I currently have a F2-221 with a single 2 Tb disk. I am planning to purchase a second disk of the same capacity (or maybe larger) and would like to install it without losing the data I have on the first disk in order to increase the capacity. My question is if it is possible to move from a single disk system to a JBOD system without losing data. Thanks a million

No, you can't.
You need to back up the data on the hard disk to another place and reinstall the system using two disks together.
Import the backed up data after reinstalling the system.

Ok, thanks for the quick response
