DevaVictrix: Thank you very much for joining the Intel® Rapid Storage Technology communities.
In order to better assist you, could you please provide the system report from Intel® RST?
Please, do not try to create the RAID 1 from the control “i” menu because by doing that the information on the hard drive will be lost.
Any further questions, please let me know.
In the end I had to transfer my files to a couple of external drives, rebuild the array and transfer everything back. The really annoying thing is that the new BIOS sometimes crashes on bootup so I could do with rolling back!
Thank you for your response.
Hi DevaVictrix: You are welcome. It is great to hear that you were able to transfer the information. In regard to the BIOS, yes, you can always try a roll back to an older version. If you do that, please disconnect the hard drivers, then once the downgrade is completed, get in the BIOS set the SATA mode to RAID and then connect the hard drives again. To have a back up of the data it is always recommended.
Any questions, please let me know.
