detected that the device \Device\Harddisk0\DR0 has its write cache enabled

We have a AD server on a Hyper VM Windows 2008R2, recently I received the following warning. What to do with it? If I disable the cache, what's the impact? thanks

"The driver detected that the device  \Device\Harddisk0\DR0 has its write cache enabled. Data corruption may occur."

In diskmgmt.msc or device manager go to the device properties / policies and if you want you can disable write caching. This is only a warning that if you lose power or have equipment failure it might result in data loss or corruption. Turning off write-caching will impact performance .. Write Caching is on by default but Turn Off Write-cache buffer flushing on the device is turned OFF

It is usually important for removable disks, like USB disks. If the write cache is enabled on such a disk you get delayed writes, that means that even the you think the process accessing the disk has finished, it is still being written to. If you pull that disk in this stage you get file-system corruption. That is why you should always use the "Safely remove" tool in the taskbar and wait until you get the OK for removal. If the write cache is disabled on such devices you don't get delayed writes, so if the process writing to that disk has finished, for example your backup program, you can pull the disk out immediately with a much lower risk of file-system corruption.
