@ PeRRo_Rojo:
Thanks for your intensive tests and your very interesting report, which verifies, that your shutdown issue obviously is caused by the following combination:
- OS: Windows 8.1
- Storage driver: any Intel RST(e) RAID driver v12.x.x.xxxx except the generic iaStorAV.sys (v12.0.1.1018)
- Drives connected to Intel SATA ports: 1 Intel RAID0 array + additional HDD or RAID0
Now it is Intel's business to find the reason for this shutdown bug and to solve it.
Good luck!
Fernando
