I made this little program for myself to back up USB flash drives and hard disks on Windows. It has support for a few dd options such as bs, count and status=progress.

Feel free to use it if you want. But I must warn you:

THIS IS AN EXPERIMENTAL PROGRAM. IT HAS NOT BEEN WELL TESTED AND IT CAN DAMAGE YOUR DATA. USE AT YOUR OWN RISK.

Usage: wdd if=<in_file> of=<out_file> [bs=N] [count=N] [status=progress]

in_file and out_file can be a file name or physical drive such as \\.\PHYSICALDRIVE0. I haven't tested this with real hard disks, only flash drives.

Example:

wdd if=\\.\physicaldrive3 of=usb.img bs=1M status=progress

To list available hard disks you can use this command:

wdd list

which internally executes:

wmic diskdrive list brief
