Remember the Sinclair QL? ICL rebadged it as an office computer with two phone connections - I had to set them up for some managers in th co I worked at in 1985

Back to the Pi.... got my Edimax USB wifi dongle thingy, got a powered 7 port USB hub, added a LaCie 120GB drive and.......nothing works. It's funny how you just plug something into your PC or Mac and it just get's recognised. I suppose this is what it is supposed to teach kids and I am getting lazy.
I have gone through pages and pages of technobabble that definitely takes me back to the dark ages of 1978 programming in 6502 assembler!
You have gone through the wrong pages of technobabble then. there have been numerous discussions about this.
IIRC it seems both the powered hub and the rPi are providing USB power and the rPi doesn't like it. You need to sever the power wire in the USB cable that connects the rPi to the USB hub (ISTR the orange one) and all should be OK.
Search the rPi forum, for some strange reason their are more people on there that are likely to know the answer to tihs sort of question than on the flyer forum.

Sandy - I wasn't expecting an answer on here. I have been through the excellent Pi forums and the problem isn't with my powered USB hub but rather my lack of Linux knowledge and editing weird config files

The config files are actually your friend and are OK once you get to know what does what.
What exactly are you trying to do and what isn't working? You mentioned a CF card - is that mounting OK if you don't connect the hub and external HDD? - what output do you get if you type df <enter> ??
Sounds like you might benefit from to getting to grips with /etc/fstab file and how to mount filesystems. http://www.tuxfiles.org/linuxhelp/fstab.html contains some info that might help you. Also it might be worth looking into some of the basic linux usb commands such as lsusb - http://linux.about.com/library/cmd/blcmdl8_lsusb.htm I'm not sure what distribution you're using but the man pages are helpful if installed - simply type man then the command ie man lsusb and you will find out how the commands work.
Apologies if this is all granny sucking eggs stuff.
All this Pi stuff is taking me back to my first linux PC in 1996 when Linux was new. It was a 386 SX20 with 2mb RAM, using an ancient linux distribution running amateur radio AX25 and newfangled stuff like httpd. A great way to learn about computing which, whilst I'm not in IT, had a big impact on my career.
