SD image tool/software

[Chrisjuh]

HI all,

I was wondering, i have my Arch Linux ARM installation setup to my liking, with all the packages and settings i need (apart from subversion where i have an open topic here). But now i would like to pull a image from that SD card, so i can use the image tool Win32DiskImager to image the SD again when i etiher wreck my setup by playing with it or when i want to use that SD card to try another configuration.

Is there anyone here who know's a good tool (either Linux or Windows) with proper documentation on how to use it, to pull an image from a SD card and being able to load ik back with Win32DiskImager or dd?

Thnx in Advance.

Yup, use dd.

Thank you for your reply,

I already looked into dd, but i can't really figure out how i can make a full disk image (both /boot partition and data partition) and save this as an name.img

Could you give me a small example on how to achieve this?

Your help is much apreciated thanks!

With the media to backup all partitions unmounted
dd if=/dev/sdX of=filename.img bs=1M
sdX is found in dmesg, it could be sdb or mmblkp0 or ?
A 16Gb card/stick will create a 16Gb img

You didn't say what system, is it a raspberry pi? With a 2Gb card, which creates a 2Gb img.

Well, there are 2gb cards and 2Gb cards, I thought mine was the smallest but was wrong. I made the 2nd partition shy from the end, then did dd dah dah whatever count=1870
So off you never resized partition 2 then ......

I have been asked to make a new rootfs, more compatible with this NOOBS thing, same fat32, then extended partition same size as before with logical ext4, sda5, filling that extended partition. Same count= used.
Other techniques are used to make zip smallest size possible.
