A new memory card need to be format inorder to work with other device?
My wife brought a new 256MB memory stick due to her existing 128MB is full. She didn't format as her sister took a photo n don't want it to be deleted.
So, this morning, i helped her to transfer her 128MB photos to my HDD and all go smoothly. I was using the protable hard disk to transfer due to the support of memory stick. When I insert the 256MB, it didn't work at all. I put back the 256MB into the camera n the photo still there.
So, is it true that we need to format before use?
