I cannot run 4 SATA hard drives at the same time.
One of the 3 HDD disappear in Win10.
But, if any three HDDs can work fine until I connect another one.
Please help me!

you need to switch your OS to UEFI mode

MBR has a partition limit

Dear Aerius,

Greetings, this is ASRock TSD.

Referring your question, we have confirmed that it can work properly with 4 hard drives.
Please refer to our test result as below link,

So we provide some suggestions for verifying:

1. Please plug two HDD separately. (Do not connect 4 HDD in the same power cable)
2. Please clear CMOS and verify again. (Make sure to unplug the power cable)


All the best,
