Hello i just bought a WDRED 4TB and pre cleared it and now i want to replace it with my old parity drive which is a wdgreen 2tb. I haven't done this before so how would i go about doing this? Do i need to physically remove the old parity drive and plug it in to another slot and put the new 4tb into the old parity drive? And will i need to preclear the old parity drive again to use it as a data drive? I would really appreciate some help thank you. Or if there is a guide or tutorial about this that you can link me to i would appreciate it thank you.

See the "how to" link in my sig.
