Is everyone with this issue running Windows 7? I had been running Vista for couple years and it was going great. A couple months ago I had upgraded to Windows 7. When running under Windows 7, I had noticed this issue. I also had noticed it when running The Last Remnant with Windows 7 Release Canidate and Server 2008 R2. I currently have Vista and 7 installed (both 64-bit). I can bounce between the two, using the same settings and Windows 7 will have HD thrashing when the game first loads up. Once things start getting cached it's fine. I've tried using the same chipset and AHCI drivers in Vista and 7, but 7 continues to have problems while Vista is fine. No other game or program seems to have a problem. They test about the same using HD Tune. I think there's an issue with FFXIV and Windows 7. I've tried a bunch of different options and drivers and nothing is fixing the issue.
