General discussion • Tool for making 1:1 copy of non-RPI SD card

Hi,

My astronomy club gave me a non-RPI SD card to make copies.
It is very valuable and under no circumstances should it be damaged or data changed.
Instructions say to not use a PC for copying as the PC would 'do something wrong with the card'.
So I volunteered to use my RPI.
Please don't give instructions that involve terminal, shell or dd cmds.

I need a trustworthy RPI OS GUI tool that I can install with 'apt get install'

Then:

• Insert master SD card into a reader plugged into the USB port,
• make a 1:1 copy of valuable SD card on disk
• then allows me to make 1:1 identical image copies from the disk data onto new SD cards inserted into USB reader.

What's the solution?

Thanks,
Gert
