Hi, Mick.
As Mike Hall said, Disk Management is the tool to use in WinXP. It replaces
several programs that we grew to know (and love?) in MS-DOS and Win9x/ME.
Disk Management now creates and deletes partitions (which we used to do with
FDISK) and formats them (which we did with Format.exe). It also assigns and
reassigns drive letters, which we used to do with Device Manager. There is
an excellent Help file available from Disk Management which explains many
things about hard drives and file systems. (One quick way to start Disk
Management is to type at the Run prompt: diskmgmt.msc)
WinXP (like other operating systems) has a built-in algorithm for assigning
"drive" letters to primary partitions, logical drives in extended
partitions, CD/DVD drives, network drives, etc. Left to its own devices,
WinXP will assign letters from scratch each time it reboots, depending on
the hardware configuration that it finds at that time, so adding or removing
drives or partitions can cause shifting of the letters. Disk Management
lets us choose our own letter assignments and uses those on future reboots.
As with DOS and Win9x/ME, the System Partition (almost always Drive C

and
the Boot Volume (where we keep the boot folder, usually \Windows; this may
or may not also be C

cannot be easily changed, but the other letters can
be shuffled to suit our own tastes. I like to keep my CD/DVD drive letters
at some distance from my HD volume letters, so that they don't change when I
add a new HD, but that is a matter of personal preference. (My DVD is V:
and the CD\RW is W:.)
