The following undocumented behavior of dd is (IMO) a design f= law.

If dd is used to co= py one partition to another, as in

#dd if=3D/dev/sda3 of=3D/dev/sdb3 ...
<= br style=3D"" class=3D"">and if in fact sdb3 does not exist, then dd will o= verwrite the first part of
an existing partition *= sda1*.

It doesn't make = sense that if the "of=3D" device doesn't exist, then another
pre-existing device, not mentioned in the command line, is overw= ritten.
Several websites have incorrect informatio= n about the behavior of dd in this
situation. 

At the very least, this should be documented--maybe I'm missing = something, but didn't see it in the man pages or the texinfo manual.

Thanks,

It doesn't make sense to me, either. But I doubt whether this is a 'dd' bug. It doesn't know anything about devices: it just opens /dev/sda3 for reading and /dev/sdb3 for writing, and it doesn't do anything smarter than that. So if this trashes some other partition then it's most likely some problem with your partitioning.

What version of dd are you seeing this with? What operating system version are you seeing this with? I'm struggling to see how dd could ever do this itself. Perhaps you have a dynamic devfs on /dev or something and when you create /dev/sdb3 it creates a device node for /dev/sda or something? That's a major gotcha and I would suggest passing the conv=nocreat option to dd to avoid that behavior (yes it would have been better called 'nocreate' but not worth changing now after 10 years). cheers, Pádraig.

If this is happening then it is a problem with your operating system filesystem and not the dd command. Since dd is simply copying from one file to another file. If the destination file is somehow connected to a different partition then that would be an issue for the filesystem and not a utility using the file system. > It doesn't make sense that if the "of=" device doesn't exist, then > another pre-existing device, not mentioned in the command line, is > overwritten.

What you are missing is that dd in the above is acting just like 'cp /dev/sda3 /dev/sdb3' or 'cat /dev/sda3 > /dev/sdb3' or other simple copy commands. Since dd is simply copying a file it doesn't know anything about your partitioning. If /dev/sdb3 does not exist then when dd runs it will create a file /dev/sdb3 in /dev. That is simply a file from the perspective of dd or any other utility. What handles /dev depends upon your system. You didn't say what system you were using. What system are you using? How is it handling /dev? What is in your partition table? There are many different ways to browse the partition table. I am not the most proficient with parted but parted is likely the most capable in the face of newer GPT formats. I am perhaps not even likely to be able to interpret the answer but I think this information would be needed and if not me then perhaps another may be able to interpret it. parted /dev/sdb unit s print Bob From debbugs-submit-bounces@debbugs.gnu.org Tue Oct 23 19:03:53 2018 Received: (at 19065) by debbugs.gnu.org; 23 Oct 2018 23:03:53 +0000 Received: from localhost ([127.0.0.1]:38892 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1gF5iL-0007qG-2S for submit@debbugs.gnu.org; Tue, 23 Oct 2018 19:03:53 -0400 Received: from mail-io1-f41.google.com ([209.85.166.41]:33487) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1gF5iI-0007px-QS; Tue, 23 Oct 2018 19:03:51 -0400 Received: by mail-io1-f41.google.com with SMTP id l25-v6so1979466ioj.0; Tue, 23 Oct 2018 16:03:50 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025; h=subject:to:references:from:message-id:date:user-agent:mime-version :in-reply-to:content-language:content-transfer-encoding; bh=s9mo6jxdOplIhX8ccOm+lwnrzE0kAMqjC/EWVlhplmA=; b=Uam4VGjLZC3DMzwlNKeItDw+4t+1ReQ7cEc37Q67s6xHQ9AmAXzLm/G1UiWt4tbO+N RpsGLxUgFBnm0kLx4wF+cpC3Qjojsz5khlSKTXfTq6Gt0RGPMjvK2OukfIC8WNtodV7Z DkOyMEiAXsJP9KOW+CKdL6E2r5nv2esSYy/eehNcg7PaDjQjWObHtGL/5HXHILnmV+fJ 4Pq7s//7jKLZYFv42Gda/lJkLJwTn9CdoXS0Lnn0Zix1oXomWLx9jqYIa9PXueTpqv5k 4RKKtWX2y+lSXrXm8f4gAzxmOUSWGhJtTot/tzT0LppIdJ7H7pLp6NCh37onHaNMyMui 1Lww== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:subject:to:references:from:message-id:date :user-agent:mime-version:in-reply-to:content-language :content-transfer-encoding; bh=s9mo6jxdOplIhX8ccOm+lwnrzE0kAMqjC/EWVlhplmA=; b=ak1VG+373YoC1gyLr+qr2Ovu3gqwa4eKD9xdiXgKBH7h3yfsS2z2lgyxlyoc/6QGcQ zuwGBL4gW5IrPoUbsMCC9AjIiyY9SmJAXdRY/e70IQU5TTwoM+R0jcQUsRwkr/8CZdho s7EWhfoiJjmEAgIo8YKlbrD7CCKnE4+RQygIurj1JCaRveS45qFncapkAL+VQwRmogCK ZNq8Xn/vNY64vp4g9y4j8qlc6tC62Ugl1yaXBMOev7U776goDZCIt1/tPtS0S7bErzQN iHvuAwXvCl+qps4Id7lLhPjTxB8XL2V3d0LG73vTRevxsS0kAurzPjQzERpEHNm5g2xV lhRQ== X-Gm-Message-State: AGRZ1gIh0LXc/0vxOzQJXyLRMqllfU0EG4pGgbR+Jj0rdBF/gGw6keXr LdedFkxLecryGVUBK3vf9UvwJjsP6yc= X-Google-Smtp-Source: AJdET5fgAj5AY4ridc4CDP65Dyo7IOfFrARF1e8UGO98eshYCfxxhonez4PJl5GmMmOBwsCARk0RbQ== X-Received: by 2002:a6b:b78d:: with SMTP id h135-v6mr1502919iof.274.1540335824767; Tue, 23 Oct 2018 16:03:44 -0700 (PDT) Received: from tomato.housegordon.com (moose.housegordon.com.
