Hi M17,
Have you tried connecting only one of the Seagate drives and use out of the RAID? I would try connecting one of those drives in another PC, as secondary storage drive. Check if the drive will be accessible. Search for it in Disk Management. Does it have a proper file format? It would be really strange if both drives have failed simultaneously. You may need to use a data recovery tool in order to save your data. Once you have it backed up, format the drives and check their condition with the drive manufacturer’s diagnostic tool. If all seems fine, form the mirror again. Check the link below for some data recovery software suggestions:

It may be helpful connecting one of those drives in a Linux PC. Unix based systems show pretty good success rate when it comes to drives with problems in performance and connectivity. If you do not have access to a Linux PC, use a Linux Live version and boot it from a flash drive.
I would also check for some BIOS and motherboard SATA drivers updates because when having RAIDs, stability is a must. If all goes well and you manage to restore the data and the RAID, I would advise you to keep a backup of all important data on an external device.
Hope this helps

Solved!
Thanks R2D2_WD for your suggestions. They helped put me on the right track.
I tried a several file recovery and other hard drive utilities but nothing seemed to be able to do much. I then found a recommendation somewhere to try Paragon and it was perfect! I used the free "Paragon Rescue Kit 14 Free" to create a Win PE x64 rescue disc and then booted from that. From there, it was easy to repair the drive information and all of the data and the drive became accessible again. I copied everything over to an external HDD (except for two unimportant corrupted files that were probably corrupted at some much earlier date but not noticed). All of the copied files are perfect and match what's on the revived internal drive that had failed but is now working as it was prior to the problem.
I did this to only only of the paired drives so far but I plan to reformat the other one and then mirroring them again with RAID 1.
I still don't know what corrupted the drive information initially but I suspect that it might have been some malware. I will do some full, deep virus scans to make sure that the culprit isn't still somewhere in my system.
I'm very impressed with the Paragon software. It was very easy and effective and was able to do what other paid and free applications were not able to do. It's great that it is free of charge -- especially for a fully functional version. I am now going to buy the commercial version mainly just to support their great work.
Many thanks to R2D2_WD and Paragon!
