P8Z68 Deluxe Hot Plug (Safely Remove Hardware) Windows 7

I have just finished building my rig, and I since I have a case with a drive dock I was trying the hot plug feature. When I plug in the drive, it get recognized and works well but the drive is not listed under the safely remove hardware in windows. First the dock was connected the Marvell 6.Gb/S Controller (which I think is set work as AHCI, cause there's no option to change it). I went to the Marvell device property under policy and tried to disable the Enable Safely remove Option and re-enable it, but I didn't succeed. Then I tried using the Intel ports in AHCI while enabling the hot plug but nothing was listed, I have changed the Intel controller to work as RAID but I still had no success.
Last I decided to just unplug the drive, then I saw the IRST software pop up notice that the drive was disconnected. I have plugged it again, then unplugged, I had the same pop up notice. Did it 4 times, but the drive was never in the Safely Remove Hardware list.

Both my OS and Data drives where in my P35 built and when in AHCI, they used to be listed in the Safely Remove Hardware. my BIOS, OS, and all my drivers are up to date.

Now I am wondering if Is it safe to just unplug the drive that way.
