Reiser should be better than that, I am surprised. One method would be to look at it forensically. 1. Pretend your main one is the 'suspect' disk. 2. Are you able to mount it from Knoppix or another distro? Use knoppix to boot up and dd an entire copy of the drive (with this size it might take awhile but this is a sound method if you have the time for it to run). 3. dd it to another removable device, preferably another (USB external) hard drive so that you don't run into weird geometry issues or other time consuming things. 4. Now that you have another copy you can truly play around with other stuff. It may be that you can recover more than you think because of the fact that you will be on a ramdrive and _some_ of the files that may otherwise be lost, will <possibly> be in ram. Maybe a bad sector on the disk only happenned to have a few files on that spot. If that were the case, then you would be lucky and only maybe lose a small amount of data. 5. Try fsck and some of the same commands, now with the new drive and see what it does with the same files on the NEW drive. 6. Now that you have two copies, you can run other tools, etc. Maybe on the COPY you can play around with fdisk and get it bootable. The way I would approach it would be to try to get as much as I can, even if it is only half of the data lets say it is a start. HTH -- Marc Wealth is the product of man's capacity to think.
