Strange "safely remove HDD" problem

Hi, I've got this strange problem in Windows 7 RTM x64 - all the time when I click the "safely remove" icon in taskbar I can see both my hard drives in there, so it's easy to remove them just by clicking on them. That should not be possible afaik! The system disk couldn't be unmounted just like that. I've seen couple of times, when the second drive with movies and stuff just wasn't in "My computer", sister probable unmounted it instead of her flash drive.
So the question is, how to prevent showing these drives in "safely remove" option? I got the Asus P5K Deluxe motherboard, both of disks are connected to the south-bridge SATA connectors, working in AHCI mode (NCQ is a good thing, right? :) )
Thanks for any help

I've already used latest Intel chipset/inf update package, but the problem is still there. That's strange

On my system, if I have the SATA controller set to AHCI mode, the hard disks show up as removable.

I think that they really are removable, or would be if they were in hot swappable cartridge mounts. (The OS drive can't be removed, as it is always in use.)

Yes, bobkn your correct, thats what hot swapping is, and its the same on mine.

So it's a feature, not a bug. But the question remains, is it possible to use AHCI and disable hot swapping on system drives?

No I don't think so - just don't use it thats pretty simple - funny most people want it enabled these days with external hard drives - you can change to sata as IDE in the bios, but you would need to reinstall the OS - as it will BSOD otherwise when you try to boot.

u can change from ahci to ide without fresh instal
and back again... i did it myself through the registry but i do suggest u only do it if u know what ure doing!
but i dont remeber how i did it... the trick was to do it in the registry first then restart then before it boots into windows... get into the bios and change that to ahci... it took no longer than 2 mins to but i cant remember what the reg key was... if u need it PM me as i said going into the registry is for more experienced users... if u dont know what ure doing u will crash ure PC!

It's not because of me, but my younger sisters often use the safety remove feature for removing flash drives an sometimes, they unmount the inner hard drive, true story
