I am using 4 drives, RAID 10 on ASUS X99-E WS/USB 3.1, Windows 10. If I boot the PC, the raid is fine. Everytime I reboot the PC, I am missing 1,2 or 3 drives. This happens systematically.
When PC is off and I simply boot it, all drives are always present.
Any help or advise please?
You mean it happens systemically? 😜
Simplest thing to try first is disabling both BIOS and Windows Fast Startup and see if this helps. Second thing is to look into whether there are any BIOS updates available. Third thing is to ask Asus support whether there are any known issues with this motherboard.
I will try the first thing. This started after upgrading BIOS to latest version so second option is out.
Thanks for correcting, I never used that big word before in English :)
Thanks for your help
No problem. I hope you can resolve this - without having to delve into RST release issues (but remember that RST runs from firmware and the firmware comes as part of the BIOS, so you're back to looking for BIOS updates from Asus then).
Based on the description of the issue, and the fact that it only happens when you reboot the computer, this seems to be related to a hardware/BIOS issue.
As recommended by n.scott.pearson, we suggest that you contact your Original Equipment Manufacturer (OEM) and make sure your system is up to date (e.g. BIOS).
