Coping CF card, with a difference...


I have an embedded device running a flavour of Linux off a 512MB Flash card, which is connected to the ide port via an adapter.

I need to take a clone of the CF card and have found a post with details on how to use the DD command. My problem is how to attach another CF card to copy it to.

I can plug a card reader into one of the USB ports and stick the second CF card in there, but I am going to need some kind persons help to work out the commands I use to DD from one to the other.

you can copy from CF to CF

dd if=/dev/cf_device_name of=/dev/new_cf_device_name
or CF to file

dd if=/dev/cf_device_name of=cf_backup.img
Check in dmesg what your devices are.
