Hi
Many thanks for replys .
we managed to fix the problem without cloning the SD card.
In fact, we reset the controller to last auto save . then we restore from the backup that we had from this robot.
I got suspected that if really the sd was corrupted and restore to last auto save could solve it.
However, the problem started with an alarm that meant the robot can not read pick master library. N.B. Our robots are programmed using palletizing powerpac.
