RAID 1 noob question (alien.top)

Excuse me for this stupid question.

I am using a 2-drive case with RAID-1. I did some simple testing by writing to the drive, and took out both drives for inspection: files are there in intact. Great.

Now if one drive dies I still have the other one. Great.

My question is, how do I use a 3rd drive and rebuild this RAID-1? Keep the good drive in the case and just insert the 3rd drive, and the case SHOULD get the data across?

According to the case manual, I need to press the reset button to get things going…. I’m afraid this will also erase the good drive!

As mentioned, if a drive dies, you just need to take it out and replace with a new one and start RAID rebuild. The vendor should have a guide on this with detailed steps.
