Dd 500gb how long

It goes a lot faster when you use a larger blocksize. Using even larger blocksizes are unlikely to result in speed improvements, just higher memory consumption.

If you already have a slow dd running, you can interrupt it and resume with a faster dd instance. For this it is important to know how far the copy progressed already.

For example if it copied more than MiB , you can resume at position MiB using:. If it copied fewer than MiB , your copy will be incomplete. If it copied more than MiB , it will re-copy some already copied parts, which normally does not do any harm. So if in doubt you should pick a value slightly smaller than what you believe was already copied.

You can use the kill command with the appropriate signal to make dd output statistics to standard error. From the GNU dd man page:. Have you tried 'gparted'? You can literally copy-paste a partition from one drive to another and resize it accordingly as needed. You get transfer rate and time remaining. It uses 'e2image' underneath for linux partitions.

There is commercial software called HDClone. It is licensed as both freeware and commercial. Either version can create a bootable pendrive or DVD, as well as copying disks.

Mechanicalsnail - Wait, are you saying I can clone a disc like that? LuisAlvarado, yes, you can clone a disc like that. Mech has used another partition as the output, but you could also output to a regular file named like "sda. Show 2 more comments.

Even if it works I would still fall with the normal dd or pv until I had tried dcfldd with a lot of non-important information. The Overflow Blog.

Ask Ubuntu works best with JavaScript enabled. Accept all cookies Customize settings. After you have the confirmation that your operating system boots-up normally, use the same tool as for shrinking the file system to extend the cloned partition by adding the unallocated space. Using this dd method you can transfer any variant of Windows or Linux OS with all your custom settings, installed programs and files from a larger HDD to a smaller SSD, without the burden to install the OS from scratch and spend tons of hours to customize it.

I did this yesterday on a physical disk connected to my Fedora 26 desktop via a USB toaster type box. The disk was 1TB. Installed on the disk was a sysprep'ed Windows 10 1 partition and Fedora 26 3 partitions all xfs.

I didn't try to shrink anything. Then I ran the xz command on the. Of course a lot depends on how much software you have installed within the OSes on the disk. Your description of the bs switch is misleading. It is not block size, but buffer size and is not related to the block size of the media. I'm pretty sure the variable bs is referencing to block size, not buffer size.

Could I use this method to dd a turnkey linux or other type of linux that is designed to work off of a usb drive, to a hardd drive or ssd? You saved me soooo thank you! I was seeing every sites talking about the complexity of cloning a drive, others tells to use a paid software, others tells to use CloneZilla Again I thank you so much for these great explanations and examples, you've done a very helpfull job!

As others have said, dd has the ability to display progress so you could in theory remove the requirement of piping it through pv. You could do the same manually with the information provided out of dd's progress speed and amount completed but why compute something manually when passing it through pv is of very little cost a couple extra cpu cycles.

My big issue with the article that you should look to fix however is when changing the blocksize using bs and using pipes between "dd if" and "dd of". You should set try to set the block size on either side of the pipe to be the same size or larger on the write side. Ideally you want to use the blocksize most efficient for your destination disk.
