No need to use 'cat' if 'dd' works for you fine. > To get the "name of device" I will normally run the "fdisk -l" command to > see what device are available.

As Darrick already mentioned, write to the disk (i.e. /dev/sda), but not to an individual partion (i.e /dev/sda1). > I have also found that when running "makeimage.sh" it seems to work more > reliably if any pre-existing partitions are first removed from the CF card > using "fdisk".

What happens in your case when you don't remove the existing partitions first? I am asking because you said 'it seems to work more reliably". > I have a peculiarity on my CentOS machine where it doesn't always > "autodetect" the CF card when I insert it into the USB reader.

This always works but requires > re-booting at each step of the burn. I don't know CentOS very well. I am using the Suse distro. Of course I have noticed there quite a few probs with USB hotplugging as well. Often it's good enough to pull the card, pull the USB card reader, insert the card reader, insert the CF card.
