"I am getting an err 02 is my firmware corrupted?

I have a new imac. I used a card reader from lacie. I clicked erase disk. I have not been able to get the camera to read a once used Sandisk ultra II 2.0 GB. So I bought a new Lexar Platinum II 80x 1GB. Still err 02.
I checked the pins on my camera and they are not bent.
I have tried to format the card from the card reader with no luck."
I have tried the disk utility and it didn't work.
I don't have the sync cord. Is it possible that mac tiger has corrupted my firmware? Any other suggestions? HELP. I need to work.

A card reader can ruin firmware in the camera. It's not even connected to it. It's possible, however, that it may have corrupted the card:

Err 02: CF DRIVER

DESCRIPTION: This error occurs when image data cannot be written to the CF card. This error can occur when the CF card is not fully seated in the camera or if the camera does not detect a card-ready signal within a specified time limit or when the CF card is not usable because it has been corrupted or physically damaged. It can also occur when the camera's battery level is insufficient to completely write the file to the CF card.

REMEDIAL MEASURE: Use the DC Coupler or recharge the battery first. If the error continues to occur with sufficient power available to the camera, check that the CF card is properly inserted. If that's not the problem, then try replacing the CF card. If that does not solve the problem, have the camera and one of the CF cards that is causing the problem examined by a qualified service technician. This error is similar to Error 22 on the D30.

Try running a different card recovery utility. There are literally hundreds out there.
