Hi!
I encountered yesterday an odd problem after enabling Fast Boot and setting SATA Support to Boot SATA Drive only during POST. After I put my PC first to Hibernate/Sleep and then woke up PC, all RAID SATA Drives disappeared in Windows 8 x64 Pro AND in UEFI. I have installed Windows 8 in UEFI mode and boot drive is a single SSD drive. I have two RAID systems, one RAID0 with two SSDs and one RAID1 with two Samsung F3 HDDs (legacy from previous WIN7x64Pro system).
I restarted Windows OS and RAID0 SSDs were identified again in UEFI but not RAID1 HDDs. Only after Power Shut down and On cycle RAID1 HDDs were identified again.
I installed new Intel RST drivers v12.7 (from ASUS support) but this did not help. Then I used RST tool to verify RAID1 and this is running, 11h and counting, and over 10000 media block errors have been found.
I'm afraid now that this Fast Boot + hibernation combination has caused this. HDDs sounded very odd during boot up (crunch, crunch etc.) after waking up from hibernation/sleep.
Offtopic: I used hibernation because for some reason Shut down -button in my Windows 8 setup does not have Sleep-mode (Balanced Power Option in use) to be selected. Strange!
My rig is in sig.
