Will You Choose Disk Cloning Software or dd Command to Clone Linux Hard Drive?
"I have some normal x86_64 desktop Linux installed on a single 500GB HDD. Now I want to migrate this installation and everything on the HDD to a 500GB SSD actually? Do you have any suggestions?"
Linux operating system has never taken off, and there are still millions of Linux users thus far. However, compared with Windows users, applications for Linux are de-facto much less. For example, when a Linux user wants to do Linux clone hard drive to SSD, it's hard to find the compatible or exclusive Linux disk cloning software. In most times, experienced Linux users will suggest you clone Linux HDD to SSD or clone Linux hard drive to a smaller/larger Solid State Drive by using 'dd' command.
What's 'dd' command in Linux? In simple words, 'dd' is a command-line utility for Unix and Unix-like operating systems whose primary purpose is to convert and copy files. On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files. As long as you grasp each essential dd command concept and have a clear mind for the whole process, you can spend twenty steps more or less with Linux OS and programs migration from one drive to the other.
Here is an example of using dd command to clone a Linux hard drive:
# init 0
# dd if=/dev/rdsk/c0t0d0s2 of=/dev/rdsk/c0t2d0s2 bs=128k
# fsck /dev/rdsk/c0t2d0s2
# mount /dev/dsk/c0t2d0s2 /mnt
# cd /mnt/etc
# vi vfstab
(Modify entries for the new disk)
# cd /
# umount /mnt
# init 0
# boot disk2 -s
# boot disk2
As you see, those commands for computer professionals may seem to be nothing. But for average users like us, can you understand what each line is for? Don't bother. 'dd' command is not the particular Linux disk cloning method.

By removing junk files and useless large files beforehand, you can keep the cloned drive clean. Next, you should use the proper connection way to connect both of your drives to a Windows computer. The desktop computer allows you to connect two hard drives by installing in the tower case or through a SATA-to-USB cable, while the laptop will only let you use the cable or external hard drive enclosure for connection. By the way, if your SSD is newly bought and not initialized at the moment, before heading to the disk cloning process, try to initialize the SSD so that your computer can recognize it with no problem.
