The RAID BIOS determines that there is a conflict on any of those hard drives, I recommend since you have RAID 1, resetting to Non RAID and check hard drive integrity for hardware errors.
Are you saying set to non-RAID and do chkdsk /F on both of the drives then turn RAID1 back on? I have the same problem after the machine wakes form sleep. The Intel RST goes into Verifying and Repairing for about 8 hours.

Volume1, RAID 1:

It is correct. By setting the Volume to Non-RAID, it will let you check and test the Hard Disk Drive without loosing information.
I have not tried the resetting to non-raid yet. I turned off sleep mode and the problem has not occurred since through several power down and restart cycles.
I think the issue is with entering or exiting sleep mode. Any ideas?
The Intel® Rapid Storage Technology or the RAID function should not be related to the Sleep mode or S3 State; however, I will forward the feedback to the corresponding department for future considerations.
I would recommend you updating the drivers in your system including the BIOS chipset and also, as mentioned before, setting the Disks to non-RAID and testing the system.
