It seems pretty certain that whatever they sent back from the data recovery house is not a UFS file system. You should try to find out how they got the data there. I can't imagine them creating a new file system. Until you know that, there's not much point trying alternatives, though some of them exist. > Can I somehow regenerate the super block? Regenerating super blocks is simple: that's what newfs(8) does. The trick is keeping your data. Greg -- When replying to this message, please copy the original recipients.
