Your computer runs Windows XP, Windows Vista, or Windows Server 2008. You plugged a Secure Digital (SD) memory card into the computer while the write protection on the SD memory card was turned off. Then, you put the computer to sleep or in hibernation. When the computer was asleep or in hibernation, you turned on the write protection on the SD memory card. Finally, you resumed the computer, and then you tried to write to the SD memory card.

When you tried to write to the SD memory card, you experienced one of the following issues:

• The write operation was committed on the SD memory card instead of being prevented by the write protection. Therefore, you may have overwritten the data on the SD memory card unexpectedly.
• You received a warning, and therefore expected that the operation would be canceled. However, the operation seemed to be successful. When you tried to access the newly written data, however, you received an error message that reported that the disk is corrupted.

To fix this problem, you can either download a hotfix or you can do a workaround. To download the hotfix, see the Resolution section. To run the workaround, see the Workaround section.

This problem occurs because some incorrect parameters are written into the registry when the Sdbus.sys driver initializes.
