I recall a case when I had a hard disk that had got bad sectors and it wasn't accessible through normal mounting anymore. Then a tool came into the game that - I believe - Poul Henning had recommended or written for this purpose. It copies a disk sector by sector to a file (kind of dd), but ignores errors, it just skips sectors it couldn't read (after a couple of retries). The result was, that one had a - albeit - worm-eaten - image of the disk allowing to access the filesystem and getting to the important files with a little luck these not being amongst the corrupted data. Anyone knowing what this little tool was named? Something like diskcopy, devcopy, I forgot. -- Christoph
