To unplug or eject devices
In the notification area next to your task bar, double-click the Safe Removal icon. Safe Removal displays a list of Plug and Play devices currently attached to the system that support safe removal.
If you do not see the Safe Removal icon, your device does not support safe removal, and you cannot unplug or eject your device using Safe Removal.
In Safely Remove Hardware, select from the list of devices the device you want to unplug or eject, and then click Stop. This tells the system that you will be unplugging or ejecting the device.
In Stop a Hardware device, click OK.
A notification appears stating that it is now safe to unplug or eject the device.
Unplugging or ejecting a device that supports safe removal without first using the Safe Removal application to warn the system can cause data to be lost or your system to become unstable. For example, if a device is unplugged during a data transfer, data loss is likely. If you use Safe Removal, however, you can warn the system before you unplug or eject a device, preventing possible loss of data.
For removable storage devices that can safely be removed while the system is on, the system disables write caching by default. It does this so the devices can be removed without loss of data. When write caching is disabled, however, the system will likely experience performance problems, so be sure to enable write caching when you have finished removing the device.
