Another option is to format the card and create a single file taking up the entire card. So long as you avoid the first bit of the card where the FAT table is, you can do whatever you like with the rest. You will be able to read the card in any PC. How big the FAT table is depends on how it's formatted, of course. The bigger the cluster size, the smaller the FAT, so pick huge clusters (normally a bad idea). All you need to do then is find the start of your file (which will be noted in the FAT table anyway). Seems to be a popular topic these days. I even noticed my local parts place - www.jaycar.com.au selling SD sockets, which surprised me a bit. Popular indeed.
