The following simple code tells if a device has a memory card or not.

TBool CMyContainer::HasMMC()
{
	TBool iHasMMC;
	iHasMMC=EFalse;
 
	RFs fileSession;
	fileSession.Connect();
 
	TDriveInfo i;
	if (fileSession.Drive(i, EDriveE)==KErrNone) {
		if (i.iType!=EMediaNotPresent &&
			i.iType!=EMediaUnknown &&
			i.iType!=EMediaCdRom &&
			i.iType!=EMediaRom) {
			// memory card
			iHasMMC=ETrue;
		}
	}
	fileSession.Close();
	return iHasMMC;
}

Thanks to Mika Raento for this code.
