I found this by searching Goggle. Does it sound safe for XP SP2?

Although not a direct answer to the question, proper setup can help guard
against such a problem. By partitioning a single physical drive into two
logical drives, you can place all of your data on the second partition,
leaving only Windows and other program files on the first partition.
Of course, Windows 2000 and Windows XP both store user information in the
Documents and Settings folder, which is place on the C: drive by default.
By
moving the Documents and Settings folder to the second partition, usually
the D: drive, you can keep your data segregated from Windows so that you
can
reformat the C: drive without worrying about losing your data (this does
not
reduce the need to maintain a separate offsite backup).
Here's how to change your Documents and Settings folder to another
location:
1. Boot to Safe Mode and sign on as Administrator.
2. Create the folders D:\Documents and Settings and D:\Documents and
Settings\username. (Replace "username" with your Windows XP username.)
3. In a Command window, go to the C:\Documents and Settings\username
folder
and type this command to copy all the folders and files to the new
location:
xcopy /e /c /h /k /o /x " newpathname"
Replace "newpathname" with "D:\Documents and Settings\username" or
wherever
else you want to put your documents and settings. If you are moving it to
a
FAT32 partition, leave out "/o /x". (You can type "xcopy /?" to see what
the
switches mean.)
4. Run Regedit and change the value of
My Computer\Hkey_Local_Machine\Software\Microsoft\
WindowsNT\CurrentVersion\ProfileList\userSID\ProfileImagePath
to the path of the new folder. Replace "userSID" with the user's SID --
look
at the current value of ProfileImagePath to tell which is which.
Obviously, back up your Registry before making this change, and don't try
it
if you are not familiar with editing your Registry.
Once you've got your Documents and Settings folder on D:, you can back up
all your documents and configuration settings (for programs and Windows
itself) by backing up all the files on D:. And you won't waste backup
space
copying program files, which you can always reinstall from
CDs................Jeff
