How to expand a .dd file from a USB source to a USB target in Linux
I have a .dd image of a Wintel Fat 16 NT4 system I need to restore to external media such that I can pull individual files from both partitions of the hard drive that was imaged. The result need not be bootable. It needs to able to be browsed and files copied inside of a Windows kernel when completed.
After wrestling with the issue inside of Windows, it appears it is best to do this from a Linux environment.
I very little functional Linux command line experience, so I am looking for a direct, step by step procedure to complete the following:
From the /root
Source file drive_image.dd on USB stick A
Restore it to USB stick B
Using the dd command.
Please assume butt stupid Linux knowledge because that is the case. Thank you.

Please confirm what is the Linux distribution you are using. If it's a live CD, please give URL of iso so I can run it here

I finally heard from the vendor, and it appears he is having issues at well. As I expected, an NT4 formatted FAT 16 with a DOS partition is the problem.
But thanks for looking at it this far. I have an old 9x utility that should handle this, Snapshot Drive. I just need to find a way to get an output device connected to the actual machine to use it, and being NT4, no device manager.
"It looks like the NTFS partition is either messed up or arcane enough
that Linux refuses to mount it. It might be a job for chkdsk under
Windows, but in any case it looks like it might require a bit of
creativity to extract the files, more than any predictable sequence of
commands. I also tried copying the full image out to a 1GB USB stick
and plugging that into a Win7 box in order to use CHKDSK, but no joy.
The NTFS partition is simply seen as empty by Windows 7. Maybe it is a
really old version of NTFS unrecognized by modern Windows? Conceivably,
and I mean VERY conceivably, perhaps it is actually HPFS which could be
mountable under Linux with the proper modules installed; however I
haven't tried that. HPFS uses the same partition ID as NTFS."
