Cloning CF/HD on Mac

Dradd · 30 November 2020, 18:20

Hello folks,

Can anyone tell me how it might be possible to clone my Amiga's internal CF HD by using my Mac?
Before anyone asks, the card was set up for me by someone using a PC.

I just want to be able to clone the card so I have a physical backup. I can't use any standard cloning software because macOS won't recognise the format of the card so won't mount it. I understand under Windows there is cloning software that will do this, but I don't run any Windows machines...

I do have FS-UAE on my Mac, but again can't do anything with the card as macOS won't mount it, soo....

Any help welcome.
Many thanks.
Keith

Open the terminal, then use dd to make an image of it. The card is not supposed to be mounted on Windows either, you work on the raw device.

You can see the disks detected by the system with:

Code:

diskutil list

Then you can dump the image with

Code:

sudo dd if=/dev/rdiskNUMBERHERE of=backup.hdf bs=8m

Be careful of course. Don't dump the wrong disk, don't dump in the wrong direction. if = input file, of = output file.

If your card shows up as identifier disk2 when you diskutil list, then your input file is /dev/rdisk2

I keep it simple and use an older version of Applepi-baker, 1.94.

It avoids accidentally using the incorrect disk using the terminal, especially when you're sleep deprived! I found newer 2.x version do more image checking for the linux build so it fails when using unexpected formats such as amiga images.

Thank you so much for this. Works a treat. Brilliant!
