Windows Disk Drive Device Names

I having been searching for many months for documentation about how to
decipher Windows hard disk device names.

For example, in the System Event log would be a message similar to the
following:
"The device, \Device\Harddisk1\D, is not ready for access yet".
Now D on this computer is not a hard drive. It's DVD-ROM. There are other
messages in the event log for the same date and time that say "dmio: Disk
Harddisk1 block 15375 (mountpoint E:): Uncorrectable read error"

It would make sense then that \Device\Harddisk1\D is actually a disk for
drive E: Is there any documents that explain these device names?

Post back with you find for \Device\Harddisk1\D

For example.

HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsi Port 0\
Scsi Bus 0\Target Id 0\Logical Unit Id 0
Value Name: Identifier
Data Type: REG_SZ
Value Data: Maxtor 91020D6

Normally there should not be names like \Device\Harddisk1\D.
Maybe this is actually \Device\Harddisk1\DR0 (or DR1 etc?),
or \Device\Harddisk1\DP(1) ?

Is there any documents that explain these device names?

Unfortunately these event log messages contain
low level disk names that look cryptic to users.

If it were \Device\Harddisk1\DR1 this means partition #1 on physical disk 1.

Then you can open Disk manager and look what driver letter(s)
mapped to this partition.
But this definitely is not a CD drive; CD-ROM usually has name
like \Device\Crdom0

That KB article was exactly what I was looking for. Thank you. Searching
the KB for "device names", "Physical device event message" and many other
keyword attempts wasn't producing results.

So according to http://support.microsoft.com/kb/159865

SCSI and atapi device are listed under
[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\

Device D would be the 4th SCSI device registy entry, identifed by
[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsi Port 1\Scsi Bus 0\Target Id
2\Logical Unit Id 0]

To complete the information in this thread, the computer has a motherboard
integrated Adaptec 39320 RAID controller and a IDE DVDROM drive. There are 3
drives attached to the 39320 controller, 1 drive is the main windows boot
drive, SCSI ID 0. The other 2 drives, SCSI IDS 2 and 3 are configured as a
striped volume by the SCSI controller. Disk Managment identifes the striped
volume as a single disk, Disk 1.

Here's my HKLM\Hardware\Devicemap\SCSI\ keys.

I did an Advanced Search for: Device\Harddisk1

With: The exact phrase entered selected.
