Why do you think that? Did badblocks identify any specific problems? A failing hard disk generally shows very obvious symptoms (noises, periodic system lockups due to read retries, I/O errors in the kernel log) before getting to the point of causing the widespread filesystem corruption you seem to be experiencing. Ext4 is generally quite resilient even when handled roughly, so I would tend to suspect a memory issue. That's just a guess, though, since you didn't provide much information. > something Error and Warning on boot time,and after startx mouse can't > move. So how to fix the hard disc now? As Mick said, you don't fix a hard disk, you try to salvage whatever is on it and then you go for a replacement. However, your first priority should be to rule out memory issues: doing any kind of data recovery operation on a machine with defective memory is a recipe for disaster. andrea
