Were you using an external USB card reader in either or both systems?


Yeah, have an external card reader that works fine in my XP laptop.
It fails to work with Vista. It's a Lexar card reader, tried
different brands of SD cards too. Also have an internal card reader
that doesn't work.

I can read lower capacity cards just fine on Vista with both readers.
