Microsoft Releases Updates for Windows Vista, Server 2008 and 7 to Support Secure Digital (SD) Cards Larger Than 32 GB

Microsoft has released updates for Windows Vista, Server 2008 and 7 to support Secure Digital (SD) cards that are larger than 32 GB. Consider the following scenario:

• You connect a Secure Digital (SD) card that is larger than 32 GB to a computer that is running Windows Vista, 7 or Windows Server 2008.
• You try to format the SD card, or try to check its properties.

In this scenario, the capacity of the SD card is reported incorrectly.
Actually Windows Vista, Server 2008 and 7 contain a bug which appears when you try to connect a SD card larger than 32 GB. Windows can't calculate the correct size of the SD card.
In Windows, the capacity of SD cards that are equal to or lower than 32 GB is calculated correctly. However, for SD cards that are larger than 32 GB, the high bits are shifted incorrectly by 6 bits instead of 16 bits. Therefore, the capacity is calculated incorrectly.
Windows Vista and Server 2008 users can request for the update using following link:
