SYMPTOMS
Consider the following scenario. On a Microsoft Windows Server 2003-based computer, you have more than 10 disks installed. Additionally, one of the disks contains a bad block. This bad block generates an event message. However, a key element in the event message is truncated.

For example, an event message that resembles the following appears in the System log:

The device, \Device\Harddisk1, has a bad block.

This event message should appear as follows:

The device, \Device\Harddisk12, has a bad block.

Notice that &quot;\Device\Harddisk12&quot; is truncated to &quot;\Device\Harddisk1.&quot; Therefore, you cannot determine which disk is generating the problem.

This problem occurs in the event ID 7 and event ID 11 messages.

Note This problem does not occur on Microsoft Windows Vista-based systems.



CAUSE
This problem occurs because the size of the logged data, together with the driver name and the device name, is larger than the size of the port message. Therefore, event ID messages are truncated at the end of the message data.



RESOLUTION
To resolve this problem, use hardware diagnostics, or contact your hardware vendor.



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