Hi Guys,
I used the C-guys drivers for the sd-link11b with my c760 running cacko 1.23, kernel 2.4.18, rebooted the Z, fdisked the sd card and layed down a vfat filesystem on it. Now I can happily access all 4GB of the SD card on both my Z and my Toshiba Laptop! Thanks guys for all your help. Now on to my wifi problems.
