This problem occurs because the Aic78xx.sys driver chosen during the application of Service Pack 4 is not compatible with the computer's Adaptec SCSI controller.
This problem can be corrected by replacing the existing Aic78xx.sys driver, located in the %systemroot%\Winnt\System32\Drivers folder, with the Aic78xx.sys driver from the i386 directory within Service Pack 4.
Windows NT 4.0 Service Pack 4 contains the following Aic78xx drivers:
Aic78xx.sys 26,704 bytesTo determine which Aic78xx.sys driver is in use, and to copy the correct driver, depends upon the file system on the Windows NT boot partition (where %SystemRoot%\Winnt resides).
Aic78xx.001 56,272 bytes

The Aic78xx.001 file of Service Pack 4 is only placed on the computer if %systemroot%\Winnt\System32\Drivers\AIC78xx.sys has a revision between x.x.1382.x and x.x.1420.x.
