[SOLVED] do modern mechanical HDD's require AHCI support

hello,

I am helping someone replace a failing hard drive in their old computer. the computer is a Q6600 build and has an asus P5n-w SLI motherbord with 4GB of DDR2 ram. at first they wanted to replace it with an SSD drive but the SSD never gets detected in the BIOS and after reasearching on the web it point to the problem being the asus P5n-E motherbord does not have support for AHCI.

so now they will be needing to replace it with another mechanical HDD.

so just to comfirm do modern hard drives need ACHI support like SSD drives?

Thanks
