W-8: After uninstalling the driver using MSI installer, the drive is listed as an "un-
known device" instead of "mass storage controller" under Other Devices in the Device
Manager
When the driver is uninstalled using MSI installer, the P420m/P320h drive is detected as
an unknown device instead of displaying as a mass storage controller. The issue persists
after a reboot.
Uninstall the unknown device in the Device Manager and execute the "scan for hard-
ware changes" option. The P420m/P320h drive should now be listed as a mass storage
controller under Other Devices.
W-9: In a system running Windows 7 with two drives installed, uninstalling the driver
for one drive results in a "not digitally signed" message for the other drive in the Stor-
age Controller section of the Device Manager
This is an expected behavior in Windows 7 kernel and should not be treated as an error.
Linux Driver
L-1: Driver upgrade may be ignored in Linux initial RAM disk (initrd) multi-kernel
configurations
In a multi-kernel configuration Linux boot environment with different initrds installed
in custom locations for each OS version, the Linux driver's RPM installer will install the
Micron driver in the default initrd specified in the system's
/boot
directory. This may be
a different initrd from which the user is actually booting. This may result in a Micron
driver upgrade that may be ignored during a system reboot.
Make sure the default initrd filename and location are configured in the
/boot
directory
prior to upgrading the Linux driver for each specific kernel. Once all initrd files are up-
dated with the new driver, the boot environment can be reconfigured back to your cus-
tom settings.
