badblocks vil fortælle hvilke sektorer i sdb2 der ikke kan læses.
så må du analysere om den/de defekte sektorer måske lige ligger
på nogle vigtige filer.

Eventuelle tabte ting plejer at havne i lost+found på filsystemet
i partitionen, så check der om der er noget der smuttede.


Vil du checke om alle filer er ok er det ikke nemt, undtagen du har lavet
en CRC af alle filer før.

Der findes dog programmer til (delvis) at checke visse filtyper.

f.eks. brugte jeg engang mplayer/mencoder til at checke video filer
(kan ikke lige huske syntax til dette, jeg fandt det med google)

jpeginfo kan til en vis grad bruges til at checke jpeg filer
 osv....
