SYMPTOMS
When you delete a hardware volume shadow copy that was created with the Volume Shadow Copy Service on a Microsoft Windows Server 2003-based server, an event that is similar to the following may appear in the system event log:

PlugPlayManager

Error None 12

N/A

The device 'Manufacturer Model (C) SCSI Disk Device' (SCSI\Disk&Ven_Vendor&Prod_Product_(C)Vendor&Rev_2001\4&13376f61&0&1017) disappeared from the system without first being prepared for removal.



CAUSE
This issue occurs because Windows Server 2003 identifies the hardware volume shadow copy in the same way that it identifies a hard disk. Therefore, when you delete a hardware volume shadow copy, Windows Server 2003 generates the same error message that is generated when a hard disk is removed.



RESOLUTION
You can ignore this event in the system event log if you have deleted a hardware volume shadow copy from your computer.



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