|A quicker way to determine if there is a problem might be to take the cable that is plugged into your hard drive and plug in one DVD or CD rom drive at a time and see if they are recognized in the BIOS as the computer boots. |
Because you already know that that cable is good (since it boots to the operating system now) it will tell you if the hardware has a problem or possibly the IDE cable.
Also be sure that your BIOS is set to 'AUTO' detect this hardware.
Depending on the age of the computer, it's possible that the cable for your CD/DVD drives has gone bad, or even the extra controller on the mother board. When you have a power surge that causes a problem with a computer its always a painful adventure discovering what all was truly affected.
It's not impossible for those cables to go bad, but my guess would be that your controller port on the mother bad has bit the dust.
