Assume that a Secure Digital (SD) memory card slot is enabled on a Windows Vista-based or Windows Server 2008-based computer. When you try to put the computer into either standby or hibernation, the system stops responding (hangs).

This problem occurs randomly.

This article describes the new features and the fixes that are contained in the Windows Vista Secure Digital (SD) rollup package.

The following new features are enabled in this package:

• Support for SD High Capacity (SDHC) cards that are 8 gigabytes (GB) or larger in Windows Vista.
• Support for dual voltage (1.8-volt and 3.3-volt) Secure Digital/MultiMediaCards (SD/MMC) cards in Windows Vista.
• Support for Secure Digital Input Output (SDIO) cards in Windows Vista.

  SDIO cards use an interface that adds functionality for a range of devices, such as GPS devices, Ethernet adapters, Wi-Fi or Bluetooth adapters, modems, scanners, fingerprint readers, bar-code readers, IrDA adapters, FM radio tuners, TV tuners, digital cameras, hard drives, and so on.

Note: Specific hardware is required to take advantage of these new features. For example, the computer must have a supported SD Controller to use SDHC, SDIO SD, or MMC cards.

Some Secure Digital (SD) cards may not be recognized in Windows Vista. When you open Device Manager, a yellow exclamation mark (!) may be displayed next to the card.

Consider the following scenario:

• On a Windows Vista-based computer, you are using a removable universal serial bus (USB) storage device such as a Secure Digital (SD) card.
• You click the Safely Remove Hardware icon in the notification area, and then you click Safely remove Device_name to remove the device.
• You reinsert the device.

In this scenario, you may receive an error message that resembles the following:

There might be a problem with some files on this device or disc. This can happen if you remove the device or disc before all files have been written to it.

Consider the following scenario:

• On a Windows Vista-based computer, you insert a Secure Digital (SD) card into a card reader that is connected to the computer.
• You use the error-checking tool in Windows Vista to scan the SD card for errors.
• You have the Scan for and attempt recovery of bad sectors option selected in the error-checking tool.

However, when the scan is complete, you receive a message that resembles the following:

Some problems were found and fixed.

You do not experience this problem if you use the SD card to perform another action before you use the error-checking tool to scan for errors.
