Zdravim, 

mam nejaky zvlastny problem s diskom. Uz dva dni vzdy ked vypnem vecer po praci notebook a opat ho zapnem,
objavi sa nekonzistentnost dat v ext3 filesystemoch a pri boote musim rucne pustit fsck.

Pouzivam LVM a mam dva oddiely pokazene (root a home). /boot je v poriadku.
Pozeral som stav disku cez smart tools. Inspiroval som sa clankom na http://www.linuxjournal.com/article/6983.
Vsetky udaje v poriadku. Ziadny FAILED test.

Mam disk Western Digital 160GB, model WD1600BEVT-60ZCT0.

Vypis /var/log/messages, ktora mi pride podozriva:

Nejake relevantna diskusia http://www.mail-archive.com/debian-powerpc@lists.debian.org/msg58747.html
kde tvrdia ze ide o chybu HW ale dotazujucemu vysli zle smart testy.

Moze to byt bug kernelu/ext3 alebo je problem v disku?

Vdaka za kazdu radu ;)
