Question Why does my older PC's bios detect my harddrive but my newer one doesnt?

[Notatallsvelte]

The new one is using a mobo, GA-Z68P-DS3 (rev. 1.0); the older one is using a ms7906 board; the hard drive is a HGST He10 10TB. Bios has latest update. Have tried known working ports and cables, SATA IDE and ACHI modes.

Thanks, Im going crazy, and not that savvy technically.

GA-Z68P-DS3 (rev. 1.0)
What BIOS version are you currently on for your motherboard?

Is updated, nvm its something to do with new sata standards, a stupid design decision and old PSU's.. possibly.
Wasted my entire day on this BS have now ordered a molex to sata adaptor and praying I get one that doesnt set my PC on fire.
