New SATA HD causes POST 75
What to do?
Thursday, April 10, 2008 by thomassen | Discussion: PC Hardware
I bought an extra 500GB SATA HD yesterday and a SATA DVD drive.
My MB is an Abit AN8 32X.
I plugged in the new HD and replaced my old IDE DVD driver with the new SATA DVD drive.
Everything went fine the first boot.
DVD drive worked fine.
I used Windows' Disk Management to Initialize and format the HD. (I choose GPT instead if MBR when I was asked to initialize the disk)
When I was done I shut down the computer and went to bed.
Today, when I booted up the computer, it stopped with the BIOS screen.
When I view the POST messages it halts after it's detected all the drives and the MB displays POST error 75.
I unplugged both the new drives and the computer booted.
When I plugged in the DVD drive it still booted.
When I plugged in the new HD it stopped again.
I unplugged the SATA cables and plugged them in again. Still stops.
I swapped SATA cable with the new HD and the DVD, still stops.
I've tried plugging it into different SATA ports, still stops.
I don't understand why the HD suddenly stops the boot process since it worked the first time I booted it. Does it got anything to do with the initializing?
I tried googling for the problem but couldn't find anything that'd sort out my problem. Some place said that you could get an POST 75 if the HD was too large for the MB. But surely my Abit AN8 32X isn't that old?
There is one thing I just thought of when I type this. My new HD is connected to the same power cable as my first HD. Could this be an issue? Currently they are still plugged in on the same power cable, I've just removed the SATA cable so I could boot the system again.

If your BIOS does not support GPT then you shouldn't select that. In fact most BIOSes don't support it, except for MAC and some high end servers and workstations.
I suspect you need to do MBR instead.
