anyone help me?

So you used the Windows XP CD that came with your computer. Did you choose to repair or to install a new copy of windows XP? What is tha name of the file where it stops?

To see if your HDD is good, you can run Dell Diagnostics. Boot from the Dell provided Driver CD, the graphical diagnostics program will appear. Run all the HDD tests and see what it says.

Although I haven't done the diagnostic to check hdd, I did find another problem with the cdrw drive. I tryed to copy a data cd to the hdd, it can read well and start to copy, then it stoped in the middle and poped up an redunduncy error message. I even tryed to copy the whole cd from dell which is definetely a good cd, and the same thing happened. Since there is no problem with cd itself, it should suggest the cdrw drive is malfuctioning, right?

Hi:

How could you copy data if your Windows has not been installed?

FYI, you may also want to try microsoft.public.windowsxp.general for there are many people might help on Windows-specific problems.

Any error messages and which file did it stop?

If you think that it is the CD-drive (I also can't see how you copied files without any OS installed), I'd call Dell, explain them the situation and ask for a replacement drive. This should be no problem since you are still under warranty.
