How to create a diskimage of an SD card with partitions having different filesystems?

Question

I have a 16GB SD card with 10%FAT32 90%EXT4. I want to get a single disk image file that would contain all of the disc contents. How can I create a disk image of such a disc on Windows 10?

Solution 1

Linux dd.

dd if=/dev/sdX# of=/home/duckqueen/Desktop/usbimage.iso

Solution 2

You could use a tool like ImgBurn, it will read a usb to an iso and also write it back.

You cannot create an ISO image (colloquially: CD/DVD image) from an SD card, for obvious reasons. Perhaps, you should ask about your actual aim.

@DanielB Are you sure about that?

[Daniel B]

@infamoustrey Yes. Though there is no difference in file structure (both are raw images), the term “ISO image” refers to an image of/for an optical disc. SD cards obviously aren’t optical media.

@DanielB Though the nomenclature might be correct, one could build an iso from any file structure could they not? Including that of an SD card?

@infamoustrey: Yes, if you see it like that, it's certainly possible. My impression was that the OP wanted a disk image (which he called ISO image) straight from the SD card. Unfortunately, no clarification was given.

The question asks specifically about Win 10, so you might want to add a sentence about doing this with a Live DVD session on a Win 10 machine (including mounting a persistent drive).

Given that the card has an ext partition, and the asker knows as much, it can be taken that he/she/it has at least a glancing knowledge of Superior OS'. I thought stating all that would be redundant, and if they were going to pursue my answer a 40 second search would put them right. I don't know how or why "persistence" comes into it.

It is unclear from the answer if /dev/sdX# means disk or partition... I mean if you'd wrote /dev/sdX it would be 100% that you meant disk, but why bother with additional #? From the context I think you meant disk...
