Can I move SD card's content to a USB hard drive via 'dd'?

[allfox]

Greetings.

I've just ordered an USB hard drive to replace the SD card as Pi's storage. And now I'm thinking about how to set it up.

I have another smaller SD card with a modified cmdline.txt to direct the boot via sda device. I used it to boot via an USB flash drive. I'm planning using it to boot up Pi via the USB hard drive.

Can I just 'dd' everything from the current running SD card to the hard drive, and after booting up the Pi, I use raspi-config to expand the file system?

I don't want to set everything up from scratch.

You don't have to start with a fresh Raspbian install (as decribed in this tutorial), but can use your existing installation instead.

Thanks, this topic is great.

It told me that I could use rsync to copy the content instead of dd, as it won't copy blank space, so would be faster.

I'll try it when my hard drive arrives.

The file transfer from SD card to hard drive can be done on a computer if this is what you mean.

The Raspberry Pi is a computer.

It cannot be done on a Windows machine.
