This error is related to the un-synchronization of the system hard drive related issues. Firstly, it is usually caused due to corrupted windows, flawed registry settings or infected virus system. You can perform the self-test by installing The Dell Resource CD.

I think you need to detect your hard drive again because the result of the hard drive self-test returned a “no drive detected” status. This means the BIOS wasn’t able to detect the hard drive. It seems one of the cables got loosed and needs to be checked again. Turn off your CPU and open the CPU case.

Disconnect and reconnect the ribbon cable and power supply cable of the hard drive. Next, start the CPU and go to the BIOS. Try detecting the hard drive again. Once it is detected, repeat the hard drive self-test and see if it works. You should be able to detect it if the drive has no other problem.
