Card Reader not reading SD HC Card

I Have a Dazzle* 6 in 1 card reader which works with most cards without the need for a driver. A friend recently used a SD HC Class 6 card to capture some video with his Sanyo Xacti camera. My card reader won"t recognise the card. Are their any drivers workarounds etc.
Thanks Jay
Go to the SCI Microsystems website and look for drivers. But I doubt you will find any that are for a 7 year old unit. That type of SC card is probably too new.

I'd post the URL but it keeps getting this post rejected.
