Dad sent me an IM sometime late last night, so I don't have full details. We just recently upgraded him to a new Core2 system, Windows Vista, all that new jazz. Has a P965 mobo, 2gig RAM. He moved his card reader over from his P4-WinXP box. Which could read his 4gig SD cards for his camera. Said the same card reader under Vista on the new computer either: 1. Can only read 2 gig of the 4gig cards or 2. Cannot read the 4gig cards at all, can only read his 2gig cards. Are there known problems out there relating to this? It's just a generic 5in1/7in1 something another 3.5" bay card reader that I imagine vista picked up and installed an automatic mass storage driver for.
