M.2 and Sata port

Im having 500gb 960evo ssd and 4 sata slots in my pc in which one of them uses my 1TB WD Blue(sata 1). I was looking at my motherboard manual and motherboard site to see how many sata ssd i can add in future but i cant find the info how much sata ports are disabled cause of my ssd. Motherboard is MSI B350M Mortar

Usually, or totally, two SATA ports are disabled once an M.2 driver (I assume Intel Optane, for instance) or storage is used.

M.2 is a formfactor. It can be both SATA and NVMe (PCI 3.0 x4).
With the use of a 960 (NVMe) normally disable 2 sata ports. only the manual will tell you which ports.

depends on the mobo, read its manual to see whats disabled when sata or nvme drive m.2 is used

Nothing I can find in the manual states a M.2 Drive affects the Sata ports in anyway. My board has 6 Sata ports and that leaves me with 4 as ports 5 and 6 are disabled. I suspect you have full use of all 4 Sata ports as the M.2 has dedicated lanes not linked to them.

To be sure contact MSI. Alternatively and Faster than contacting MSI just move your 1TB HDD from Sata 1 to the other Sata ports. Then boot after each and see if it shows up after each change.

Checked the manual myself, it's not mentioned anywhere, so no ports will be disabled when using the M.2 drive/stick.

If they had added that feature, you probably would have had 6 physical SATA ports instead of the 4 you have now.

960EVO is a NVMe drive, it does not use SATA interface. It will not interfere the SATA ports whatsoever.
Only if you install a M.2 SATA drive, then on some motherboards it will disable a SATA port.

Nope. Whether it's an M.2 SSD or PCIe SSD can affect use of Sata ports as some boards share the lanes.

Copied this from my Motherboard, GA-Z270X-Gaming K5, manual.

Installation Notices for the M.2 and SATA Connectors:
Due to the limited number of lanes provided by the Chipset, the availability of the SATA connectors may be affected by the types of device installed in the M2M_32G and M2A_32G connectors. The M2M_32G connector shares bandwidth with the SATA3 4, 5 connectors. The M2A_32G connector shares bandwidth with the SATA3 0 connector. Refer to the following table for details.

Oops, forgot about the case of multiple M.2 drives. OP only has one NVMe drive, it shouldn't disable any SATA ports.
