When I boot my dell I have a strange message;

 

"Dell's disk monitoring system has detected that Drive 0 on the primary EIDE controller is operating outside of normal specification. It is advaisable to immediatly back up your data and replace your hard disk drive by calling you support desk od Dell Computer

 

Strike the F1 to continue F2 to run the set up utility"

 

if I push F1 it works.

 

I have made a format of c: and i have still the message.

 

What does it mean?
