I just got my spare machine up :
MOBO gigabyte GA 945g-zm-s2 rev 3.0
D-820 CPU
1gig Dual channel ddr2 533 2 sticks 512
wd SATA 3.0 320 HD
Nec DVD bURNER
Winxp pro sp2

It has the ich7 chipset which I thought was SATA 3.0
I went to intel got the floppy install, did the F6 when installing used the ich7 ahci driver.
It installed windows XP Pro fine.Under device manager it shows the correct SATA controller ,but under primary ide it is listed as udma 5. I have the bios on Auto for configuration of SATA, I have tried every bios setting enhance, combined. non combined and even turning off PATA. How do I get SATA 3.0 to work? I even tried the intel storage matrix software it wouldn't install. Help!
 
is there a jumper on the drive that has to be removed? My seagate 320gb 7200.10 came with a jump which forced it into sata 1, once i removed it windows recongnized it was sata 2 or 3.0gbs. HDtach also got a boost in burst speed rate.

This is correct and how it should appear.

Your drive is operating in UDMA5 (ATA100) mode which is the highest that drive supports.

Although the Serial ATA interface comes in 2 standards (SATA 1 which is 150Gb/s and SATA 2 which is 3.0 Gb/s) these are interface standards and are still based on ATA. Your hard drive is still IDE and as such follows the standard transfer mode rules. UDMA5 (or ATA100 - 100MB/sec) is the highest many IDE hard drives support. Newer SATA drives SHOULD support UDMA7 (ATA300 - 300MB/sec) but it may take some finagling to get working (or may not work at all) on certain chipsets/controllers

Short answer: Don't confuse the interface standard/bus with IDE transfer modes.
 
So by just changing the interface method and not the actual drive itself any HD manufactor can claim SATA 3.0. ? How would you know if the drive was a true SATA 3.0 drive?
I am looking at the WD box and it does say 300 MB/s if the drive can only function as an ATA 100 than isn't that false advertising?

Personally this is BS sounds like another piece of marketing hype to sell more old tech HDs to an unsuspecting user. This whole concept reeks of being a sham.

It makes the only good thing to me about SATA is the simplified cabling.
 
Another interesting thing I just noticed. if I run HD TACH I get 126 meg tranfer rate. If the drive is truly UDMA 100 than how can the burst rate exceed the ATA standard?
