This problem started occurring recently. When my sister starts up her computer, she gets this:
"NOTICE: The [primary/secondary/primary serial] IDE [master/slave] hard drive SELF MONITORING SYSTEM has reported that a parameter has exceeded its normal operating range. Dell recommends that you back up your data regularly. A parameter out of range may or may not indicate a potential hard drive problem"
The computer runs fine after that notice.
Plese find this problem
