Which has what advantage over directly changing the image? And the old disc may be slow, but the relative speed (Speed in relation to total capacity) is much better than modern discs. IOW it only takes minutes to read/write it completly. Some month ago i backed up some old HDDs (biggest was 4GB), it nearly took longer to switch on/off the computer and change the HDDs, than the actual time to copy the HDDs. Even with just 10MB/s it's less than 4 Minutes for 2GB. In comparison it takes over 3 hours to copy a modern 1TB HDD @ 80MB/s. Bis denn -- Real Programmers consider "what you see is what you get" to be just as bad a concept in Text Editors as it is in women. No, the Real Programmer wants a "you asked for it, you got it" text editor -- complicated, cryptic, powerful, unforgiving, dangerous. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
