How to Resolve the Error "The Driver Detected That the Device DeviceHarddisk0DR0 Has Its Write Cache Enabled"

How to resolve the error "The driver detected that the device \Device\Harddisk0\DR0 has its write cache enabled"

Problem:

There are a couple of types of errors that come from write cache being enabled. If the error is because the write cache is enabled, you can simply use the Dell OpenManage Software to change the Write Policy on virtual Drive from Write Back to Write Through.

This is documented in several places, including the Microsoft TechNet website. 

Solution:

This same error, in the Windows event log (Event ID 32) may be due to the hard drive firmware on the drive, the RAID controller or the storport driver as well. Use your preferred method to update your Dell server. For example, the Dell Support web site is a good place to start.

1. Navigate to Drivers and Downloads or use the document link to the Dell Support web site.
2. In the Drivers and Download section, enter your Service Tag.
   You will be redirected to a page that has the choice for the Operating System.
3. Choose your Operating System and select the the proper storage section.
   You will be able to find the storport driver in one of the storage sections.
4. All hard drive firmware will be listed by device category, as will the storport driver and controller.
   Category examples are:
   • SAS drive
   • SAS non RAID
   • SAS RAID
   • SCSI non RAID
5. Update the Storport, drive firmware, and drive controller.
6. Also install the Dell OpenManage software to check write through and verify the option to Write Through is selected.

The "write" setting on the RAID controller, use of older drivers and firmware, and an old storport driver are main causes of the event ID 32. Although, there are other reasons why this error may occur, these are two good places to start.
