Step 2 Find the CF card device

Before you start, it goes without saying that you should back up any important information that may be on the Psion. It is also possible (although unlikely) to format your computer's hard disk during this step, but this should not be a worry if you take sufficient care during the formatting stage. Also, if you are using Puppy it shouldn't even mount your hard disk unless you explicitly tell it to.

For Linux wizards- to skip this step, determine the device ID (eg /dev/hde or /dev/sdb) of your CF card, ready to partition in the next step

Open a console, and determine what device the CF card is mounted as. You can do this by typing:
cd /dev
ls -l > ~/devices1

Then plug the CF card adapter into your PC, and type:
ls -l > ~/devices2
cd ~
diff devices1 devices2

You will see a line or two beginning with > with no matching line beginning with <. The cryptic few letters are what we are looking for. See image 1
Type
cd /dev
ls xxx
where xxx are the letters you found earlier- these are likely to be hde, sda, sdb or similar. Now plug the CF card into the reader and type
ls xxx*
You should see, in addition to the one you saw earlier (eg "sdb") another entry with a number after it, eg "sdb1". This represents the partition on the CF card, whereas the entry with no numbers (sdb) represents the card itself. See image 2
