[Sorry for the sensational title] I have had this laptop for three years. It ran Linux (Debian unstable) from the start and its hardware has been very unreliable: I changed hard disks twice and the motherboard thrice. My DVD drive started failing some days ago (this one is 'original', 3 years old). But I don't mind as I am not under warranty anymore... This morning the machine booted with fsck errors on my hard disk. I am not sure if I did the right thing, but I said clear the inodes, and I ended up loosing some programs(*) (du, dircolors, etc..). The day starts well isn't it? Sounds like I will have to switch disks again...
I halted the machine correctly yesterday night. I never dropped the box in 3 years. Am I just being unlucky? Or could the fact that I am using Linux on the box affect the reliability in some ways on that particular hardware (Dell Inspiron 8100)? I run Linux on 3 other computers and never had single problems with them. How can the file system (ext3) be messed up the way it was this morning after I stopped the machine correctly yesterday? Could a hardware failure look like bad sectors to fsck? Attached the output of smartctl -a /dev/hda, whatever that helps. Jerome (*) I accept tips on discovering and maybe recovering which files have been taken out of my system...
