Writing SD Card Image

(5) After writing is complete, the software will verify the image. Once verification is done, you can exit the software.

Backing Up OriginMan SD Card Image

The following backup process is performed on a computer running Ubuntu.

Compress Disk Space

To reduce the image size, we first use gparted software to compress the SD card's disk space. Insert the SD card into the running computer and install and launch gparted:

$ sudo apt-get install gparted
$ sudo gparted

In the opened gparted software, select the SD card in the top right corner:

Then right-click to unmount the SD card:

Continue by right-clicking and selecting the "Resize/Move" option to reset the SD card's space size:

Drag the space division bar on the right to compress space. The yellow area is the occupied partition, and white is the free partition. Make sure to leave some white free partition to avoid image boot failure.

After confirmation, click the execute button in the software to start the compression operation.

Once compression is complete, you can close gparted.

View Disk Information

Open terminal and use the fdisk command to check current disk status.

$ sudo fdisk -u -l

In the image, /dev/sdb is the SD card's disk number. Continue using the following command to view SD card partition information:

$ sudo fdisk -u -l /dev/sdb

Start Disk Backup

Now you can use the dd command to backup the SD card to an img file.

$ sudo dd bs=512 count=[largest end number in fdisk command + 1] if=/dev/sdb of=originman_backup.img

There won't be any prompt in the terminal, but the backup has started. It takes a while, please be patient.

After backup is complete, the terminal command will automatically exit, and you'll get the img backup file in the current path.

The generated img file is quite large. If needed, you can use tools like zip for compression and decompression.

The SD card image backup is now complete.
