Well the key thing is what happens when you try to access drive D by double clicking? Does it access it or do you get an error? That information would help alot.
Seems that SATA drives plugged in during a clean install get considered removable, but after that they don't..??
It's also just interesting to me that as of now 1 of 3 SATA drives is showing up as removable. Why that one?
Is there any difference between the SATA ports they are connected to on the motherboard? For example, one connected to an Intel SATA port, and the other 2 to Marvell SATA ports.
If so, see if having them connected to the same type of ports as the one showing as removable.
