Many thanks for your help.
I did go to Disk Management and after a few clicks found "RAID 1 Properties" with the notice "The device is working properly" which is great news. However, without Intel Matrix Console installed, I am not sure how I will learn if one of my hard drives has failed. A few years ago, one of the original drives failed. I bought a replacement and with the aid of the Intel Matrix Console it was installed rather quickly and the RAID 1 configuration was back with two working drives. Then, about two months later the other original drive failed so I repeated the process.
I got into my current situation when my computer had some corrupted files. I spent much time and effort trying to fix it without success. So I backed up my files and did a factory restore from disks that I had made when I first purchased the computer. That went OK but it took about a day or so for all of the Vista Home Premium updates to download and install. Then I used my Windows 7 Home Premium DVD to try to update the operating system. The update did not work since Vista SP1 did not install despite the Windows Vista update list showed several times that SP1 was successfully installed. After trying to get SP1 actually installed, I gave up and did a clean install of Windows 7 Home Premium which included SP1. That step, of course, wiped out Intel Matrix Storage Console.
