Data logging on memory card SD Comfort panel /TIA

Hello,

Normally I’m working with an USB stick for all historical data.

Now I use for the first time an SD memory card in a Comfort panel (the one that Siemens preconize, 2GB) but it do not work. When I configure the Comfort panel for keeping the historical data on a USB then it is working OK, but when I use the exactly same application with an SD card (and change the storage location to \Storage Card \SD) then there is always an archive error and nothing on the card.On the card in my laptop I have access but it is empty. I do not think that the new card is damaged. The card is plugged in the left slot, used for the memory data.

Does someone have an idea or what doing I wrong? I'm using TIA.

Thanks and best regards
