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 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.

Consider the following scenario:

• You have a computer that runs Windows XP, Windows Vista, or Windows Server 2008.
• You plug a Secure Digital (SD) memory card into the computer while the write protection on the SD memory card is turned off.
• You put the computer to sleep or in hibernation.
• When the computer is asleep or in hibernation, you turn on the write protection on the SD memory card.
• You resume the computer and try to write to the SD memory card.

In this scenario, you may experience one of the following issues:

• The write operation may be committed on the SD memory card instead of being prevented by the write protection. Therefore, you may overwrite the data on the SD memory card unexpectedly.
• You may receive a warning when you try to write to the SD memory card. Therefore, you expect that the operation will be canceled. However, the operation seems to be successful. When you try to access the newly written data, you receive an error message that reports that the disk is corrupted.

You have a Windows Vista-based computer that has an Secure Digital (SD) memory card inserted. You resume the computer from the system Hibernate mode (the S4 power state). Then, you try to shut down or restart the system. In this scenario, the system may stop responding on the shutdown screen.

When the issue occurs, you must remove the SD memory card to recover the system. Or, you must press the power button to forcibly shut down the computer.

Notes

• Removing the SD card may cause data loss.
• Sometimes, after you resume the computer from the system Hibernate mode, some applications may stop responding.
• This problem does not occur on a Windows Vista Service Pack 1 (SP1)-based computer.

Secure Digital: A flash (non-volatile) memory card format developed by Matsushita, SanDisk and Toshiba for use in portable devices, including digital cameras, handheld computers, PDAs and GPS units.

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.

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

Consider the following scenario:

• You develop an application that sends an IOCTL_SFFDISK_DEVICE_COMMAND request to a Secure Digital (SD) card.
• You compile the application on a 32-bit version of Windows Vista.

In this scenario, the application obtains a “Success” value from the SD card. However, when a 64-bit version of Windows Vista uses the Microsoft Windows-32-on-Windows-64 (WOW64) subsystem to run the 32-bit application, the application obtains the following error message from the SD card:

ERROR_ACCESS_DENIED

When you use a 16-bit PCMCIA card, such as a Compact Flash card, a Smart Card, or a Secure Digital (SD) card, the following error message is logged in the System log after you resume a portable Windows Vista-based computer from hibernation:

Event ID: 9
Source: pcmcia
Level: Error
Message: The PCMCIA controller encountered an error powering up the inserted device

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.
