I have an old computer and want to upgrade the hard drive..it runs on an intel 810 chipset and the specs say the chipset supports ide controller ata/66...can i use a ata/100 hard drive, or is there a way to make the computer use a ata/100 hard drive...also how big of a hard drive can i use..i tried looking up the motherboard but it is so outdated there are no specs on it anywhere..any help would be great
YEah, you can use it, Backwards compatible, but you will lose a substantial amount of speed. Get an ATA100/133 controller card. Plugs into your PCI slot, and you can have up to 4 additional drives with it. That will also boost you to ata100.
