unenlitend

i have a custom built computer that i have been using the last few years, comprised of an ECS RS482-M motherboard, an AMD Athlon 64 3700+ processor, 2GB RAM, 1 300GB SATA/300 Seagate ST3300622AS-RK hard drive with Windows Vista 64 sp1 and installed programs, 1 300GB SATA/150 Seagate ST3300831AS-RK for data.

my problem is that with this setup, i haven't seen a transfer rate between the two hard drives exceeding 15MB/s...far lower than the 150MB/s maximum. sadly, the motherboard manual doesn't give nearly enough information for me to ensure that i have everything setup correctly.

in the BIOS, i have both hard drives set to IDE mode, which is the only way i could get the motherboard to detect and initialize them. when trying to configure a raid setup, i get an error stating that no raid devices can be found.

i only have the ATI display drivers installed automatically by Windows Update, every time i try to install the full driver package from ATI's website i get an error relating to the southbridge drivers and a missing .inf file. after some research i am fairly sure this could have something to do with the problem, but i haven't been able to get the driver to install properly since ATI first released 64-bit drivers for my video card. despite this failing during install, i have no errors or issues reported in Device Manager, let alone a device missing drivers.

at this point i'm stuck and no longer no where to go, any advice would be greatly appreciated.

thankyou,
scott
