Additionally, if the disk is formatted by using the NTFS file system, a Warning event that resembles the following may be logged in the System log: This issue may occur if the disk is "surprise removed." For example, this behavior may occur if you remove the disk without using the Safely Remove Hardware icon in the notification area to stop the disk first. This issue may occur even though the disk uses an interface that supports surprise removal, such as a universal serial bus (USB) interface or an IEEE 1394 interface.
Note If your configuration requires that you frequently surprise-remove the disk, we recommend that you do not enable System cache mode. For more information about System cache mode, click the following article number to view the article in the Microsoft Knowledge Base:
