[SOLVED] Asus Rog Strix X570-E What SATA ports are disabled when using an M.2 drive/card?

[pats2265]

I think I have the answer, but didn't find this question or answer when searching so I'm adding it to help others.

I have an Asus ROG Strix X570-E MOBO, and an M.2 card. I've heard that on some MOBOs if you use an M.2 card you loose two SATA slots (this is what I've been told not read).

So my question is what two SATA ports are disabled when using an M.2 drive/card?

After I added my M.2 card, and booted, the BIOS has not disabled any of the 8 SATA ports.

I've read both the SATA and M.2 sections of the MOBO manual, and neither section say anything about SATA ports being disabled, so my current belief (based on the manual and the BIOS) is that NO SATA ports are disabled when using one or two M.2 cards on the X570-E MOBO.

Your board's manual and the specifications listing on the board from the manufacturer's site does not stipulate SATA ports being disabled when populating M.2 drives in their respective slots. Furthermore, page 1-7, in your manual states how many lanes are allocated to each slot/device when having multiple slots and devices populating the board.

There are B450 chipset boards that have a random number of allocations to SATA and M.2 ports. One example is the TUF B450M-PRO GAMING from Asus that loose SATA ports 3, 4, 5 and 6 when you populate 2 M.2 devices on that board. It's stated in the manual and prior to that, on the product's specifications page.

The x570 chipset has access to more pcie lanes, thanks to using pcie4 instead of 3.

Most boards I've seen will let you use one, if not two, m2 slots with no penalty to SATA ports. A third slot being populated may lead to losing two SATA ports.

That might not be true... I have a ASUS X570 ROG Crosshair VIII Hero... I unknowingly connected my hard drive on SATA ports 7 & 8. My NVMe M.2 SSd took over a minute to boot. After reconnecting the hard drive to ports 1 & 2, my boot times dropped to 30 seconds...

I having the issue here when I newly plugged HDD to the sata port which originally I had the nvme ssd with window installed. The HDD shows as disk 0 even put in port 3-4-5, and bios keep prompt smart predicted error on hard disk, are this two related? How should I change the HDD to disk 1 instead, which may help to overcome the failure?

Is it a new hard drive? Did you initialize it using Disk Management? Likely the drive is bad if SMART is showing errors...

Hi Jon, yes, it was a completely new HDD. The first boot is fine, then allocate the disk using the disk management, things going fine and smooth until I restart the PC, the SMART showing the error. Then I delete and formating the HDD or relocate to other SATA port, it is still the same.

I just called the seller and they ask me to bring over the whole system for them to check. They only willing to replace is the HDD is bad. But what if the HDD is good, what's wrong the motherboard? or the SMART?
