Adding old unraid drive back to current unraid system

[Masalajam]

I replaced a 1 TB (Drive A) drive with a 2 TB drive in my 3 drive unRaid Basic setup about 2 months ago. There is now a 2TB Parity, a 1 TB data, and a 2 TB data drive in my setup which is working perfectly.

 

Since I was using the basic version, I was limited to 3 drives and took the old 1TB Drive A out of my array as per the instruction for replacing a drive. That process went smoothly, and the data was rebuilt on the new 2TB drive. I disconnected the SATA cable on the old 1 TB (Drive A) with the intention of putting the drive back into the array when I bought a Plus license.

 

I just bought the unRaid Plus license, and would like to add back the old 1TB (Drive A) back to the array. Before I do this however, I was wondering if switching a drive that used to be part of the array back into the system will screw anything up. Will unRaid see the old Drive A as a completely new disk and just format it for use in the array, the hoped for result;  or will it see the old Drive A, and become confused as to the presence of this old drive A which has not been part of the Array for months?

 

I'm using unRaid 4.7 (Plus version)

Any advice appreciated.

It will not remember it.

 

It will clear the drive (with the array offline for a number of hours) unless you preclear it.
