I'm trying to make a backup of my 1TB SSD (80%) to a 1TB HDD, which is empty.

To do so, I'm trying to move 200GB from one to another, so I can format / recover (I don’t know yet), installing Ubuntu Linux instead of Windows 10, but keeping my ./users/me data in the E: disk with Windows 10.

What would be the proper way to copy paste this data? Why not a control+C control+V?

    I’ll just return this question: Why do you think you need a “proper way”? Maybe you want to verify the transfer? Or you want to be able to resume it if interrupted? Maybe performance is important, and/or you heard Explorer is slow in copying data? – Daniel B Dec 10 '23 at 11:39

    it is not clear from your question if you want to have a full backup (including the OS) of your disk on the new ssd. Copy - paste will work for your personal files, but it won't work for the OS: you'll need to make a disk cloning for that, using something like clonezilla – 1NN Dec 10 '23 at 11:41

    Normal Cppy - paste from one ssd to the other of 200GB, on a SATA SSD should take about 7 - 20 Minutes (calculating 200 - 500 MB / sec of transfer speed) – 1NN Dec 10 '23 at 11:48

    Copying large volumes of files will always be faster via robocopy, not through the GUI, and copying files is a very inefficient way of creating a backup. Backups in Windows are done via capturing WIMs – JW0914 Dec 10 '23 at 12:21

Have you considered robocopy in command prompt, which is good for backup handling large amount of data.

robocopy source destination /E /ZB /COPYALL /R:5 /W:5

  • FYI: /zb requires an admin terminal, else it will fail. While this answer will do what the OP is technically asking, copying files is a very inefficient way of creating a backup; backups in Windows are done via capturing WIMs – JW0914 Dec 10 '23 at 12:24
