Error 30 I see an error 30 indicator. What does it mean? And How can I fix it?

The "E30" error code is displayed when reading/writing data on a CF card has failed. Especially, the error code "E30" may appears when you tried to remove a CF card while the camera was processing data. Solution To clear the "E30" error, try performing the following procedure. 1. Try using another CF card. If you have another CF card, try loading it in the camera. If the error code is not displayed when the other CF card is loaded, there may be something wrong with the first one rather than with the camera. 2. Use your computer's ScanDisk utility to check the CF card for errors. Use ScanDisk to check the CF card for card error or card failure. Refer to the instruction manual for your operating system or Windows Help for further instructions. (If you are using a Macintosh, use the "Disk First Aid" program to check for card error or card failure. Refer to the instruction manual for your Macintosh OS for further information.) Be sure to back up the data on the CF card on the computer before you check the CF card. If a card error or card failure occurs when you use your computer's ScanDisk, there is something wrong with the CF card. Follow ScanDisk's on-screen instructions to solve the problem. 3. Format the CF card with your camera Try to format the CF card with your camera. Please refer to the "Camera User Guide" for your camera for instructions on formatting CF cards. Also, please note that formatting a CF card will erase all data on the card. Once the CF card is formatted, follow the procedure described in step 2 above and use your computer's ScanDisk on your computer to check the CF card for errors. If a card error or card failure occurs when you are using computer's ScanDisk, there is something wrong with the CF card.
