Hello,
I've just encountered a really weird problem with the CF card in my HX4700! Its a 4 gig high speed 100 card made by PQI
I lent the card to a friend of mine overnight and when I wanted to use it in my PDA, ALL my files had been deleted. I checked to see how much space was left in it and it was exactly the same as when I had given it to my friend! (1.6 gig free)
I thought the files had just been corrupted somehow. I called up my friend and interrogated him about whether he had been ill-treating my card but he seems pretty clean. All he did was put it into his dad's laptop and copy some files over.
I then put the card into my PC and the filesystem had changed from FAT to RAW. Apparently this means everything has been corrupted (from a bit of research...)
I didn't know how to format the card on my computer so I simply put it into my old digital camera and formated it through there (Canon Powershot A30 Powershot). Now for some strange reason my 4gig card thinks that it's a 2gig card!
I suspect that its because my camera is rather old and 4 gig cards werent recognisable to it!
Now my card is permantly a 2gig card and I am quite displeased...
What should I do?
