iirc most dump commands do this as well, although I haven't said anything because I doubt there is one for HFS. When I was working in a dedicated hosting datacenter we'd occasionally get requests to copy drive contents onto larger drives, and we'd always give a generous estimate, and we'd *always* go long. Until this thread I had always assumed it was because the read operations were having to seek all around the original disks, not that writes were being a pain. If you actually do end up debugging it I'd be interested in the results. _______________________________________________ bblisa mailing list [email protected] http://www.bblisa.org/mailman/listinfo/bblisa
