Geeetech

We have a Geeetech i3 pro b printer in our club
When I insert the SD card, the LCD says card inserted. However on the scroll menu it says no SD CARD and if I click this, there are no files shown despite the fact that there are several files on the card. What can we check?

Thank you,
Alex

Press the SD slot and confirm the SD slot can touch the SD card properly. And the printer just can detect the G-code file with an English name.

Hi, everyone. First, sorry for my english, I´m no native speaker.
Second, to the issue:
I own a Geeetech I3 ProB.
I had the same problem: put SD Card, message "Card inserted", but when in the menu, the message: "NO card...".
I formmated a MiniSD Card, with SD adapter, Kingstone 8GB in Windows 10, FAT32, 4KB in allocation size. No change. I tried to name the file auto0.gcode, auto0.g... like I found in other blogs without any luck.
Then I thought that maybe it will be something going on with firmware (arduino on SD reading or so)... But I´m no expert in arduino or marlin programming. So, I give one more chance to formatting, except this time I used a formatting software:
https://www.sdcard.org/downloads/format ... index.html
(for MACs look up for the proper link in https://www.sdcard.org/downloads/formatter_4/)
I performed "Overwrite format" option, or full formatting.
And... It worked!!!
I think Windows makes some funny FAT32 formatting. So go for the source. The software assigns default allocation size for the SD Card, and a clean system volume folder.
Hope this works for others.

Thank you for the information
