After backup you might try running;
chkdsk /r
from the recovery console command line. (/r implies /f and /p)

To start the Recovery Console, start the computer from the Windows XP
CD-Rom. At the "Welcome to Setup" screen. Press F10 or R to repair a Windows
XP installation, and then press C to use the Recovery Console. The Recovery
Console then prompts you for the administrator password. If you do not have
the correct password, Recovery Console does not allow access to the
computer. If an incorrect password is entered three times, the Recovery
Console quits and restarts the computer. Note If the registry is corrupted
or missing or no valid installations are found, the Recovery Console starts
in the root of the startup volume without requiring a password. You cannot
access any folders, but you can carry out commands such as chkdsk, fixboot,
and fixmbr for limited disk repairs. Once the password has been validated,
you have full access to the Recovery Console, but limited access to the hard
disk. You can only access the following folders on your computer: drive
root, %systemroot% or %windir%
