A:Answer NO, I tried putting my larger sized 32 MB memory card & my new 200 GB micro memory card into this card reader, & yes I made sure I put each memory card into their proper slots, I then tried transferring everything from my 32 MB memory card straight to the 200 GB micro memory card but both my laptop nor my desktop PCs would NOT recognize both memory cards at the same time, & it would only recognize each one only when I only put 1 memory card in & copy & transfer everything from one memory to my desktop & then I had to remove that memory card & then put my 2nd memory card into this reader & copy & transfer everything from my desktop to the 2nd memory card.
