I have a CNC machine. A while back someone I no longer have ability to contact made a back up file of the entire harddrive onto a USB stick. File name is "backup.dd". Now the harddrive on the CNC machine died. I procured an exact same brand and size hard drive but don't know how to go about tranfering the data over. I am not a computer expert but like to learn and would appreciate help to find a 'step by step' instruction from possible formating the new drive all the way to fully functioning new drive.
help neede to transfer backup.dd file from USB stick onto hard drive

The first thing I would do would be to make a backup of your dd file onto another drive.
Then you could use the dd command in Linux to restore the dd file to your drive. Assuming this backup is a complete sector-by-sector image of the entire physical HDD, then you won't need to do any partitioning or formatting.
Alternatively, if you are a Windows user, you might be able to use a disc editor such as DMDE to Copy Sectors from the flash drive to your HDD. I could help you do this.
I would start by using a hex editor (eg HxD freeware) to examine sector 0 of the dd image file.
Launch HxD
Select Extras -> Open Disk Image
select your backup.dd file and Open
Edit -> Select Block
Start Offset = 0
Length = 200
select Hex radio button and OK
Edit -> Copy As -> Editor View
Then paste the contents of the clipboard into your nest post (Ctrl-V or Edit->Paste).

dear fzabkar, thank you. As I said I am pretty inexperienced in such software issues but I do want to learn. I didn't mention in my earlier post that the CNC machine is quite old (1998) . The drive size we are talking about is only 2gig. However the CNC machine motherboard doesn't have have USB connections. I was hoping to 'create the HDD on a newer machine' that has USB connectors and then once done just plug the drive in the CNC. but I could procure a 'parralel to USB connector'if that is needed. my missing understanding is 'how to clone a drive' i.e. fully replace what is currently on it with the 'backup.dd' file. Sorry for my limited understanding and abilities. Can you help?
Could we at least see the information that I asked for?
HxD - Freeware Hex Editor and Disk Editor:

Once we confirm that the dd file is a sector-by-sector image of your physical drive, then we can easily clone it to your replacement HDD via a USB-IDE adapter using cloning software.
FYI, here is the tool that probably generated your backup file:

That said, I would try to replace the old HDD with a CompactFlash card. CF cards are just IDE drives with a different pinout. You can adapt them to your existing setup with a cheap CF-to-IDE adapter. This should be a much more reliable solution, IMHO.

Hi Fzabkar, Sorry for the delay. I am trying to find someone IT trained in my company that can help me provide the information you are asking for and perform the actions that you are recommending. I looked at the links and this is way above my head. Too much terminology that I am not familiar with. It is like entering a new world for me. But I seriously appreciate your help and I will locate a suitable 'middle man' that can understand and perform these tasks and then we can move ahead. please have a bit more patient. The few IT guys we have are usually very tied up with the phone and computer systems and my little CNC machine is 'not their priority' so I need to convince them to help me out. Thank you again for your help. I will be back as soon as possible. Udo
Actually the job is not difficult. All you need to do is to transfer your disc image to a new drive using cloning software. There are probably 100 tools that can do this job. I am just trying to confirm that your DD file is indeed a disc image.
