March 15, 201610 yr Can i ask for a bit of assistance please? I have successfully replaced a 6TB parity drive with an 8TB and parity is again valid. I now want to use the old parity drive to replace one of the existing 4TB data drives to give me an extra 2TB of space. What steps do i need to take to achieve this? Is it as simple as removing the 4TB and inserting the old parity disc in its place? Will the system recognise the missing disc and rebuild or not? And .. do i need to preclear the old parity drive before i reassign it as a data drive?

And .. do i need to preclear the old parity drive before i reassign it as a data drive? Assuming the disk was working OK for a while and there are no pending sectors there's no need to preclear.
