Whats up guys, Hate to keep making new threads for issues, but when i'm unsure about something, i like to be sure, before taking the plunge. I've got my new SATA2 HDD, it's a 500GB Western Digital (5000AAKS). Since installing XP and optimizing my PC fully, i'm just not noticing any performance increase over my old 80GB SATA, in fact, it seems worse! Opening up simple files (Like My Documents) on the drive presents an hour-glass with at least a 1 second delay or so before the file opens! Deleting tiny files of around 8MB sometimes brings up the progress bar? This is a fresh format, with nothing but maintenance programs, registry optimizers, diskeeper, and a couple of games on it. I've optimized XP to the fullest, and the HDD is always defragged, including the page-file. The HDD should not be as slow as it is im sure of it. So i think, maybe, i did something wrong, or there is something i need to do. One thing i haven't installed yet, is the 'SATA RAID drivers' from Gigabyte's website. Should i? Should i be running the HDD in AHCI mode instead of the generic motherboard IDE mode? If so, would it really require me to completely re-install Windows with a boot-disk containing specific drivers? The manual is a little hazey in this regard. I have the latest Bios already installed and all other motherboard drivers too. Here is my motherboard page. The Gigabyte site is SO slow for me, a real pain in the ass. Hope it isn't for you to! Input, thoughts, criticism, help appreciated. Thanks, Hux.
