Hard drives in array keep disappearing after reboot

[kalcol73]

So about a year ago, I upgraded all my drives plus had to add a sata card to accept all the drives all my parity drives on motherboard, but every time I reboot I drive mysteriously says it’s not found and not connected, but nothing is changed. What might be my problem. It does pick up the drive as an unassigned drive.
