Says problem with cf card ,but bought new one still the same

No, usually you'll just get a warning that the card is missing but the camera should power on.

that is the correct way . Maybe you need to activate sdcard option on the new machine it could be off

Try formatting the card in the camera.

So far as I am aware, the 5400 will support only up to 2GB cards. As to the firmware upgrade you mention, I don't recall that that has any bearing on the max. card capacity; but it's worth doing for the RAW format support (for me, at least). Cheers and good shooting. Davo, Tas. 

Nope, this is not card anymore.

As you know CF is card failure, sometimes this cause to start error 99 , that is lens error , even if there is no problem with the lens.

This happens because the built in software in the camera can get messed up after an error CF.

You fix the problem calling Canon, they will guide through upgrading the firmware in your camera.

First ensure that you are using the camera menu and command to format the new card, and that new cards are properly inserted into the machine.

Call Canon support to get a firmware upgrade.

You'll have to create backups of your songs and transfer those backups using USB to your PC. Then with the 8 GB card inserted you can reimport them to the Tascam (USB) and restore them to the current working song which will then get saved on your 8 GB card. Do this for each song and then you can discard (delete) those backed up song files while connected to the PC.

Hope this helps.

You can put max 1GB cf card.

You can always try the reset button. It is under the flap where the USB/Video out/ and power connector is. It is just above the power connector.

To write to the CF card, you need a card writer on your pc. If you still have problem accessing the CF card, it might be corrupted. Try to reformat the CF card with FAT16 file allocating tablet in the format option on the computer. If its not possible to format this, you probably need to get a new CF card.

Have you tried formatting these cards in your camera? You will find the setting in the menu as per page 26 of the manual. Also check that the correct card type is set for xD or CF as appropriate.
