Problem
How to check the exact version of the SCSI driver
Solution
If Backup Exec for Windows Servers jobs are reporting hardware errors such as I/O errors, semaphore timeout errors, and Event ID 9, 11, or 15 in the system event log, it may be due to the fact that the SCSI driver on the system is out of date.
In the example below, an Adaptec SCSI adapter and the corresponding driver have been used for explanation purposes.
In order to verify the exact model of the SCSI adapter installed on the system, do the following:
I. For Windows 2000 and Windows 2003
1. Open Control Panel | System (Figure 4)
Figure 4
2. Click on the Hardware tab, and then click Device Manager (Figure 5)
Figure 5
3. Select the SCSI adapter
Figure 6
To check the exact version of the current SCSI driver, follow the steps given below:
1. Click Start | Run (Figure 7)
Note: Ensure that the user logged in as the administrator or equivalent.
Figure 7
2. In the Open box, type drivers, and then click OK (Figure 8)
Figure 8
3. A list of files will appear (Figure 9). By default, the driver will be in \\winnt\system32\drivers.
Figure 9
4. Select the appropriate file related to the SCSI controller on the system. In this example, the file is AIC78XX.SYS (Figure 9).
5. Right-click the driver, and then select Properties (Figure 9)
6. In the General tab, check the size of the file (Figure 10)
Figure 10
7. Click on the Version tab, and then check the version of the file (Figure 11)
Figure 11
8. Make sure that the driver is up to date by checking the manufacturer's Web site, in this example, the Adaptec Support Web site
9. The driver can be found using the Registry Editor (Figure 12).
a. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<SCSI Controller>
For example, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aic78xx\ for the Adaptec Controller
b. String - ImagePath
c. Value Data - System32\DRIVERS\aic78xx.sys

Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.
If the file is of the correct size and version, and the errors mentioned in the beginning of this TechNote persist, please see the Related Documents section, and refer to Microsoft KB Article http://support.microsoft.com/kb/154690 .
