Copy any data and other information you can't afford to loose ASAP. This isn't your exact system but, it has the same error message. Scroll almost all the way down the list.
My system is a Dell Optiplex GX200, 733mhz 20gig,128mb and running XP-Home Edition. During boot-up i usually get this error message ''Dell Disk monitoring system has detected that drive ''O'' on the EIDE controller is operating outside of normal spec. Back up data and replace HD'' Now!..... (1)what is going on? (2)Is this HD failing? (3)If i copy this HD to new HD will the problem follow?
After this warning appears and you press F1 to continue, the system runs fine.
