I used this one but after some research last night found that this is a fake and maybe, just maybe that's the reason why the transfer speeds are so slow.
The recommended one is this one. But then again the one I am using works fine in the iPod as far as music playing and file browsing operation goes so I plan to keep it.
That's a brilliant response and very helpful - many thanks - I will make the mod.
I have a 16GB CF in there now but a 64GB iPod mini would be just brilliant.
