How can I create a single ISO or IMG file from an SD card?

I have an SD card that contains 2 volumes (H and I). I have found programs where I can turn Drive H and I into an ISO or IMG seperately. But I want a program that will take the entire card and turn it into an IMG or ISO file with all the volume info. I have done this with hard drives using the program reflect, but reflect doesn't see the SD card. IMGBURN will allow me to do either H or I independantly...

Does anyone know what my options are? I've Tried easeus disk copy, easeus backup, winimage, win32diskimager, RMPprep, and USB image tool...

To create image of the whole card (not just one Windows-visible partition), you can use dd for Windows ().

Run CMD as Administrator:

dd --list

Check which device is your SD card. In my case it was: \\?\Device\Harddisk1\Partition0. Partition0 refers to the whole disk, Partition1 to the first partition, etc.

Copy whole SD card to an image file:

dd if=\\?\Device\Harddisk1\Partition0 of=my.img bs=1M --progress

Since you are in windows you can simply use the same program you mentioned 'win32diskimager'. Press the folder icon and select the location and file name you want to create. (sdcard.img) and write. Tool will clone the entire SD card as it is. If you can use Linux you can easily do that using dd command like this

dd if=/dev/sdc/ of=/home/sdcard.img 

Replace the sdc and sdcard.img with appropriate names

If you worrying finding machine with Linux you can simply enable Windows subsystems for Linux (WSL) which gives you full featured Linux terminal on your windows

You can use ImageUSB... this software clones in a single .bin image all the content of your sd card, even if you have multiple partitions.
