Clone expansion card?

[Shrink]

Hi Guys,
If I want to move to a larger expansion card, what do I need to do this?
I have a card reader. Any suggestions for a good fast card? I'm looking to move from a 256 to a 512 or 1 gig. I'm a bit leery of Sandisk. I presently have a Panasonic 256
thanks

I went up from a 512. I thought that was enough but I was wrong. I went with a 1GB Sandisk Ultra II. They are very nice and fast. I have 3 SD cards. 2 are 512MB and one !GB, then I have my 512 MS. They are all Sandisk. I have never had a problems either, they work great. For moving everything, all you need to do is copy everything from one root directory to the other new card. So creata a new folder on your PC and put everything in it, then move every thing from the inside the new folder to the new card. Make sure you have show hidden Items checked. This option can be found in Folder options on the Control panel if you have a PC. That way you dont miss anything.
