Question Gigabyte GA-Z97X-UD3H cannot boot in AHCI mode if HDD initialized (in GPT or MBR)

[Tacis]

Hi.

I have Gigabyte GA-Z97X-UD3H motherboard and I purchased a WD HC310 (0B35948 HUS726T4TALN6L4) HDD.

If I initialize disk in GPT or MBR, I cannot get through POST in AHCI mode. IDE and RAID mode let the POST pass, but not the AHCI mode.

What can I do to fix this?

Just to save time on what has already been discussed on different forums. No need to repeat all of that.

Solved (but needs some clarification)

DON'T TRY THAT IF YOU HAVE ANY CRITICAL DATA ON THE HDD! ALWAYS MAKE A COPY OF THE DATA!

After initialization (and any further creation of volumes, copying files etc), but BEFORE the reboot, open a hex editor, in the editor - disk and delete (fill with "00") from offset 0x1000 to 0x1060. Save, reboot.

After reboot this data is recreated, but it doesn't make the POST of Gigabyte GA-Z97X-UD3H freeze.

DON'T TRY THAT IF YOU HAVE ANY CRITICAL DATA ON THE HDD! ALWAYS MAKE A COPY OF THE DATA!

P.S. Can anyone, please, explain, what is this at offset 0x1000-0x1060? How could it freeze POST in "BEFORE" state? What happens after I delete it and reboot? Why is it recreated differently (and doesn't freeze POST)?
