??hope your help.
Did the Seagate 1TB work on it before?
If not check If you have the seagate as SATA II, i would think you would need to set it SATAI for that motherboard
Sorry.The 1TB is new,i can use 200G as SATAI on !TB befor,
I didn't find the document of setting the seagate as SATAI,
but i try to set the seagate as SATAI on 1-2,2-3,3-4,the motherboard
didn't identity the 1TB HD.
This BIOS isn't support the 1TB HD.
load the bios defaults, then try different IDE modes for sata drive (if available), one after the other.
worth a try.
