Symptom



When you try to start a Windows Vista or Windows Server 2008-based computer after installing a Windows Service Pack and subsequently uninstalling NetGear Storage Central or Zetera Z-SAN software, you receive the following stop error message:

STOP: 0x0000007B ( parameter1 , parameter2 , parameter3 , parameter4 )
INACCESSIBLE_BOOT_DEVICE

Cause



This problem may occur under the following conditions: You have the NetGear Storage Central software, including the Zetera Z-SAN drivers, installed on a computer running Windows Vista or Windows Server 2008.You perform either an in-place-upgrade of your existing Windows Vista or Windows Server 2008 operating system, or install a Windows Vista or Windows Server 2008 Service Pack.You uninstall the NetGear Storage Central software or the Zetera Z-SAN drivers.You restart Windows.

Under these conditions, the registry entries to load the Zetera ZetSFD.sys filter driver may be migrated from the Disk Class registry subkey to the registry subkeys for specific Disk Class devices by the Windows Vista or Windows Server 2008 setup program.  When the Zetera software is subsequently uninstalled, the driver files themselves are deleted, but the registry entries to load the Zetera ZetSFD.sys filter driver are not removed from the registry by the Zetera setup/uninstall program.  As a result, when Windows restarts, the system attempts to load these filter drivers that are no longer present on the system.  If this failure to load required drivers occurs for the disk device on which Windows is installed, Windows will be unable to access the disk, and thus unable to continue starting.

Resolution



To allow the NetGear Storage Central or Zetera Z-SAN software to be safely uninstalled after installing a Windows Service Pack or performing an in-place upgrade installation of Windows Vista or Windows Server 2008, perform the following actions:
  1. Before installing any Windows Service Pack or performing an in-place upgrade installation of Windows Vista or Windows Server 2008, uninstall the NetGear Storage Central and/or Zetera Z-SAN software.
  2. Install the desired Windows Service Pack or perform the desired in-place upgrade installation of Windows Vista or Windows Server 2008.
  3. Once the Windows or Service Pack installation is complete, reinstall the NetGear Storage Central and/or Zetera Z-SAN software.


If you have already installed a Windows Service Pack or performed an in-place upgrade installation of Windows Vista or Windows Server 2008, you may safely uninstall the NetGear Storage Central and/or Zetera Z-SAN software by performing the following actions:
