Today I bought a Sandisk card reader (Image Mate 12-in-1)just hoping to have my SD cards read FASTER than the built-in card reader of my HP printer's card reader. I placed my Sandisk Extreme III SD card in the slot of the new Sandisk card reader. It asked the SD card needs to be formatted. I tried formatting it and it said that the Windows could not format the SD card.It also erased the existing data. I inserted another SD card (Kingston) and the card reader again asked the card to be formatted. My SD cards work in my printer's card reader without the need to be formatted.
Why does the Sandisk card reader need the cards to be formatted and than it says "Windows cannot format the card" ?
BTW my camera is Panasonic LX2.
