Backup on USB-unsuccessful- R30iB and R30iA controllers

I'm pretty sure I had the same issue awhile back. Although I was using an 8gb flash card at the time, not a USB. I could not find anyway around it, and just had to find a smaller size card to use instead.

if you have over 255 files it will not complete. I have found that you can only place 255 files on the root directory. in a folder the number of files is pretty much unlimited.

I use an 8GB USB stick without problems. Format using FAT32. If you format in the old FAT you cannot save many files.

Format your flash drive from the File menu of the robot. Thus, these problems should not occur.
