Hi

I have a SATA drive

Shoudl I installed it as ACHI ?

What advantages does this have over installing it as an old style PATA?

I have an WD 500GB SATA drive and a Gigabyte DS3R.

I note on startup the SATA controlelr takes a whiel to find the SATA HDDs - I wonder if I coudl avoid this if I set it up a an old PATA drive - wil lI notice a difference in speed etc?
 
There aren't a lot of advantages in using AHCI. It's designed to allow certain SATA features like NCQ and hot swapping through a generic driver similar to that used for ATAPI devices at the moment. Neither NCQ or hot swapabiltiy are must haves for internal desktop devices.

Personally I'd leve the SATA controller set to legacy IDE mode, there's no performance impact and it's just less hassle.

As for the time it takes to detect the drive, which SATA controller are you using (that board has 2)?

A GIGABYTE P35C DS3R - I THINK it has 2 - only because it mentions in the booklet that there is a GB SATA contorller on there as well.

I am only using one of the huge nubme rof SATA ports it has anyway.
 
If the system is only detecting the HDD right at the end of the POST then it sounds like the drive is on the JMicron controller. If you can move it to one of the Intel ports then you'll be able to disable the JMicron ones and hence speed the boot.
