So i gather from everything i have read that there is no way i can add 2 new drives to the empty bays 3 and 4 in my 343 and not lose the data on drives 1 and 2. NO i not running any raid at all and no plugins or addons at all. I know i should have a backup, and I do it is on drive 1 and 2, some of the data is irreplaceable and some is not, the time it would take to go through and sort is just to great. I do not have the ability to copy it anywhere at the moment.
So if you tell me that there is no guarantee that my data is safe, I will have to wait till i have the money to buy a back up for my back up, or wait until i have saved enough money to buy a new NAS that actually works the way it should and also maybe one that uses the same drive structure as my system so that the drives are hot swappable.
