Enable or Disable Disk Write Caching in Windows 10  

I'm not sure what may help other than seeing if formatting the SD may.

Hiyya Shawn mate doing this I only get what is in the picture and I am guessing I am missing something here.

Ok it is not attaching pics for me but it is the same as what milan had in post #7 - just those two options.

Hello John, :)

That's normal. It'll vary.

Is there a way for this to be enabled by default for all new devices?

Hello Bob,

I'm afraid it's only enabled by default for non-removable (internal) drives.

Update: Windows 10, version 1809 and later: Change in default removal policy for external storage media | Windows Support

I needed this option and wrote a little script to do it for all harddisks in the system. Maybe useful for someone?

Code:

For /f "Delims=" %%k in ('Reg.exe Query hklm\SYSTEM\CurrentControlSet\Enum /f "Disk" /k /s^|Findstr "Parameters\Disk"') do (
    Reg.exe add "%%k" /v UserWriteCacheSetting /t reg_dword /d 1 /f  
    Reg.exe add "%%k" /v CacheIsPowerProtected /t reg_dword /d 1 /f
)

EDIT mar 2021

Code:

For /f "Delims=" %%k in ('Reg.exe Query hklm\SYSTEM\CurrentControlSet\Enum /f "{4d36e967-e325-11ce-bfc1-08002be10318}" /d /s^|Find "HKEY"') do (
  Reg.exe add "%%k\Device Parameters\Disk" /v UserWriteCacheSetting /t reg_dword /d 1 /f
  Reg.exe add "%%k\Device Parameters\Disk" /v CacheIsPowerProtected /t reg_dword /d 1 /f
)

I'm a bit confused on the "enable write caching on the device" option that can be turned off even with better performance on. Is there a separate cache on the device than in Windows?

It really just depends on what type (ex: internal vs removable) of drive it is for which options are available.

"Better performance" must be selected instead of "Quick removal" to have the "Write-caching policy" settings available.
