如何清除SATA硬盘的“安全删除硬件”图标

百度以及中文网站上千篇一律的是NVIDIA的芯片组的方法，解决方法如下：

打开注册表,找到[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvata],新建一个Dword值,命名为"DisableRemovable",将"数值数据"更改成"1",最后重启一下,就好了。你用的是NVIDIA的芯片组，你安装了NVIDIA主板驱动中的IDE驱动，装了以后就会出现这图标。

可是大部分不是NVIDIA芯片组。

搜到http://www.overclock.net/t/974023/fix-ahci-sata-drives-showing-in-safely-remove-hardware，解决了这个问题。将方法贴在如下：

Ever since I set my BIOS to AHCI, I was plagued with my SATA connected drives showing up in the "Safely Remove Hardware" icon.

I understand that eSata, and USB devices should show up there. However, my internal devices, HDDs, CD/DVD/BluRay are showing up as well.

I didn't want to have to reinstall Windows 7, and set BIOS to SATA/RAID.
I wanted a better solution.
I found it!


This is a Registry fix.
You should ALWAYS back up your registry before you make changes - it only takes a second to do it, and if anything happens to it you'll need to reinstall...
Here we go...

Regedit your way to:
HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ services\ msahci
and create a new KEY called "Controller0"
inside Controller0, create a new KEY called "Channel0"
Now inside Channel0, create a new DWORD called "TreatAsInternalPort"
set this value to "1"
(this sets SATA port 0 (Drive C)to no longer show up in "Safely Remove Hardware")

Now, go back into the Controller0 folder again.
inside Controller0, create a new KEY called "Channel1"
Now inside Channel1, create a new DWORD called "TreatAsInternalPort"
set this value to "1"
(this sets SATA port 1 (Drive D)to no longer show up in "Safely Remove Hardware")

And so on, until all internal SATA ports are set to be treated as Internal.
My motherboard has 6 SATA ports, so I have set Channel0 to Channel5.

Here is an example of my registry change:

Your motherboard may have more or less SATA ports,

just remember to start with 0
6 Ports = 0-5 etc.

Now Reboot to allow changes.
