I cannot setup my SD card with the necessary the necessary op system. I have tried using all the techniques described in http://elinux.org/RPi_Easy_SD_Card_Setup.
SD card: Transcend SDHC Class 6 4GB
Computer OS: Vista
In using Win32DiskImager and fedora-arm.. the main problem seems to be that nothing appears when I click the Device button (I run both as 'administrator').
Using flashnul the process appears to complete but the SD card won't open in Windows Explorer when I try to check the contents - on checking the properties the card is full.
I've used SDformatter to reformat the card and tested the card in the Pi with no response. The card works fine if I copy files to it.
None of the suggestions that I've found on the wiki appear to work.
Really appreciate any advice
