I know that, and I said as much in my original message. However, this is not a critical machine and I'm happy to keep it running until the disk actually dies (in my experience this can be months rather than days). Also I would like to improve my understanding of the filesystem and of messages such as this. Can nobody answer my actual questions? To reiterate: 1. Did I get my sector number computation right? 2. Does the base system include any tool for automating this computation? 3. Why is the error message so useless? 4. Are there any tools for exploring a filesystem (e.g. figuring out which blocks belong to a file, or which file owns a block)? How about tools for disk verification? I've found dumpfs(8).
