Microsoft Windows may report event messages in the event log for various hard disk device issues using the following syntax:
In each of the preceding examples you need to translate the hard disk number to a physical drive on the system. You can determine the hard disk number by looking in the registry, but you need to know if you are using IDE drives, SCSI drives or a combination of the two. Disk Administrator will display the drives in the order they are enumerated on each controller and in the order that the controller device drivers are loaded. If you are using multiple controllers, the order in which they are identified is based on I/O port and controller BIOS address assignments.
- Run Registry Editor (Regedt32.exe).
- Locate, and then click the following registry key (for IDE-based devices):
HKEY_LOCAL_MACHINE\Hardware\Devicemap\Atdisk
Controller0 look at the controller address and interrupt.
disk0 look at identifier string for manufacturer and model#
disk1 look at identifier string for manufacturer and model#
Controller1 look at the controller address and interrupt.
disk0 look at identifier string for manufacturer and model#
disk1 look at identifier string for manufacturer and model#
- Locate, and then click the following registry key (For Atapi-compliant or SCSI devices):
HKEY_LOCAL_MACHINE\Hardware\Devicemap\SCSI
Scsiport0 look at driver, Interrupt, and IOAddress
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
Scsiport1 look at driver, Interrupt and I/O Address.
Scsibus0
Targetid0
Logical Unit Id 0 look at identifier and type.
- Using the "identifier" and "type" values, determine which entries are for DISKS and which are for other devices such as CD-ROMS, tapes, scanners, and so forth.
- Find each Type: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\harddisk5 find the 6th DiskPeripheral (zero through five).
- Make note of the SCSIPORT, SCSIBUS, and TARGETID# and use this to replace the defective device.
SCSIPORT is a SCSI controller.
SCSIBUS is a channel on the SCSI controller. Some controllers are dual channel and have SCSIBUS0 and SCSIBUS1.
TARGETID is the SCSI ID the device that is configured to use usually 0 through 6, with the initiator ID 7 representing the controller itself.
- If you have doubts about which SCSIPORT represents which SCSI Controller look at the driver, I/O Address, and Interrupt of the SCSIPORT entry and match it with the hardware configuration set on the controller.
- For IDE Devices, the drives are in master/slave configuration order on each controller.
