Problably your card is not dead in any way.
Follow these steps:
- Look in the card if there are some strap to inform there is a booting hd in it (take out the hd and change the jumper);
- Boot from the Workbench disk or the install disk (what version of WB do you have?) and run hdtoolbox to check if the hd is there or not.
- In hdtoolbox, use the "turn reselection on"
If no luck, come back.:horse: And give us some more details.
