I have a problem when trying mounting, checking my ext3 partition. Is a external HD with my "portable" Linux system. Suddenly started to fail, when I try to boot it, the GRUB can't locate the config file, and show me the command line. I boot from my internal HD and try to mount it and have this messages.
