I have recently restarted the computer and every time I do and try to boot to XP it says "UNMOUNTABLE_BOOT_VOLUME" on a blue screen. I ran a dell system check and it failed all of the diskchecks except for the spindown test. I used an Ubuntu Live CD and as soon as I got to the desktop it showed a popup saying BACKUP YOUR DATA HARD DRIVE FAILURE IS IMMINENT. The S.M.A.R.T. data also said "read" tests failed and spinup test also failed. I have been trying to copy things through Ubuntu from the OS to an external hard drive and some of the files are not copying. I am also having trouble navigating the corrupted HD. Do you think it's corrupted?
