Interestingly enough I'm getting ready to post a RAID recovery and migration guide.
Chances are your RAID and all its data is toast, I assume since you used a RAID 0 array vs a RAID 5 none if it was important and what was is backed-up?! Right?!
Quite often if the drives are 'missing' it's one of three things if the MOBO is good: 1. the drive is bad, 2. the power and or SATA cables are loose (check all connections), 3. the drives are 'Off-Line' which you'll see in the Intel RST/RSTE ROM post screen or in Computer Management / Disk Management.

The following is a work in progress (DRAFT):
Guide How To Repair or Migrate RAID on Intel RST/RSTE
This Guide will illustrate how to both Repair and Migrate your data and drives using Intel RST/RSTE RAID in Windows, specifically Windows 7. I recommend both a redundant RAID array and frequent backups of all your important data. Backups are great but that data quite often is not fully up to date so you can easily lose data and or hours of work between backup points.
Further, folks may want to take their data on a single drive and create or 'Migrate' their drive to a redundant array. Supported Intel chipsets offer redundant arrays which includes RAID 1, 5 and 10; RAID 0 is not a redundant RAID array.
Supported Intel Chipsets with RAID Migration:
Older Intel Chipsets -
http://www.intel.com/support/chipsets/imsm/sb/cs-020674.htm
LGA 2011 X79 and C600 series ** -
http://www.intel.com/support/chipsets/rste/sb/CS-033345.htm
LGA 1155 - (all Chipsets are supported
except H61)
** the iaStorA.inf driver must be installed at time of OS installation; i.e. (F6) or driver added.
Prerequisites:
* Intel RST/RSTE control panel and drivers must be installed properly per the supported OS (32-bit/64-bit)
* Intel SATA Ports only
* BIOS (UEFI) Intel SATA -> RAID
(AHCI or IDE are not supported)
* (2) or more drives HDD, HHD or SSD with preferably same or similarly spec drives ; lowest/slowest sized is maximum per RAID
* RAID drives may span both the Intel SATA2 and SATA3 ports or up to 6 drives in RAID 5 & 10
*
Recommended - drives that support error recovery control; TLER is not supported on consumer Western Digital drives
*
Recommended - BIOS (UEFI) Enable S.M.A.R.T.
Part 1 - Failure:
After the RAID array is configured in the Intel RST/RSTE ROM I recommend that you do not use (Ctrl + I) to modify the array. Doing so will erase all of the data across all of the drives modified. If the data is fully backed-up you can choose to fully reset the RAID array in the Intel ROM (Ctrl + I) then copy the data to the newly formed array. Alias's may be lost.
A.
Degraded or Single drive failure - the simplest fix if possible is to Reset the drive and allow Intel RST/RSTE to Rebuild the array. If a single drive fails and is replaced the Intel RST/RSTE should automatically detect the replaced drive and Rebuild the array, open the Intel RST/RSTE control panel to verify. On average it takes about an hour or so to repair a 1TB array.
Click 'Reset Disk to normal':
B.
MOBO Failure and Replacement - if the array was good and Intel RST/RSTE is properly installed including its drivers then by simply changing the MOBO the array will automatically work and in many cases not even require the array to be rebuilt. The Intel RST/RSTE ROM will recognize the array and no user intervention will be required i.e. don't (Ctrl + I).
Important - boot in to the BIOS (UEFI) Intel SATA -> RAID and Enable S.M.A.R.T. before booting into the OS.
C.
Unrepairable or Multiple drive failures - this can be a very disturbing form of failure when more than one drive fails the solutions vary with the different forms of RAID arrays. Often if the drives are recoverable it's either a sign of corruption or power including that of the MOBO and or PSU. In RAID 1 often one drive actually fails and can be recovered with some luck and efforts. For this Guide's purpose in RAID 1 if one drive can be salvaged then that data can be Migrated on to a second drive. Typically if a drive shows-up in the Intel RST/RSTE control panel it is recoverable, but if no drives show-up there are third-party recovery tools; Use at your own risk, examples: Runtime Data Recovery Software - http://www.runtime.org/ or R-Tools Hard Drive Recovery- http://www.r-studio.com/
Intel chipsets listed do not offer 'any 2' multiple drive failure protection as in RAID 6 where up to 'any 2' drives can fail. In RAID 10 (RAID 1 of (RAID 0) + (RAID 0)) you can 2 drives if only 1 of each (RAID 0) fails, but if both drives fail of one nested (RAID 0) then you have total loss.
In my instance the RAID became Degraded, Reset failed, and the reset in Intel RSTE caused both drives to fail and go in an 'Offline' state, and one drive has been problematic. However, the drive was seen and recoverable. Luck and RMA in progress through OEM warranty.
Part 2 - Migration:
Non-primary drives only. Migration allows you to take a single drive and transform a single drive into a supported RAID volume. Using the Intel RST/RSTE control panel this process is made easy if a drive and it's data is (recoverable) good. Click on big button 'Create volume...'
Warning - permanent data loss, other drives will be erased and lose all of their data except for the drive selected.
Configure - Name the volume, Select the drives, and most important choose the drive with the data to be migrated across the array.
Optional - Enable Write-back cache, use this option only if the system is stable and your PC in on an UPS (Uninterrupted Power Supply ; battery backup). This does increase performance especially with mechanical drives.
Check [x] Proceed with deleting data and click Create Volume.
Migrating will start.
Rebuilding an Migration.
Migration & Rebuilding completion.
If your drives are offline then you'll need to open Computer Management by clicking Start, right-click Computer and select Manage, and click Disk Management. Next right-click on the RAID array listed and select online.
Often if a RAID is recovered or create you may have some unallocated space. Right click on the array or drive and select Extend Volume and move and (add) the lost drive space and Next button.
Recovered space.
