Hi,

So out of the blue my fx-CG20 had a 'File System Error' the other day and has not been working since. I was about to send it into Casio before I managed to get into the 'OS Error: Please Update OS' screen (I have updated fx-9750GII models so I am aware of the process). I downloaded the CG20 Ver 2 update installer from the Casio website and ran it with no luck, however, with the 'Update Failed' dialogue box appearing at each attempt. Does anybody have any suggestions?

Thank you!

Casio writes about your problem on the CG-20 software manual.

 

 

Never use a computer operation to format the calculator drive.

Doing so will cause a “File System ERROR” message to appear on the calculator screen after you terminate the USB connection between the calculator and computer. When this happens, you will not be able to start up the calculator unless you perform an Initialize All operation, which deletes all data currently in calculator memory. For details, see “File System ERROR” (page α-8)

 

Casio's explanation of File System ERROR:

 

The calculator memory file system

is corrupted or the storage memory

format is one that cannot be read by

the calculator.

 

This is what they tell you to to do when you encounter the error:

 

 

After reading the information under

“Important!” below, perform an

Initialize All operation as described in

“Reset” (page 12-4).

Important!

Performing an Initialize All operation

will delete all data in calculator

memory, including language data.

If you need the data in calculator

memory, use the USB cable to

connect the calculator to a computer

and copy all of the data you want to

keep to your computer’s hard disk

before performing the Initialize All

operation. For more information, see

“Performing Data Communication

between the Calculator and a

Personal Computer” (page 13-3).

 

So they tell you to RESET everything by going into System -> F6 -> F2 ...

but if that error shows up can you even get into the MENU?

So the instructions from the Manual are pretty much useless.

 

I suggest you try updating with a different OS file, or just contact casio's technical support.
