Is UATA compatible with ATA ?

[Guest]

What does ATA and UATA mean. Is it the bus of the harddrive. I am trying to bye a harddrive for a ata100 motherboard but find so many different types. Help, I need the breakdown.

UATA means Ultra ATA, applies to ATA/66 and ATA/100, and indicates that you need a 40 pin - 80 wire cable.

I remember the time when the Quantum Fireball SE was introduced with Ultra DMA/33.
<font color=blue>“... The new protocol, called ultra DMA/33, is a Quantum-patented technology that the
company will license at no charge to peripheral and PC chip set vendors...” </font color=blue> <A HREF="http://www.intel.com/pressroom/archive/releases/ultra_pr.htm " target="_new">http://www.intel.com/pressroom/archive/releases/ultra_pr.htm </A>

But you know what, as I remember, that Ultra DMA, or also known as Ultra DMA/33 or ATA/33 </b>didn’t require a 80-wire cable</b>. So, I think the “Ultra” before “ATA” indicates nothing to cables…

Let’s check what others are telling us about UltraATA:
