Can you send us the errors which fsck and/or the kernel reported? What version of the kernel were you using? What version of e2fsck/e2fsprogs were you using? What kind of hardware are we dealing with? You might also want to check /var/log/messages to see if there were any messages from the disk drive indicating hardware errors (i.e., bad blocks on the disk drive). > however, I can see any files and folder in debugfs and can rdump them to > another folder and format ... and reinstall > so bad!!! > > Question: > Can I have a simple way to recover the data without reinstall and format Normally this isn't a problem; you should needed to do so. But your bug report / question is roughly equivalent to complaining to a car company that "my car stopped working, and the only way I could fix it was to take it to a smelter, melt it down into scrap heap, and then reconstitute the car from the resulting metal slag. This is so bad! Can you tell me how to fix it in the future?" And you don't tell the car company any symptoms before you destroyed it, and you don't even allow the company to look at the malfunctioning car (since you've already melted it down into scrap metal) when you complain. Heck, you don't even bother to tell the car company what the model or year of the car --- they should be able to figure that out by mind-reading. For future reference.... the e2fsck page has a section on "reporting bugs". This is also useful steps if you're not sure whether you're dealing with a bug, user error, or hardware error. Something else which is useful if you have a fairly recent version of e2fsprogs, is to use the "e2image -r" command (read the man page for more details), and make provisions to send me the raw metadata image dump so I can investigate what might be going on. We'd like to help, we really would.... but we need information in order to help you. At the very least, please don't destroy the filesystem until you give us a chance to tell you what kind of information would be most helpful in trying to help track down the bug (if bug it be) or cause of your difficulties. - Ted
