Maybe it just doesn't get a drive letter (check Disk Management).
Then, you could check the specification of your laptop's card reader, does it support your card (SD vs. SDHC, size limit)?
Also I recall that Windows 7 update offered an optional update for my card reader long time ago. Now, that I checked, it's about a 32 GB limit, see http://support.microsoft.com/kb/976422
