I have the following event in Event Viewer:

"The driver detected a controller error on \Device\Harddisk6\DR19."

Log Name: System
Source: Disk
EventID: 11
Level: Error

How do I know what disk this is referring to? I am reasonably confident that it is a plugin USB memory stick, but want to be sure it is not one the of the main HDD's. When I plug a USB stick into the slot, diskpart shows the arrival of "Disk 6". I am presuming that Disk 6 corresponds to Harddisk6 in the controller error, but I don't like assumptions.

Method 1 Computer Management:
Open Computer Management (compmgmt.msc)
Expand Storage
Click on Disk Management
Right-Click on your hard disk(s)
Review the General tab and the Location field

Method 2 Registry Editor:
Run the registry editor (regedit.exe)
Drill down to the following path:
HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsiport0

Use the "identifier" and "DeviceType" values, determine which entries are for DISKS and which are for other devices such as CD-ROMS, tapes, scanners, and so forth.

Scisbus0
Targetid0 > Logical Unit Id 0 look at identifier and type.
Targetid1 > Logical Unit Id 0 look at identifier and type.
Targetid4 > Logical Unit Id 0 look at identifier and type.

Scsibus1
Targetid0 > Logical Unit Id 0 look at identifier and type.
Targetid1 > Logical Unit Id 0 look at identifier and type.
Targetid2 > Logical Unit Id 0

...

Find each DeviceType:REG_SZ:DiskPeripheral entry under the Targetid#\Logicalunitid0. Each one found equates to a drive in Disk Administrator and also to a \device\harddisk number.
To find \device\harddisk6 find the 7th DiskPeripheral (zero through five)
