Every file in /boot/ is suddenly gone?


Recommended Posts

I haven't rebooted the machine yet. I've captured the syslog (attached). Anyone have any idea about this? Is my USB stick fried? I've only had it about 6 months. If I reboot, will I be able to recover anything off the USB stick? There were some script files I was working on there that I don't have a backup of. What can/should I do next?

 

Here's an extract from the log, at the point where I think all the trouble started.
