Hi,

According to the user manual for the device, on page 81, it reads:

If any of these errors occur, turn the the unit power OFF and restart it.
If these error message continue to appear, please contact a TASCAM Service Center.
***Device Error*** (the one you're asking about)
FileErr
FX Busy
FX Rx Failed
I
/F Error
Mount Error
SaveParam Fail
SD-Card Error!
SD Not Found
SD Read Busy
SD Write Busy

Looks like your unit may require servicing at an authorized Tascam service center.

Good Luck!!

Does it say ERR NO FILE? If so, then read on. The reason you have this error is because you don't have a folder on your sd card named MUSICDAT. Solution:

1. Insert your sd card into computer
2. Make folder called MUSICDAT.
3. Then, transfer all files inside the folder (make sure your songs are in MIDI format).
4. Safely remove your sd card.
5. You're ready to put it in you Casio Keyboard!

If you still get the error, take time to read you manual. Read the "using the sd card" part. The folder name might be different for your Casio Keyboard (because mine's a CTK-5000).
...and IF you still get the error, perhaps the songs you meant in your question are MP3 songs (like the ones you play on the iPod)? Then, that's a different topic... :)
Well then, good luck!

Please check if it is not an SDHC (larger than 2Gb) card. Some printers can only read SD (2Gb and smaller) while some can also read SDHC (SD High Capacity) cards.
the C4180 can only read 2Gb and smaller (Standard SD)

If there are sd card error, you cannot format your sd card. you may get messages like

"No SD memory card inserted" messages appears when using digital cameras,
"A media card hard been inserted that contains errors. Do you wish to repair the Media Card now?"
You can read the files on SD memory card, but you cannot write new files or you cannot edit files on SD memory card,
"Access denied", when SD card is corrupted or broken,

... ...

... ...

you can fix sd memory card errors first and them format you sd card.

Is the slide switch in the unlocked position? Have you formatted the cards in the camera before trying to use them?
