Re: 13000Gig partition badblock check is the same -- do a reiserfsck again ?

[Matthias Barremaecker <info@mh.be>]

Hi Dan,

I'm using Gentoo kernel

Linux hyperspace 2.6.11-gentoo-r6 #6 SMP Tue Apr 19 23:40:58 CEST 2005 
i686 Pentium III (Coppermine) GenuineIntel GNU/Linux

Kind regardes,

Matthias.
