[SOLVED] hard drive partition

[NighthunterX]

I have 2 hard drives, one is WD Black 500GB(current windows drive) and other is 2TB WD Blue(data drive). Both drives has 2 partition each.
I wanted to change the 500gb to an Samsung 860 ssd and do a clean installation of windows 10 in the ssd.
I know I should remove other drives except the drive that is used to install the windows 10, but what happen if i detach my drives and attach it later? will it lose partition and data in it? Or the partition and data is still there when plugging it back?

Nothing is lost.
It may be necessary to assign drive letters to partitions on your old drives after reconnecting them.

• So does it mean that I don't need to format them to use it again normally?

Formatting means - you loose your data.
If you want to keep your old data, then do not format.
