I'm having problems reading a new 4gb SD HC Jessops memory card.
My desktop PC just won't recognise it. The PC is running Windows XP with all the latest patches. It's a socket 754 AMD Athlon 64 2800+, just over 2 years old.

I've tried putting it into the internal multi-card reader and also into an external adaptor, connected to a USB port.

The card is for a new camera and I have never been able to read this card. I can read 1gb SD cards, no problem.

I can read the card if I use the camera software, but I prefer not to. I've formatted the card, but it still doesn't work.

Exactly the same thing happens when I use my laptop.

Is is a problem with the card or are my PCs incompatible?
