It's not a matter of working: it's a matter of recovering. A bad disk block could potentially destroy a file or a directory, but shouldn't make a filesystem not mountable nor recoverable. > As for crashed disks I rarely bothered trying to "fix" them anymore.

The problem is that I couldn't save anything: the XFS volume refused to mount and the XFS recovery tools refused to fix anything. It was just a single disk bad block. For example in ext2/3 critical parts are replicated several times over the volume, so there's minimal chance of being unable to mount the volume and recover important files. _______________________________________________ Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
