Problem description

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.

Resolution

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

Workaround

This problem occurs because some incorrect parameters are written into the registry when the Sdbus.sys driver initializes. This workaround writes the correct parameters into the registry. To have us run this workaround for you, go to the “Fix it for me” section. If you’d rather run this workaround yourself, go to the “Let me fix it myself” section.

Fix it for me

NoteThis wizard is temporarily in English only. However, the automatic fix also works for other language versions of Windows.

NoteIf you are not on the computer that has the problem, you can save the automatic fix to a flash drive or to a CD so that you can run it on the computer that has the problem.

Now go to the Did this fix the problem? section.

Let me fix it myself

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756  (/Feedback.aspx?kbNumber=322756/ ) How to back up and restore the registry in Windows

To work around this problem, manually you must change a registry setting. To do this, follow these steps:

  1. Start Notepad, and then paste the following text into Notepad:
    Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services sdbus Parameters]SdCmdFlags=hex:06,01,09,19,0a,19,0d,11,10,01,11,01,12,01,18,05,19,05,1a,01,1b,01,1c,01,20,05,21,05,26,05,2a,01,34,02,35,02,37,01,38,01,22,01,23,05,24,01,25,01
  2. Save the file as a .reg file.
  3. Right-click the file that you saved in step 2, and then click Merge.
