Believe it or not , its in the FAQ.
Just did it for slot3 (counting top down) now it says sync for 31hrs!
1) turn off 2) swap drives 3) turn on 4) say yes to format and auto sync... wait long time

formatted new HDD outside of toaster, shut down unit, inserted new hdd, powered on 343, formatted HDD again, rebooted, checked status, then initiated manual rebuild.
HARD DRIVE INFO :

keeping fingers crossed, but it appears all data is still there & accessible
