Nice you were able to get some of your stuff back.
When mine went down the last time and I didn't know what was going on it started a checkdisk that was like you said, reading files like it was christmas, it went on for a very long time and in the end the Raid was dead.
The files that were saved on another disk were mostly there in the recovered super invisable file loctaion that only MS knows now to get there. I can't remember what it was called but I can find it of anyone needs.
I was able to copy the MyDocuments folder like you said and get that stuff back, most of it came back fine but I did lose some things.
I tried in vain to find a recovery boot DVD that I could boot and then be able to see this super invisable file loaction and get the rest of the junk off but after awhile I gave up.
As far as I know when Raid 0 setup go down you lose everything, period, you were lucky to be able to get stuff off. Raid 5 is def the way to go and run Accronis and remember to keep a Accross recovery disk up to date
