Have I lost data.

Recently, I have been backing up my DVD collection unto my server. Earlier today, I ran a parity check and during that particular process both the parity 2 drive and the disk 1 drive could not be read. I rebooted the server and when I logged onto Unraid I noticed that the disk 1 drive was unmountable and had to be reformatted. So I reformatted the drive thinking that I will not lose the data since I have had everything backed up in the parity 1 drive for months. I currently have the parity sync/ data rebuild process running as I am writing this. My question is this: Will I be able to get back all the memory that was on disk 1 back to said disk once the parity process is finished?
