No E:(PQSERVICE or F: (SYSTEM RESERVED dirves on cloned C: drive. But it boots fine.

I cloned my old c:drive because of some issues it was starting to have. Used a USB cable connection for the new replacement drive, assigned it as G:drive, then performed the cloning. The cloning went perfectly. After the final shut down, removed the newly cloned drive from the USB cable connections, unplugged the old C:drive, plugged in the newly cloned drive, and left the USB Cable connections open (i.e. no drive attached). The system Booted up perfectly. No problem. The new drive is in place as C: and everything is cool. Happy camper here.

However. curiosity dictates this question. The old drive had E:(PQSERVICE) and F: (SYSTEM RESERVED) partitions on it. The newly cloned drive does not. Why is that? Why can the new drive function just fine without those seemingly important drives (Partitions)? Apparently they aren't need, so why were they there on the old drive?

Further confusing me is that after getting the new C: hard drive installed, I did a clone to my old external hard drive (connected via the USB drive cable). When done, I now see the E:(PQSERVICE) and F: (SYSTEM RESERVED) listed again. The are apparently on the backup external drive. So, again, what the heck are these things?
