Britec Tech Support Forum

Device manager/hard drive/Policy tab that allows you to check the box enable write caching is greyed out and the hard drive is a fixed hard drive so im not sure why this is happening

If it's grayed out then the SATA driver does not

support 'SCSI pass thru', so Windows cannot send
the right commands to the disk.

1. Backup Data
2. Check Hard Drive Health
3. Change SATA cable
4. Could be Hardware issue.
5. Try Dskcache utility 
   

You can use this utility Dskcache.exe  Obtain the Dskcache.exe tool to configure the "Power Protected" Write Cache option

How to enable Write Cache by command script:


c:\dskcache.exe +w
exit

Also you can add this script to startup scripts:

Start gpedit.msc and use
Local Computer Policy\Computer Configuration\Windows Settings\Scripts

Its greyed out due to an intel driver that takes over the policy option and the hard drive its self. I believe its called the intel matrix storage.
