No please use dd_rescue.

In case Bo's disk already has some problems you are right. But this wasn't mentioned in his OP. Furthermore "dd" always will be installed and "dd_rescue" needs to be installed seperately (BTW as package "ddrescue") -- Never give up ! Best regards / Gruß, Reinhard. "Software is like a parachute.

Smells like a missing feature, and a bug.

dd_rescue == dd for broken media. dd is used far more often, dd_rescue only when there's a problem, so it should be in the rescue system, but I don't think there's a great need for having it installed by default in the real system But feel free to propose it -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I've just been lurking so far but I would be happy to recieve some help on the topic of how to clone an entire disk (with partitions and diferent filesystems and all) on a dual boot home systen. No servers or anything.

Unix command "dd" (= device dump) is your friend !

Assuming the disk to clone is connected to primary IDE channel as master (=/dev/hda) and the target disk resides on primary IDE as slave (=/dev/hdb) the command you need to issue looks like this:

dd if=/dev/hda of=/dev/hdb bs=128M

The option "bs" specifies a buffer of 128MB size. Otherwise "dd" would copy blocks of 512 byte each ...

If you need more information:

man dd info dd dd --help

man rsync

rsync can't handle copying a partition table, and it can't handle copying the actual file system. It's not a cloning tool

Oddly enough, that one limitation is why I suggested it. The problem with dd starting at the actual disk beginning, is, as you know, that it will put the partition info on the new disk. If the new disk happens to be bigger, or different enough in geometry, then dd isn't a good choice. I'm not suggesting that rsync is "the way" to do it. I'm suggesting the OP look into it as a method to use in achieving his goals. I have yet to copy info from one disk to another, without major differences on the disks. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I agree with others, that a Ghost like program would be better than dd, but if you're going to use dd to copy a whole disk, use the read error options to continue past the occasional bad sector: dd if=/dev/hda of=/dev/hdb bs=128M conv=noerror,sync And bs=4k is big enough in my experience. (And I do this a lot including timing tests etc..) If you're target is a tape, then you want (need) a big blocksize like above, but be sure to label your disk with the blocksize you used. I've found that a lot of tapes can only be read if you use the same blocksize as you wrote.

As long as we're introducing non-freebies, here's what I use http://www.storix.com/products_overview/desktop_edition.html Follow the embedded links for details. It only does Linux, but you can do such things as add, remove, or re-size partitions, change file systems (e. g., EXT3 to Reiser), split partitions into multiple file systems, load new SCSI or device modules, etc., all while doing the restore. For cloning, you'd just back up on one box and restore on the other. Excellent email support.
