Event ID 51 An error was detected on device \Device\Harddisk2\D

Hello,

Event ID: 51 "An error was detected on device \Device\Harddisk2\D during a paging operation."

21 of April my customer got about 20 event id 51 and also on 16 of April. It has never happened before.
Witch drive is "Harddisk2\D"? I don't have any D:\

If I check drive manager I have the following drives:
Disk 0: Devided into two partions, C: and E. This is two drives in Raid1 config.
Disk 1: This is a Lacie USB drive with drive letter S:

Sata RAID controller is a: SI-4379-U0

Thanks in advance!

"\Device\Harddisk2\D" is the system's internal identification of the disk drive on which the error occurred. It is "somewhat unusual" that these internal IDs don't show up in the Disk Management snap-in; however, Microsoft has an article specifically on the topic of backtracking from the internal ID to a human-understandable device name:

Thanks, but this article describes Windows 2000... It doesn't seem to be the same... Under "HKEY_LOCAL_MACHINE\Hardware\Devicemap\" I can only find SCSI, but the computer has no SCSI...

Dr. Klahn

Windows 2000 treats RAID devices as SCSI, so the SCSI section of the registry relates to your RAID set.

Well, that's certainly interesting (KB244780). I would have expected error logging to be more accurate than *that*!

It also explains the truncated device-ID "\Device\Harddisk2\D". Good job on that, Sujith_Nair!
