SYMPTOMS
Consider the following scenario. On a Windows Vista-based computer, you start the Microsoft iSCSI Initiator service. Then, you log off an iSCSI target. In this scenario, the following event is written to the System log: Log Name: System

Source: PlugPlayManager

Event ID: 12

Task Category: None

Level: Error

Keywords: Classic

Description: The device  (SCSI\Disk&Ven_EQLOGIC&Prod_100E-00\1&1c121344&0&000000) disappeared from the system without first being prepared for removal.

Note This event occurs only if the target is an unformatted (RAW) volume.



WORKAROUND
You can safely ignore this event.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



MORE INFORMATION
In earlier versions of Windows, such as in Windows XP and in Windows Server 2003, you do not receive this error message.

This error message is incorrect in Windows Vista. To gracefully disconnect an iSCSI volume, log off the iSCSI target.
