10. Select the driver you want to install (in this case, option b).
11. Click Next to install the driver.
The latest driver should now be installed correctly.
W-3: Delay in detection of surprised-removed drive while IO is in progress
In some cases during a surprise removal, depending on the type of IO that is running on
the drive, the drive may take some time to disappear from the Windows Device Manag-
er instead of disappearing immediately. Depending on the timing between the driver
execution path and surprise removal event, device entries will be removed within few
seconds or after the timeout period for an outstanding command expires. This is expec-
ted behavior. The delay it takes for the drive to disappear in the Device Manager under
certain conditions can be safely ignored.
W-4: In Windows 8, upgrading the driver requires a restart before the new driver is loa-
ded
In the Windows 8 kernel, after upgrading the driver to later version, Windows may re-
quest a restart of the computer to complete the driver upgrade. Because the upgrade
process involves changes to the Windows registry and other areas, a system restart
helps confirm the updated driver completes successfully without impacting other pro-
cesses in the Windows OS. The Windows kernel, specifically the plug and play driver,
the bus driver, and the storport driver, determine if a reboot is required (it is not re-
quired in some cases, depending on the state of the devices in the system; the Micron
driver does not request the restart). It is recommended to restart the computer if
prompted.
W-5: In Windows 8.1 and Windows Server 2012 (build versions earlier than 9477), un-
installing the driver using the MSI installer/control panel is not successful
In Windows 8 kernel build versions earlier than 9477, uninstalling the driver using the
MSI installer/Windows control panel will not complete until the driver is removed via
the Device Manager. To workaround this issue, update the Windows OS build to a ver-
sion greater than 9477.
W-6: The OS installation on a P420m/P320h drive fails with the error: "Windows can-
not be installed on this partition"
If the OS installation on a P420m/P320h drive fails intermittently with the above error,
perform a secure erase on the drive using RSSDM before installing the OS.
W-7: System may intermittently perform poorly or stop responding with the latest Mi-
cron driver in Windows Server 2008 R2
When the latest Micron driver is used with the Windows Server 2008 R2 OS, the system
may intermittently perform poorly or stop responding. A supported hotfix is available
from Microsoft to resolve this issue:
http://support.microsoft.com/kb/2468345
To apply this hotfix, the system must be running either Windows Server 2008 R2 or Win-
dows Server 2008 R2 Service Pack 1 (SP1).
Follow these steps to ensure the miniport drivers that use the storport.sys driver can ac-
cess more than 4GB of physical memory:
