Indeed. That prints the superblock backups. Nice option. I was able to dd if=/dev/ad2s1e without any errors (funny that the fsck says it cannot read lotsa blocks). I moved that (10GB) dump to another machine where I might mount it on a virtual device and perform further recovery measures. Any ideas how to proceed? -- Chris Christoph P. U.
