maybe the latest bios is needed.  would not hurt to install.  if xpsp2 then 
you should not have issues.  but you are.  but check on the drive to make 
sure there are not the 8gig and 32gig limit jumpers set.  I know not 
normally on ide drives but sometimes on ibm's I remember stupid stuff like 


10 second quickie not long enough for you?  Try it for 24 hours.  24 Heures
