[Fife Linux Users Group] Unusable USB device

[Chase]

Hay guys, I got a problem trying to use a SDCard, its mounted on the laptop 
using a USB card reader, and has worked before! now i can do a 
thing :-( Bellow is the fdsik command i ran and bellow _that_ is all the 
kernel errors that appeard in the syslog. I think im having problems with the 
partition table (which is why i ran fdisk) but i dont know enought about 
fdisk to do anything about it.
