Some possible info...

[Flipe]

Kernel for the zune is loaded from :
E:\pyxis\main\platform\pyxis\target\ARMV4I\retail\ kern.pdb
I think....

Pryxis, is a rumored Project code name for zune

BetaNews also has some more code names from Project Argo for us to kick around: Pyxis and Alexandria.

-from engadget.

A .pdb file is a program database file. However I dont quite understand the E drive.

Firmware has traces of Stylus Background

"Carefully press and briefly hold stylus on the center of the target.-Repeat as the target moves around the screen.Press the Esc key to cancel."

After all this...
What are the blank files in the zune storage directory? (All are blank)
Where is an E:/ drive?

> A .pdb file is a program database file.
Correct. They are leftover debug info pathnames left in the image.
When the debugging information is present, these pathnames are used by the developer during debugging
(obviously compiled on a machine with an E:\ drive)

They are not useful in a retail build.
They are a good hint at what parts are standard (E:\pyxis\main\public\cebase\cesysgen\oak\...) and what have been customized for the pyxis (Zune) platform (E:\pyxis\main\platform\pyxis\target...)
