : Win7 NOT Hibernated
2) after using Win7 "Restart" : Win7 NOT Hibernated
3) after using Win7 "Restart" : Win7 NOT Hibernated
4) after using Win7 "ShutDown" : Win7 NOT Hibernated
5) after using Win7 "Restart" : Win7 NOT Hibernated
6) after using Win7 "Restart" : Win7 NOT Hibernated
At each step, I found the same value for the header and md5sum :
head -c 8 /media/Win7_partition/hiberfil.sys | od -t x1
0000000 00 00 00 00 00 00 00 00
0000010
md5sum /media/Win7_partition/hiberfil.sys
cb2814bde2ff2d8602919a34120be7ac /media/Win7_partition/hiberfil.sys
Under the same conditions and in the same PC, there is no problem with Windows 7. Whereas for Windows 8, "hybrid sleep" is a disaster.
