Some time the TF card not readable by LOGO.

 TF card???

You mean mSD card.

 Yes, they all the same.

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 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

Hello for all.

You miss clear the MBR in a mSD card.
Go to Linux, open GParted.
Choose your card in a up right menu, when card is into screen, then open in a left up main menu  "Device", then take "Create Partition Table", then.. (like msdos).. then say Yes/OK.
After that, you can card format again (or format to Ext2 and again to Fat32 to be sure that all are cleared, etc)..
NB: See/ confirm that all operations are completed, that is important.
