I also had the same issue, when I bought this PC (my home PC) the windows 7 said that the Disk will fail and all software said the same, it is more then 5 years and still working like new
I have something like this (I just ignored all the errors):
"
Windows has detected a hard disk problem." = This is the main error.
"
Back up your files immediately to prevent information loss, and then contact the computer manufacturer to determine if you need to repair or replace the disk" = This was the text in the error box.
"Hard Disk: S.M.A.R.T. Capable and status bad." = this is when the
computer starts.
