I have emailed Toshiba (TAEC_SPBU_techhelp@taec.toshiba.com) and will post their reply, if I get one.

In the mean-time, if someone at ASRock could confirm the issue, give me any advice or a new beta BIOS to try that would be great.

Please try to connect one HDD at a time and add another if the system detects the HDDs properly. If the problem persists kindly try to connect the 2 pcs of HDD per one SATA power connector to see if it will work. Also, kindly try different SATA cables. With thanks, ASRock TSD

Hi, thanks for the reply.

I can confirm that:

1. Replacing *ALL* the SATA cables with brand new cables has no effect, same problem.
2. Using each drive by itself, one at a time, on port 1 has no effect, drive not detected.
3. Using each drive by itself, one at a time, on port 2 has no effect, drive not detected.
4. Using each drive by itself, one at a time, on port 3 has no effect, drive not detected.
5. Using each drive by itself, one at a time, on port 4 has no effect, drive not detected.
6. Using pairs of drives, on port 1 and 2 has no effect, drives not detected.
7. Using pairs of drives, on port 3 and 4 has no effect, drives not detected.
8. Using pairs of drives, on port 1 and 3 has no effect, drives not detected.
9. Using pairs of drives, on port 2 and 4 has no effect, drives not detected.

For the above tests, the unused drives were not connected to the SATA POWER *and* DATA.

What firmware does you drive have? Is it the same as mine?

I also note that adding the NMVe to 5 port SATA adapter, as seen in the photo, had no effect on the cold-boot detection. This adapter was only installed *after* the original problem and is used for connecting additional storage devices (1x SSD + 1HDD).

I repeated the tests with it removed and there was no change.

Dear Dominicc,

Thanks for the reply.

The Toshiba HDD that we tested is also FW0101.

We have some more suggestions for you.
1. Please refer to the page. 21 to clear the CMOS.
   https://download.asrock.com/Manual/Z490M-ITXac.pdf
2. Please remove all of the storage devices only install the one Toshiba HDD and try.
3. If possible, please try with a different power supply.

If the problem persists, kindly contact the store where the motherboard was purchased for further assistance.

With thanks,
ASRock TSD
