So I'm following the instructions on this page...

http://www.embeddedarm.com/software/arm-linux-fastboot-ts7300.php

I've been using linux for years, but generally as a user. I'm not
familiar with the dd command. I get to the part that says:

"Using an SD Card reader and the "dd" utility, copy the image to the disc device
of the 256MB SD Card:
$ dd if=sdimage.dd of=/dev/sda"

I have the image downloaded, so I run the command...
dd if=<myimage.dd> of=/dev/sda

It doesn't seem to copy. Later I succeed - but first learn that my SD
Card is actually /dev/sdc. You can all see where this
is going :) Yep - sda was my Hard Drive! I didn't find  that out until
the following morning when I turned on the computer
and it didn't boot.

Now I should have known better than simply cut and paste a command
from a web site without understanding it
before using it. However, maybe this page could replace the "sda" and
replace with "<your_sd_device>". and provide
some guidance on how one goes about discovering exactly which device
is your SD Card. Perhaps also a warning
that dd can overwrite your hard drive if the wrong device is specified.
