Windows 7 HDD issue

[Sirius 16]

I'm in need of a computer-wiz here.

My laptop was originally delivered with Windows Vista, which I soon swapped for Windows 7 (32).

It all worked well except for one thing:

In the far right corner of my toolbar, where some of the launched programs icons are, there is an icon that says "safely remove hardware and eject media".

This one usually pops up when you have plugged in a USB-flash drive.

 

When I press it, it says "Eject Hitachi HTS543232L9A300 ATA device", which is my internal and only hard-drive.

Is there any way to make this go away?

Obviously, the system doesn't quite recognize my hard-drive, and thinks that it's a removable external HDD.

I have tried updating the driver, but it says that it already have the most recent one.

 

 

 

I've also tried searching around google, but I couldn't find any suiting answer.

This might help.

Thank you, stubbie.

 

Would be very helpful.. if it worked.

I tried following excactly what they put out, but with no success.

 

My harddrive's location is "Location 0 (Channel 0, Target 0, Lun 0", yet, when I put this into my command line:

reg.exe add "HKLM\SYSTEM\CurrentControlSet\Services\msahci\Controller0\Channel0" /f /v TreatAsInternalPort /t REG_DWORD /d 0x00000001

..and restart my computer, nothing has changed.
