Hi all,
I'm new to xbian.

I want to edit the files in my SD card using my computer, whether on Windows 7 or Ubuntu 14.04.

However, when I insert the SD card, the Ubuntu cannot mount the Xbian partition, and gives the following error:

Now what should I do to access the contents of xbian partition on SD card!?

P.S. The reason I want to have access to the contents of my SD card using PC is that my xbian has frozen (black screen on boot) and I don't have backup of my files!!

P.P.S. Can I ssh into a frozen xbian using PuTTY? If yes, what is the default IP address!!!?
