Windows 7: Why won't my external hard drive work in IDE mode through eSATA?

Why won't my external hard drive work in IDE mode through eSATA?

My motherboard is ASRock m3a770de. I built my machine 3 days ago. I have one Hiatchi 500gb internal HD, and one 1TB external HD.

I am running Windows 7 x64 Ultimate Edition.

After building my computer three days ago, I installed windows, and my external was not being detected through eSATA in the BIOS or in Windows "Probably need to install drivers" I said.

So I put in the CD that came with my motherboard, and installed the AMD All in One Driver that was on it. Restarted, and hey, my external was showing up.

Today, after installing SP1 (not sure if thats what did it), my ext hd was no longer showing up again. I reinstalled the driver on that CD. Now, I'm not sure if it even installed the first time, because it said it was currently uninstalled through the ATI catalyst installation program. But it didn't work this time. I'm not sure what got it to work the first time. But my eSATA drive was being read in IDE mode for three days. When trying to get it work the first time, I did plug it in via USB to see if it would work, maybe that had something to do with it working the first time?

Anyway, I changed my registry to start up in AHCI mode, and then went into my bios and changed my storage config to AHCI. Upon booting, windows would not load with my external HD turned on (anybody know why?), but loaded once I turned it off. Windows then installed AHCI drivers, and upon restarting, both hard drive, external and internal, were being detected as removal storage.

Why can't I get my external HD to be read in IDE mode through eSATA? IT doesn't get read through the BIOS or Windows, even if i scan for new hardware.

EDIT: sigh, now when I just went to reboot, it wouldn't load windows when my external hard drive was plugged in. Windows loaded when I unplugged it. Windows detected it when I plugged it back in.

I never had the slightest issue with eSATA in Windows XP. What's the deal?

Check your boot order, sounds like you system is trying to boot from the external drive.

Can't do that. When the external hard drive is connected, I can't even access the BIOS; no command goes through. Not boot menu, bios, etc. It just freezes before Windows boot. If I plug in the external hard drive, then enter the bios, it just goes EXTREMELY SLOW. this is when in AHCI mode. In IDE mode the external doesn't even exist in bios/OS

EDIT: Also, I'm realizing that Windows won't shut down if the hard drive is plugged in / detected. I have to turn it off. Now I can't even get it to be recognized in AHCI.

I just want to use eSATA. I was excited about having eSATA ports right on the motherboard. This sucks.

Can you fill in your 'System Specs', lower left corner of any of your posts.
Looks like a driver/BIOS or hardware issue.

Have you updated drivers from your motherboard web site?

What BIOS version are you running?

Did you have your external connected when you installed Windows 7?

I updated all of the drivers.

I'm running the latest drivers.

I did not have the external connected when installing 7. Didn't think that would be a problem.
