@NIBOU, everything is right and are also interesting information. He does not want to save a LOGO! Program on the SD card, but a LWE project. Edit: That his LOGO! detects that an SD card is plugged, can be recognized by the error message. Diagnostics |

@erwan84, check Wikipedia (search: FAT32) and read the article. Here you get an explanaition what the problem is. For Linux and Mac there are different driver for formating cards. As you made (together with your friend) use windows PC to format the card (Win7: Fat32 Standard). However , if it still don't work, check: + if you plug in and remove the card switch LOGO! to STOP-Mode + Check if the MSD-card holder if it is pressed in is plan with the LOGO! housing. Some user press in the holder stronlgy and this may result in damadged pins on the holder inside. If this happen, then the holder is not plan with the LOGO! housing. + Insert the MSD.card right: If you look to the front of LOGO!, then the pins of the card must be on the top. Hope this helps |

Everything there is to say is already written in this topic. There is nothing new. - Formatting the microSD card on a Windows PC with FAT32. - Disable the "Quick Formatting" option when formatting. - The maximum size may not exceed 32 GB. - No microSDXC with 64 GB or more. - Check whether the microSD card in the card slot of the LOGO! is inserted correctly. The pins must point upwards. |

Hi, If you are not succesfull, best is: 1. Go to a friend and format the MSD-card on his Windows PC (FAT32) 2. If you do not have a Windows PC, then read the Wikipedia article about FAT32. Here you get an impression what can be different. In this article is also listed what driver for Mac and Linux has to be used to exactly get the needed FAT32. What kind of cards work basically depends on the cluster size. A MSD-card up to 32GB formated in Windows 7 in FAT32 has the right cluster size. All is for good working units and for LOGO! 8. According my experiances a fast formating or "slow" formating is no differents, but may be one. I always use fast formating and never had problems if the card, and the card holder in LOGO! 8 is fine. Hope this helps |

I used to have the same problem, a complete (slow) format in FAT32 (in windows 10) solved my problem. |

Some time the TF card not readable by LOGO. I try remove and reinsert again then it working good now. I think the socket inside LOGO card holder may have some oxidation or dust. If you can not read it every TFcards then you could try spray cleaning agent like CRC degreaser to the inside of socket. If not work then you should request warantee claim to LOGO seller. |

I'm so sorry I thought I explaiend my solution here already but I forgot The issue was the logo itself (actualy the little tray where you insert SD-Card) with a new LOGO! from guarantiy (there's no tray part aviable) all worked peprfectly. For information Linux format perfectly usable FAT32 SD-Cards and many other formats. Suddenly all my SD-Cards worked (formated through linux or windows) Thanks for all your helps |

I had the same problem and after many attempts following all suggestions in this thread, I finally removed the tray and found bent pins. This was a brand new logo and I have never forced the tray so that the pins could be bent so much. Check the pins for troubleshooting unknown read errors if formatting does not work. |

Hello Orellanine, at first welcome to the forum.
When I see the slot for opening the card slot on your photo (area marked in red), I wonder what happened there beforehand. You can clearly see strong tool marks. The card slot only blocks if the SD card is jammed due to improper insertion of the card. And this creates the bent pins.

i used in the past a SD card without problems to write Programs on the Logo. I lost this one . So I last bought 3 SD cards (unkown brand) 16 GB and none of them were working! ( even after slow or fast formatting. although The cards worked perfectly for read-write from PC to Card ( even to save/ load the LOGO_U_P from LOGO!softcomfort) when the card was inserted in the logo, i got the message "card unkown" or when i wanted to load the *bin file (that i wrote from the Pc on the card with Logosoft) no program on card the only solution was a brand new sanDisk card 16GB ! So it seems that the Logo can have troubles with some brands of SD cards

I can only say: I have used many SD cards from different manufacturers with different storage sizes (2 to 64 GB) and classes. I never had any problems. With the 64GB, I just had to create a 32GB FAT32 partition. But that was all.
