I have a 2GB USB stick formatted to FAT32 which gives a usable size of about 1.8GB, I can normally fit on a 1 hour file on the empty stick, Primeval off ITV will fit fine but I get a message "No more storage available" when I try and transfer Ashes To Ashes off BBC1, therefore I am assuming then that the BBC 1 hour file must be larger then 1.8GB, if this is the case I can buy a 4GB stick which should work, is there a way to check how big files are on the HDR so I know this is the problem?
