Strage problem with HDD


I am having a problem with my machine it is a gigabyte X99-UD4 Motherboard. I am using a SSD for my system drive and a HDD for my data drive.

When I plug my Seagate HDD into the machine I can format the drive use it from the OS.

However I cannot boot into my BIOS. If I disconnect the HDD I can then boot into BIOS. Plug a different HDD in and I can get into BIOS.

Any thoughts on how to resolve this?

I am thinking what I have is a faulty HDD and need to replace it.

Also am using the latest BIOS and there are no BIOS updates for the HDD. Btw put the 'faulty' HDD on another SATA controller and same result - can't get into bIOS.

when I say can't get into BIOS I mean the machine comes up with a Black screen.

So any suggestions - I am interested to here what other people think?

I'd say you already narrowed it down to a HDD issue.  You can try another machine to see if you have the same issue.

If so, return the HDD for a replacement.

Have you got the latest BIOS on the motherboard?
Older BIOS can have problems when talking to newer drives, either because of the interface compatibility or because of the drive size.

Thanks for the responses - I can confirm I have the latest BIOS for the MB.
