Peter, I think I will submit to you that your disk use at Y! is probably quite atypical for a lot of people :-) I think that a lot of people will have a good chance of making a practically complete backup if they get early warning that they have bad sectors as opposed to only noticing months later when they try to access /usr/ports/foo/bar/blaf Eitherway, I will argue that we need more real-world experience with diskcheckd before we decide anything. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
