Card Reader Problem

i have just bought a 2GB SD card and my card reader won’t read from it, but it reads from a 1GB card ok, i’ve tested the 2GB card in my brothers PC and it reads OK.

I bought another card reader and it doesn’t work, now windows says theres a problem because there are no drivers installed (win XP SP2) but it’s plug & play and doesn’t need drivers.

any ideas

or it could be a USB problem ?

problem resolved, i tested the new card reader on my brothers pc and it didn’t work either, so i returned it and the replacement works and the 2GB card is now readable.

still unsure how my original card reader wouldn’t read the 2GB card :confused:
