How to clone the contents of SD card

The raspberry pie has been installed, and the rest needs to be installed repeatedly. It is not possible to copy files directly because new partitions are generated during installation. Using dd as a clone, you can copy it all over.

# # step1. Locate your SDCard

Enter on the command line:

Diskutil list

Displays as follows:

/ dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme * 251.0 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_HFS Macintosh HD 90 . 7 GB disk0s2 3: Apple_HFS d 34.9 GB disk0s3 4: Apple_HFS f 65.6 GB disk0s4 5: Apple_HFS g 59.1 GB disk0s5/dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: Apple_partition_scheme * 14.2 MB disk1 1: Apple_partition_map 32.3 KB disk1s1 2: Apple_HFS Flash Player 14.2 MB disk1s2/dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: Apple_partition_scheme * 16.1 MB disk2 1: Apple_partition_map 32.3 KB disk2s1 2: Apple_HFS Flash Player 16.0 MB disk2s2/dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme * 31.9GB disk3

Then your sdcard is the drive letter disk3.

# # step2. Make a mirror image with the original card

Enter the command line to make an image file:

Sudo dd if=/dev/rdisk3 of=/Users/liangwei/Downloads/yihud3.dmg bs=1m##step3. Format the new card

Take out the meta card, put the new card in, then with step1, find the new drive letter, and then command line:

Diskutil unmountDisk / dev/disk3 sudo newfs_msdos-F 32 / dev/disk3##step4. Burn and write new card sudo dd if=/Users/liangwei/Downloads/yihud3.dmg of=/dev/rdisk3 bs=1m

Raspberry pie mirror cards are also burned in the same way, but when formatted, they need to be formatted as FAT16:

Sudo newfs_msdos-F 16 / dev/disk3 on how to clone SD card content to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
