Windows 7 thinks the internal SATA hard drive is an external USB hard drive

hard driveusbwindows 7

I recently built a new PC and it works perfectly. However, my internal SATA 6 hard drive is being recognized as an external USB hard drive by Windows 7. The hard drive works fine, but it's annoying seeing the USB icon in the taskbar when I don't actually have any USB components connected…

Can anyone give me insight into what's wrong with my system, and how to fix it?

Your drive isn't being detected as a "USB drive", it's a device with hot plugging enabled (which USB devices also are). You can disconnect the hard drive by Safely Removing it and unplugging it while the computer is on.

My mainboard lets me turn this on and off for individual SATA ports. Some have a master switch for the whole SATA controller, and yet others don't let you toggle it at all. In this last case you can sometimes switch your SATA controller drivers to disable the feature, but it's not actually harming anything to have it on. Windows won't let you unmount your system drive because there are too many important files open and locked on it.
