Olha como este SO é maravilhoso, além da sua robustez, é privilegiado com uma comunidade que compartilha conhecimento, um caso como este que se fosse em qualquer outro Ruindows, Mac, era formatação certa. Depois de pesquisar em outros sites(nacionais e internacionais) encontrei a solução:

# fsck /dev/sda1
fsck 1.40.2 (12-Jul-2007)
e2fsck 1.40.2 (12-Jul-2007)
Couldn't find ext2 superblock, trying backup blocks...
/dev/sda1 was not cleanly unmounted, check forced.
