Some years ago  I bought a USB multi card reader.   Haven't used it until  tonite when I tried to format and write to a 2G SD card ex wifes old camera.  When I tried  I gat that it was write protected.  Put the same card into the SD slot on wifes laptop can read and write to it OK.  Put the USB reader into her laptop and it's write protected.   I suspect from looking online that this unit is read only and I need one with a  write protect  switch.

Can anyone recommend  a reader / writer  to me  that doesn't cost the earth??

Thanx in advance..
