card reader size restrictions?

[Motley99]

Will a CR card reader read all sizes of cards or are there size limits? I wonder as my computers will not mount a 4 gig card with my reader but they will mount 2 and less.

If there is a limit - why?

Hardware addressing restrictions. Who knew back then what the chips of today would look like internally. Throw it out, a new one is $25.
