After updating my Catalyst drivers to 6.9 (and then also trying 6.10's that came out yesterday), and updating my DirectX 9.0c to the Oct update, I am immediating experiencing "Write errors" from one of my hard disks. Happens when running either FS9 and FSX. I think it reports the error comes from "harddisk volume 14". So a couple of questions.1. How can I determine which of my hard disk is Volum 14?2. There is a way to turn on and off "writing" (called caching?) if I remember... just can remember how. If it is a flaky hard disk maye I can shut that one off.3. Would latency have anything related to this? Maybe I could go back and adjust that? Maybe AGP Aperture too?Any ideas?

Hey again Clutch, this sounds like a known ATI driver bug I've come across. Seems the priority settings for system memory are changed or set to system cache instead of being dedicated to programs in the device manager. Open device manager > advanced tab > under performance choose settings, then advanced tab and set "Memory Usage" radio button to performance and see if this helps.I ran across this on ATI's site in troubleshooting section and will try and hunt the page up if it doesn't work out.Regards, KendallDell 8400 3.2 GHZ H.T.800 FSB/2MB L22 GB 533 DDR2X800XT 256MB/Catalyst driver - 6.9's6x Adaptive AA/16x HQ A/FIntegrated SoundDual Monitor: Dell 2405/1905CH Yoke/Pedals

Hey Kendall,Thnks for the tip. I opened it up and the radio buttn was set to "Let Windows choose...blah...blah", so I switched it to performance to see if there will be improvement. Haven't tried it yet but will give er a go later. ;)
