Does someone have a Segate 500GB 32MB Cache drive using P5WDH Deluxe with 2504 bios ? the hardisk has S015 Firmware, so it does not have the Cache problem.

because when using AHCI and with Intel Matrox manager driver the Hardisk freezes when trying to copying to or copying from this hardisk, in XP it works without a problem. and all other hardisk does not have problems, and my friend bought the same hardisk with me in the same time, i dont think it a hardisk fault because it works nore to do with AHCI. but he has Gigabyte DQ3 P35 chip and he uses AHCI without a problem. What could be the mainfest here? he uses Vista 64bit too.

only in Vista 64bit it freezes and i need to restart using the reset, the hardisk shows Steady L-e-d without flashing it just glow without doing nothing. but i cannot close the copying windows or extracting windows from winrar or whatsoever.
