I'm busy upgrading the hard drive on a system with a Gigabyte GA-GC230D motherboard with an Atom CPU.

I am swapping out a 120GB SATA drive with a 500GB SATA drive. Both notebook form factor. Both known good. For some reason the BIOS recognises the 120GB drive but will not recognise the 500GB drive.

I just can't think of a reason why it wouldn't. The new drive is a Hitachi 7K500.

Sometimes its just a compatibility issue, another brand may work, did you update the bios on the motherboard? – Moab Dec 20 '10 at 11:07
    
One reason can be SATA1/SATA2 negotiation. I'm not sure of specifics, but a motherboard SATA connector whose SATA controller knows only SATA1, will not be able to communicate with a SATA2 hard disk(unless the SATA2 hard disk is jumpered to act like SATA1). I am not sure if it's just a motherboard issue in that situation. And I don't knwo if all SATA2 HDDs have that option. – barlop Dec 20 '10 at 11:42
    
There is a flaw in the subject you gave your question. Your question may not be SATA specific. – barlop Dec 20 '10 at 12:17

  • Try to update motherboard BIOS to the latest version.
  • Try another SATA cable.

It was the cable. Thanks for the suggestion. – tomfanning Dec 31 '10 at 16:18
