The reader in my wife's old laptop (Compaq R3240) would not work with
1gB or 2GB cards, but would work with 512MB and smaller.  It would
detect the card but have random contents displayed and certainly
wouldn't read.  An SD reader in a USB printer on the other hand
connected to the same machine read all the cards fine.  There certainly
are some misdesigned SD readers out there that fail with larger cards
due to having made invalid assumptions.

Sounds like that particular readers is junk and belongs in the trash. :)
