Second HDD not recognized

An interesting question for y'all.
I have two GX620 Dells and I have just installed a second SATA HDD in each one.
The computers do NOT recognize either one of the added HDs. The original HDs are recognized.

Is this normal? Do I need to manually do something else?
I have NOT changed anything in the BIOS. Should I?
