Only a few SATA ports work on Motherboard.

[terse plinth]

For work purposes, I have a few hdd's installed in my pc for redundancy. But for some reasons, my motherboard can only detect the SATA hdds only via some SATA ports. Is there a possibility that the motherboard itself has disabled some of the SATA ports for whatever reason? Your help is highly appreciated.

Page 8 of your motherboard user manual explains how the SATA ports work when an M.2 SATA drive is installed in the M.2_1 socket.

yeah, im using a sata m.2 as my boot drive. So my best solution to use all of them sata ports is to replace my sata m.2 into a pcie m.2

Unless I misunderstand how your motherboard works, it would seem so, yup.
