Question DD Linux Install from Drive to Another ( 2 Different Sizes)


I just ordered a 60 G SSD drive which I am going to use as my OS drive to replace the drive below.

Can I just use DD to switch ?

dd if=/dev/sda of=/dev/sdb (New Drive)

Thoughts ?

Thanks in advance for your input.

dd is a bit by bit copy and clonezilla/redobackup are file based if they can read the target and write to the filesystem.

dd would work in most cases as long as you have a larger drive. I'd suggest you try it since dd is a tool that may help in the future. Basically G4U uses dd to transfer data. It can be used too. We use g4u all the time on OS's that don't file copy well.

CloneZilla and redobackup are also good choices. They may be faster since they are file based in most cases.
