OK, I finally got mine to work and there are a few steps more involved than above.

First of all, my problem was that the BOOT drive had failed (the top drive). It will boot off the mirrored drive (bottom drive) but it won't rebuild a new drive from there!

So, I bought an exact replica drive (Maxtor 250GB IDE) and put it in the bottom slot. I moved the bottom drive to the top slot. Only then did I eliminate the blinking light, reset mode.

Once I had the backup mirror drive on top (it was now drive 10000), the Snap booted up. However, disk status showed a cracked mirror. I could not rebuild the mirror because it saw the new drive as a separate drive but was still looking for the rest of the mirror. So I had to break the mirror by making both drives individual drives, then re-establish the mirror. This started the rebuild with no loadd of data! Yeah!

The exact steps are below.

1. Put good drive in top slot of SNAP.
2. Put new drive in bottom drive of SNAP. Turn on SNAP.
3. Reformat the new drive by executing the following command from the ipaddress/config/debug web page.
Note: DD is the number of the problem hard disk.
co de format 100DD /reinit
In my case it was
co de format 10010 /reinit
(After reboot, this configures 100DD as a SINGLE drive and FORMATS it.)
4. Reboot the Snap server.
5. Noww break the mirror with this command
co de config individual 10000 10010
6. Reboot.
7. After the ORPHANED disk is formatted and the drives are converted to individual drives, execute this command from the ipaddress/config/debug page.
co de config mirror 100SS 100DD
SS is the source disk, DD is the destination disk.
In my case the command was
co de config mirror 10000 10010
(This step mirrors the drive with data to the drive without data.)
5. Reboot the Snap. If everything works according to plan, the View Disk Status
page should report ?Rebuilding backup disk? when it comes back online.

Mine took about 4-5 hours to rebuild all 250GB!

Whew!

Hope this helps someone else!
