Hi, My dad has a Sanyo HD camcorder that records on to SD cards. He has two SD cards - the 512mb that came with the camera and also an 8GB which he purchased independantly. Both cards work fine through the camcorder and when the camera is hooked up to the plasma they both work/play back fine fine. However; we seem to be having issues with the 8GB card when it's plugged in to the card reader on a PC though for editing the footage - the card is not recognised by the PC, but strangely the 512mb one is. I use an Epson R300 for the purpose of reading cards and all cards that we both have in existance be it SD, compact flash or memory stick work through it, it's just the above 8GB that does not - the pc does not recognise it. Running XP SP2 with no issues doing anything else on the machine. Does anyone have any idea how I can get this card working without losing the data on it? Thanks in advance. David.
