OK...here's where I am now.
I disconnected the defective drive (actually, Seatools has repaired it, and now states it is good), and attempted to reboot from the second drive. Well, to my surprise, it booted into Safe Mode without my having to delete the RAID or adjust any settings. So, I took the opportunity to finish the steps as described in the Microsoft support web page (http://support.microsoft.com/kb/307545
). I had done Step 1, but needed Safe mode to complete Step 2 - which I did. I then got into the Recovery Console to complete Step 3...then attempted a normal boot to complete step 4.
Well again, I was shocked that it started to boot. After the XP screen, it started a chkdsk. Well for 20 minutes, it was "recovering orphaned files." When finished, the screen went black - no boot.
So, I began to think I missed an opportunity while in Safe Mode to take a different path (not that I know what it is). So, being that the supposedly defective drive is an exact mirror of the other drive, I then disconnected the drive I had been working with, and reconnected the defective drive. Well, like the first drive, I am now in safe mode. I am taking the opportunity to save some files to an external drive (even though I have most important files already backed-up), but I don't know where to go from here. I figure the other drive is now corrupted, and we have one final chance to succeed with this drive.
There is no System Restore available - probably because I completed Step 1.
Any ideas of where to go from here? I now have 2 boot drives in different states.
