File system problem
 

Hi,
I recently notice error on the filesystem; after fsck (and after fixing several errors) I notice that some files were gone.
It's possible that errors on the file system make file disappear?
Thankyou

Yes, files whose structure cannot be repaired (they are corrupted) have their inode removed, deleting the file. Using a journaling filesystem, like EXT4 can help prevent this from occurring. Regular filesystem checks, which are the default, will also help prevent errors from accumulating, which can cause this to happen.

Thankyou macemoneta.
So ext3 isn't good enough (it was my case)?

look in lost+found
 

Each partition has a directory called lost+found. When fsck finds file fragments which it is unable to identify it places them in that partitions lost+found directory and gives them a meaningless name. If you have files in lost+found you might be able to identify them from the contents of the file.

Be sure that you are looking in the correct lost+found directory. There is one for every partition.

EXT3 has a journal (EXT4 has improved reliability and performance features). Do you know the cause of the filesystem corruption?

Yes, power loss
