Before you give up on the hard drive check the power supply voltages. The HD has yellow (12 VDC) and red (+5 VDC) wires for power. Black is 0V. If voltage is low then the computer does not boot properly and it looks like a HD failure. I just went thru this on my 5300 MK.
If you have an older PC then try hoking up your dead HD and see if it is actually OK. Mine came up fine and my PC indicated only that the motion board was missing.
You also could have a bad battery for CMOS memory.
Jerry at Analam has an excellent sheets with instructions for resetting the CMOS data and also for checking and adjusting power supply voltage. If the power supply is bad and won't adjust then Google the part number off the supply. One company does fixed rate repair for $30.
