At least in CE's case, yes.  I recommend following existing Window practice /
algorithms to create larger, more complex VSN's that, one hopes, will avoid the
pitfall of duplicated VSN's.  I recommend including all removable media (CD,
DVD, USB drive, share) in the VSN assignment process; either use one, if it
exists, or create one, if it doesn't.  


Background: CE creates one XML file per drive it scans, using the drive's VSN
as part of the file name (CV_VSNmsd...VSNlsd.xml).  Had the last drive scanned
just happened to have some charts in it, the "no charts found" message wouldn't
have appeared, only whatever was in the last drive.  As it is, the drive had
nothing, so the last XML file name, being the same as the others, including
filled files, were overwritten by the last, empty file, hence the error message
seen.
