Re: computer boot (some times) in emergency mode.

[Angelo Moreschini]

Hi

I tried with e2fsck -f /dev/sdc1
but I got the message:

WARNING!!!  The filesystem is mounted.   If you continue you ***WILL***
cause ***SEVERE*** filesystem damage.

Of curse I didn't continue...

How I have to do this test ?
Have I to boot the computer using some utility that didn't need the hard
disk ?
