I would like to back up an entire SD card into a single file on Windows 7. This SD card contains an two ext3 partition which don't appear as a letter drive on Windows.
I've tried Win32 Disk Imager, which seems to have a read option, but needs a letter (
G:, ...) to select the SD card drive.
Essentially, I'm after the Windows equivalent of this Linux command:
dd if=/dev/path/to/disk/device of=sdcard.img bs=1M
Is there any way to do this directly under Windows?
It would also be better if the resulting image was in a format that could be restore via
dd, if copied onto a Linux machine.
(Although I'd prefer a single file for the who drive, a file per partition would also be fine.)
