Arduino Yun not finding SD card

I recently purchased an Arduino Yun. I was able to make it through the network configuration of the Yun but ran into an issue with I inserted an SD card for the first time. My Yun doesn't seem to be reading the card.

I tried using this command:

cd /mnt/sda1

but was given this error message:

cd: can't cd to /mnt/sda1

After running

fdisk -l

it appears as though the sd card isn't even listed as a device. The card is an FAT32 formatted 8gb SDHC card.

I've searched a lot of forums for similar issues but have come up empty handed. Any help would be greatly appreciated.

Have you tried with a different SD card? A smaller one perhaps? Or one of a different brand?
