An error was detected on device \Device\Harddisk3\D during a paging operation.

This device can be correlated with the "Inventory - Computer" page in the EventSentry web reports, where all hard drives are listed in the "Disks" section. The hard disk number from the event (e.g. Harddisk3) should correspond to the PHYSICALDRIVE number of the matching Device Id (e.g. [Device Id: \\.\PHYSICALDRIVE3]).

If the attached device is a SATA drive, then the drive identifier (e.g. WDC WD10EZRX-00L1KA3) can often be used to identify the drive during the POST phase.
