is hard drive dead

I have a yamaha cdr hd 1500 when I tried to cop cd to hdd, no go, so I went to hd utilities which showed 0 in all areas, cds play fine. Hard disc is formatted as slave as it should be. Is the problem in a circuit board some where in unit or is it a bad hard drive? Why would'nt it register on hdd utlities? HELP.
