Hi There ,,

I Have A Seagate Barracuda 2 tb

And I Was Running On IDE Sata Mode

And The Burst Mode On Hd Tune Was About 330 mb/s

But After That I Heard About AHCi And Its Better Than IDE

So I Swtiched From IDE To AHCI

And Reinstalled The Windows 7 64x Again

but When I Made A New Test With Hd Tune

Burst Rate Scored Only 230 mb/s

What Is The Problem I Have Got ??

Odd that it is faster under IDE then AHCI. AHCI enables NCQ (native command queing), hot swap capability, and a few other advanced features of the drive. It's also generally faster or equal to the older IDE mode.

You may to try a utility other than HDTune just to verify the numbers. You can find HD TACH at several locations online. ATTO is also pretty good.
