Write - Caching How to Enable and Disable Properties

If you have an external hard drive with a USB plug you should set it to be disabled as far as write-caching...that way it will be able to be unplugged without loss of data without stopping the hard drive.

Here's how to do it:


Turn Disk Write Caching On or Off

Right-click My Computer, and then click Properties.
Click the Hardware tab, and then click Device Manager.
Expand Disk Drives.
Right-click the drive on which you want to turn disk write caching on or off, and then click Properties.
Click the Policies tab.
Click to select or clear the Enable write caching on the disk check box as appropriate.
Click OK.


If you "disable" it you can unplug the external drive without loss of data
If you "enable" it you MUST use "safely remove hardware" or else will chance loss of data.
