Hi.
My friend wanted to get photos from my SD camera card onto his Acer laptop via the card reader. He runs Windows XP. The card would not register.
The funny thing is that he could get some SD cards to work but some did not work on his laptop.

I was full sure it would resister on my Ubuntu 9.04 Acer laptop at home -> it did.

Does anyone know why this is? Is it due to the actual SD card maker or the card reader? Or perhaps even the OS?

Is there a solution to force the card reader to read the SD card?

Make sure your card formatted in some way that is compatible with window (usually FAT32).
Another way might be to format the card on the XP machine, copy files onto it from your ubuntu machine, then try reading the card again in the XP machine

Thank you rpmorrow.
