Hello all - I am a newbee to the Yun and I am having difficulties expanding the storage memory. I have followed the tutorial, but keep getting various errors. When I load the YunDiskSpaceExpander.ino and walk through the prompts, sometimes I get the message "The micro SD card is not available." Other times I make it through creation of partitions and loading software to the SD card, but then at reboot with YUN RST button, I get error about unable to mount /dev/sda2.
Currently I am stuck at the "...micro SD card is not available" error.
I am using a 2GB SanDisk MicroSD Card and have tried two different cards.
Any ideas?
I got beyond the "... SD card not available" message and this is what I get when I reboot with YUN RST:

Any ideas here?
