Windows XP defaults to using the highest available drive letter when you
manually map a drive. Using logon scripts a network admin can use any drive
letter they want. The user also has the option of picking any available
drive letter when mapping a drive manually. Most network admins are slowly
switching to the XP default scheme as it alleviates conflicts with external
devices which are becoming more common. Starting at F: is a carry back to
early Novell and Banyan days when DOS was the OS. Back then it was very
unlikely a pc would have more than three storage devices installed. As time
and hardware progressed network admins started moving the starting point up.
It was also common for a while (again with Novell mostly) to use things like
S: for a searchable drive, P: for programs etc.. Many network admins grew up
with these old schemes and have never changed.
In the end it is a matter of personal preference as it is possible to change
drive letters as needed. I have found letting Windows use the lowest letter
and up for external media, map network drives from the highest letter down,
and use middle letters for special purposes to work well in almost all
situations.
