It's not that the new drive doesn't show up. If a new drive is installed the Snap won't boot. It just goes into the power/disk blink mode.

If this helps, the drive that died was on the top. And the jumpers for both are set to Master.

The drive that is good is named "Mirror Drive Failsafe".

Do you think that I should move the good drive to the top and the new drive to the bottom? Does it matter for booting?

Thanks!
