Lost RAID1 on Gigabyte GA-Z170MX-Gaming 5

System build from August 2016:

Windows 7
Gigabyte GA-Z170MX-Gaming 5
Intel i7-6700K
BIOS RAID1 of (2) 500GB SSD (Samsung 850 EVO)

This system has been running fine until about two weeks ago, when it started intermittently freezing and rebooting several times in a day. It happened once during startup so I tried firmly pushing all components into their respective sockets and the problem went away.

Today it happened again, so I firmly pushed components, but this time Win7 doesn't complete startup. The bios setup under "Perhipherals : SATA Configuration" shows the drives as AHCI when it should be RAID. After setting it back and rebooting, the RAID manager (Intel Rapid Storage Technology) no longer recognizes it, showing both drives as "Non-RAID Disk".

Windows recovery suggests it is able to recover 2 of 4 partitions. Is it safe to proceed with this route, or is there something else I should try? I have a backup from a couple weeks ago, but I'd like to recover recent files if that's possible.

Any recommendations?

  1. I'm able to recover all the files, but I'd rather not have to reinstall the OS.

    Does anybody know how to restore the RAID?

    Problem solved. The other drive was fully bootable, so I was able to rebuild the RAID1 in Windows.
