My notebook started to behave quite strangely, yesterday I ended without root filesystem, because kernel detected error while reading disk and shut it down. I expect disk to definitely die in next days, so I'm going to buy new one next week, but until that I'm affraid of doing much work on it. XFS survived all those failures good so far, but I allways affraid a bit of data loss. Well everything is backed up, but I hate installing new system, it takes quite long time till I have everything I need. The good side of this is that I will get faster and larger disk and system clean of all historic stuff that I don't use anymore :-).
