image of multiple device partitions

did you try burning it? Did you only get a single partition?

I was trying to read the image off of an sd card used in the raspberry pi. It has multiple partitions, some are linux, some vfat. Windows does not assign a device drive letter to the linux partitions. In a linux terminal, I would use dd and identify the device as (for example) /dev/mmcblk0 , without identifying the partition (like /dev/mmcblk0p4) , to copy an image of the entire device. Then when that image is written back onto another device, it would lay down all of the partition information with it.
Does win32diskimager have this capability? Or a better questionis how do I do this with win32diskimager?

Win32Disk Imager does not understand partitions. It only works with the raw devices. So, yes, it will read/write copies of your multiple partitioned SD cards. This was what it was originally designed for and I have tested this extensively.

To expand on this further, Win32DiskImager will list the first drive letter assigned to the device by Windows, even if the drive letter is for 1 partition. It then looks up the device parent for the drive letter, and works with that.

In Linux, you would see:
/dev/mmcblk0
/dev/mmcblk0p1
/dev/mmcblk0p2
/dev/mmcblk0p5 #extended partition
/dev/mmcblk0p6 #extended partition

Windows would look at /dev/mmcblk0p1 as boot (vfat), and ImageWriter will trace it back to /dev/mmcblk0 as the root device.

Possibly the same problem as bug 1330125 then? My SD card driver/hardware may be at fault here. I do not have another SD card reader to test here.

I believe this was solved. If I'm wrong, reopen.
