Question Why my Motherboard not detecting any of my hard disks?

[souravsaseendran]

I just installed a new M.2 SATA SSD and installed Windows 10 in it. After that it doesn't detect any of my three SATA hard disks not even in the BIOS. It doesn't showup in diskmanager as unallocated or in any way. I have tried all the ways of connecting. In other computers it works well. Only in my PC it doesn't showup anywhere. The drive is not faulty. And my cables and ports are well working just before im installing OS into new M.2 SSD.

Motherboard: ASUS B350-PLUS
Processor : AMD Ryzen 2400G
New SSD : WD 250GB Green SATA SSD
Operating System : Windows 10

Old Hard Disks that are not showing:
1. Seagate 2.5" 500GB
2.WD Black 3.5" 160GB
3. Hitachi 3.5" 250GB

Well sounds like one of two things.

Drivers and or BIOS running type. Are you running your BIOS in UEFI mode? What BIOS version are you running? it could also be an out-to-date BIOS.

When sata M.2 device is installed, ports SATA6G_5 and SATA6G_6 get disabled (group of separate 2 SATA ports).
Move your sata devices to different sata ports (to group of 4 SATA ports lower part of the board).

Is the Bios is Raid mode ?
