The SATA controller on this old motherboard is still SATA1 (1.5 Gbps). SATA2 HDDs are usually backwards compatible. But on these old ASRock boards you might have to force the drive to run at 1.5 Gbps to get them recognized.
Some drives have a jumper for that, on some you can do it via a software tool, and on many new drives there is no way to force them to run at 1.5 Gbps anymore.
The drive you mentioned (ST500DM002) is a SATA3 (6Gbps) drive. I hope that I am wrong, but I think it is not going to work on this motherboard. Maybe contact Seagate and WD directly and ask them for recommendations for drives that can be forced to run at 1.5 Gbps. Then you also find out which manufacturer is the most responsive
