Ok - sorry, lack of headings & a long section on floppy disks :lol: (here led to me missing "Cloning an entire hard disk".

Just a matter of finding a spare SD card reader then... :)

Quite possibly :)
So this command dd bs=1M if=/dev/mmcblkWhatever of=/dev/sdWhatever will produce a bootable image of one drive (which happens to be an SD card)?

Re: How to backup operating system?

Thanks Joe - that seems very straightforward. I was a bit confused by dding if=/dev/something, but I see that's just a way of copying a partition . But isn't the output a file - so it can be mounted with mount -o loop , but we can't boot from it? If that's right, we still don't have a bootable OS in...

Re: The most expensive R-Pi of the world!

Similar issues (in some other countries) covered here (in particular a way to check if you're be subject to DHL's 'remote area' fees).

Sorry I hadn't noticed this thread. Thanks to Liz et al for interceding with RS - with a bit of luck they'll offer an airmail option soon :)

Buying a laptop for Linux

The community here seems rather active & knowledgeable, so I thought I'd try asking here... My current laptop (a Dell Inspiron 640m) is getting *cough* venerable, & must be getting close to the end of its natural life.

Re: RP in China

RS posts them world-wide from the UK. The shipping fee isn't high (I think $8) but the courier (DHL) might charge extra if your in a 'remote place' or if Chinese customs charges taxes or duties. And you'll have to register interest again... Or you could use google translate on your Farnell emails. ;)

Cheap (?) X-Beetle remote control bug robot

$23 here - so might be available cheaper in similar stores. Looks like it's controlled by modulating audio into an IR signal; I guess a Pi could control it the same way (with the transmitter plugged in to the headphone jack) or directly via IR on the GPIO. Perhaps it could act as a (slightly scarier...

Re: arch = terminal only?

There's a bit of a balance there, since the Arch Linux ARM project is a formal split from Arch Linux. It maintains its own site and repositories. Much of it overlaps, but I am not sure what the implications are by mixing the two projects in a single wiki. I see what you mean. I guess an "Arch on RP...

Can you mount the second partition? Then it should show up as a folder in /mnt or /media & you should be able to cp (or scp) files into it, I think.
