I was wondering if I could get some help/advice here. I've modified my old system to include a GA-965P-DS3 m/b (Rev1.33) and have two SATA drives installed - a Samsung 250GB drive and a WD 1TB drive. Now I'm having some troubles getting the 1TB drive recognised under XP Pro. I've updated the BIOS (Revision F12 from the Gigabyte website) and have installed all the latest drivers. From an initial cold boot, the 1TB drive isn't recognised by XP. Subsequent boots seem to fix the problem and the 1TB drive is available in XP. Any ideas as to what's going on? Am I missing something? The BIOS recognises the 1TB drive okay. Any help/advice would be much appreciated. Thanks.
