From: "Chris Antos (Exchange)" 
there is a Win32 API, "SetVolumeLabel".  here is how to use it from TSE:
dll ""
integer proc SetVolumeLabel(
		string RootPathName:cstrval,
		string VolumeName:cstrval) : "SetVolumeLabelA"
integer proc DeleteVolumeLabel(
		string RootPathName:cstrval,
		integer MustBeZero) : "SetVolumeLabelA"
// yes, "SetVolumeLabelA" is correct for both the functions, it is not a
typo.
end
example:
proc Foo()
    SetVolumeLabel("C:\", "DRIVE_C")
end
here is the documentation from the Win32 Programmer's Reference (edited
slightly by me):
-----
The SetVolumeLabel function sets the label of a file system volume. 
integer proc SetVolumeLabel(
    string RootPathName,	// address of name of root directory for
volume 
    string VolumeName 		// name for the volume 
    );
Parameters
RootPathName:
	Points to a string specifying the root directory of a file
system volume. This is the volume the function will label. 
VolumeName:
	Points to a string specifying a name for the volume.  [To delete
the label from a volume, call DeleteVolumeLabel(RootPathName, 0)].
Return Value:
	If the function succeeds, the return value is TRUE.
	If the function fails, the return value is FALSE. To get
extended error information, call GetLastError.
