I recently purchased a Gigabyte x58A-OC Motherboard REV 1.0. I just built a pretty hefty gaming rig and when I finally went to install the 3TB Hard drive using WIN 7 Ultimate 64 bit the installation would only recognize 2 TB of the Drive and would continue to dismiss 900 GB of the remainder. I installed the OS and sure enough it's showing I have 1.99 TB of my drive with a 100MB system partition and 900GB unaccounted for.
I read a few internet blogs about how this was an issue on "older" BIOS versions of some motherboards failing to recognize anything past 2.2TB of Hard Drives as the 3TB are a recent addition. I thought it might be a WIN 7 error but it looks like it's the BIOS and I'm unsure how to correct this and I was unable to discover an update for the BIOS ( I don't think there is one yet though Gigabyte does currently have a BETA BIOS flash out).
Has anyone else had this issue or know how to resolve it?
