I assembled my new PC, and sometimes one HDD is not recognized by the BIOS.

This is my setup:

- Asus z97-pro
- i7 4970k
- gtx 970
- 16gbs ram
- SSd
- 500gbs HDD
- 1TB HDD

This is what happens:

- turn on PC
- bios screen takes longer than usual to appear (after I press delete)
- bios appears and the HDD is not detected.
- if I ignore it, and load Windows (8.1) it takes longer than usual to boot, it takes approximately double the time. I think it's related to the HDD not being detected/problematic.

As a side note, in the BIOS, when I go to the boot menu and I click "boot list" or something like that, it does show me the missing HDD, however, when I click on it to use it for boot, I got a black screen, and when the BIOS came back my mouse pointer was static, I mean, it didn't move when I was moving the mouse.

I think it has something to do with the port, and not the HDD, because when I switched the HDD the other one had the same problem instead.

Any help is welcome!.

Hey Indiana. To determine if the HDD is not having issues for sure, then I'd recommend that you try it with another computer, backup any important data which you might have on it and run the manufacturer's diagnostic tool to test the drive and see if there are any errors or bad sectors. It might be the SATA cable as you said. If the HDDs have no trouble running on another computer, but keep having errors while connected to the same SATA connection, the issue is probably because of the cable. You could just replace it or use another one instead if you have any available.

Hope that helps.

Well it seems like this could have caused the issue. I've read about similar problems, sorry I didn't think of this from the start. I'd suggest that you use the Intel ones for now. Perhaps with an update of your BIOS this might be fixed, but if everything is running OK and you don't need them for now, I'd suggest that you leave it like this.

Your SATA HDD connection to the ASMedia SATA connector was definitely the problem. The ASMedia connectors are designed to handle storage devices, NOT a bootable drive. As a general proposition you should always connect your bootable disk containing the OS to the FIRST SATA connector on the motherboard which will be designated either as a SATA 0 or SATA 1 connector.
