Windows Driver
W-1: Drive is not appearing online or times out in the Windows Disk Manager with an
I/O error
Confirm the drive and Micron driver have been successfully installed. Check whether
the LED status on the drive is blinking with an alternating flashing pattern. If this flash-
ing pattern occurs, wait until the LED stops blinking (this can take several minutes), re-
boot the system, and try again. Review the Windows System Event or Linux message
logs for drive messages related to this event.
W-2: Unable to upgrade to the latest Micron driver for Windows using the MSI installer
file
When using the MSI installer file in the latest support pack, the Micron driver fails to
upgrade from an older version installed from an earlier support pack.
1. Uninstall the previous driver:
a. Open the Windows Control Panel.
b. Select Programs > Uninstall a program.
c. Select the Micron driver.
d. Click Uninstall and wait for the process to complete.
2. Open the Windows Device Manager.
3. Open the IDE ATA/ATAPI controller tree and right-click the P320h Controller.
4. Select Update Driver Software.
5. Click Browse my computer for driver software.
6. Click Let me pick from a list of device drivers on my computer.
7. Click Have Disk.
8. Click Browse and go to the support pack directory containing the appropriate
driver files. For example: Support Pack Root Directory\Windows Driver\Serv-
er2008R2 or \Windows Driver\Server2012
9. Click OK.
a. If the driver has been signed by Microsoft, the driver icon will have a green
checkmark next to it and the description will state This driver is digitally sign-
ed.
b. If the driver has not been signed by Microsoft, the driver icon will not have a
green checkmark next to it and the description will state This driver has an
Authenticode(tm) signature.
During this upgrade, the Micron driver will appear without a checkmark (appear-
ing as it has not been signed by Microsoft).
