Means nothing to anyone

My laptop is getting upgraded on Monday and I need to back up my data. Problem is my company's network doesn't allow me to connect via my home network (A'desk, I'm sure could do it!!!) so I need a wee adaptor to transfer 45GB of files to my PC at home...
The photo means nothing as all I'm wanting is a safe place to keep a picture so I know what way round to connect the plugs! Blipfoto, the ideal picture storage medium
