game sir sata adaptor for ps2 troubleshooting

I recently bought a game sir sata adapter on aliexpress. it seems to work and i formatted the 500gb hdd I put in it no problem but since it has no network port I guess i have to actually load the hdd into my pc to move games. my problem is it's not showing up except in crystal disk so do I need to use a specific program to move the games or what?

also does anyone have an elf for HD loader (not opl) so i can backup my disks to this hard drive?
