|Files deleted from a NON-System drive do not go to the Recycle Bin.|
Not true, if the partition resides on a local hard disk deleted files *normally*(as per default settings) end up the recycle bin regardless if they are system, primary non-system or logical drives. Unsupported file systems being an exception.
Each local disk normally houses it's own "recycle bin" of deleted entries in a hidden system folder "Recycled" on the root of the disk.
Removable drives are a different matter, in my experience deleting files off usb flash drives is permanent under windows xp(could be mistaken), but that could change in the future with the way capacity is always increasing.........
It's hardly relevant but files deleted via the cli also don't seem to go to the recycle bin
