Can't get Volume Name of memory card using WMI - help

Question

Hello,
I'm developing winform app which is using WMI class (Win32_LogicalDisk) to get information about hard and removable disks. Everything works fine with harddrives and flashdisks, but I just can't get Volume name (for example MySecureDigitalCard) of memory card, it is recognized as removable media but the volume name of it is somehow ungetable.
Thank you for any advice
