Look over this thread. Diskinternals has software that will reconstruct the raid on another box using usb connections. You could get the array mounted and copy your data
Sounds like the OS is corupt in your old array so it will not boot. Since you have the box working I suppose you could add some data to the shared folders on d: and try the recovery “keeping my data” to see if it actualy just reloads the OS and does indeed keep your data.
But with no backup, I think I would try the sysinternals. Free to try and see if it sees your data, you have to pay to actually recover the data
