Don't bother with ATA/100 if your OS is Win2K...

I found this interesting little tidbit of info on TechNet today, while I was searching for info on optimizing ATA/66 in Windows 2000:

http://support.microsoft.com/support/kb/articles/q260/2/33.asp

The important theme of the article: "Windows 2000 does not support ATA-100 (Mode 5) for IDE hard disks. All ATA-100 IDE hard disks that are used with Windows 2000 default to ATA-66 (Mode 4)."

This is interesting because the same page also posts a hotfix, but it seems to be pre-SP1. But what is the hotfix supposed to fix anyways? It doesn't mention. Also the version numbers conflict with the files from SP1. Maybe someone wants to install it and see if there's a performance gain on ATA66 or ATA100 hard drives.

Here is a site with an ATA66 tweak that contradicts Microsoft:

Scroll down to "UDMA66 All The Way".

Has anyone applied and tested this tweak? (before and after, using benchmarks?)

Very interesting, seems odd that a hardware item is dictated by software settings... I have doubts. I thought the UDMA/DMA and ATA/66 and ATA/100 where sperate entities?...
