Sure, what followed: since the whole remains unnoticed at first, the system fails to boot, it hangs. If, in the UEFI BIOS back to RAID, the RAID BIOS then indicates that the boards would be reorganized. However, as is happening for hours unfortunately nothing and the RAID is 'shot to pieces'. Well thank you! As one may equal the Windows reinstall again after touches either the RAID function deactivated entirely or even new.
It should be a RAID-1, so ensure a reflection of the two plates, for greater data security. Wiedermal it is found that an additional RAID controllers for PCI or PCI-E is a better choice.
Yet what Doofes:
If you install from the CD Asrock via one-click all of the drivers, a lot of useless junk is placed on the plate. Annoying. Unfortunately, the other Mainbaordhersteller often make similar. Does not a man!
Conclusion: Actually a good and recommended motherboard with a few weaknesses in the area and RAID driver.
