Enable, Disable Disk Write Caching in Windows 10/8/7

Disk Write Caching is a feature that improves system performance by enabling write caching on the device. It is a feature, which is available on almost all disk drives these days. The benefit of Disk Write Caching is that it allows applications to run faster by allowing them to proceed without waiting for data write-requests to be written to the disk.

Let’s say you save a file. Now when you save it, Windows makes a note that you want to save the file on your hard drive. This information is saved temporarily in Windows memory, and it will write this file to hard drive later on. After the file is written to the hard drive, the cache will send an acknowledgment to Windows that the file has been written to the hard drive and it can now be safely removed from cache.

Disk Write Caching does not actually write data to the hard disk drive, It occurs after some time, after some time. But in case of a power outage or system failure, the data can get lost or corrupted. So while disk write caching may increase system performance, it can also increase the chances of data loss in case of power or system failures.

If you see the following error messages, you might want to check if disabling Disk Write Caching helps:

  • Windows Write Delay Failed

  • Delayed Write Failed.

Disable or Turn off Disk Write Caching

If you wish, you can turn off Disk Write Caching on your Windows computer. You can enable or disable this feature through the Disk Management snap-in.

Follow this procedure to disable Disk Write Caching. Open Computer folder > C Drive > Properties > Hardware tab > Select the Disk Drive > Click on Properties button > Policies tab.


Here you can uncheck Enable write caching on the device. Click Apply/OK > Exit. On removable USB devices, you may see the option as ‘Quick removal’¬† instead.

You can also do the same by opening Device Manager, right clicking on the Disk Device Drive and selecting Properties > Policies tab.


Do note that after you disable Disk Write Caching, your hard disk may perform a bit slower and may affect the overall system performance of your Windows computer.
