Using the SCSI Disk Utilities
To access the SCSI disk utilities, select SCSI Disk Utilities from the menu that appears when you start SCSISelect. When the option is selected, SCSISelect

When you select a specific ID and device, a menu appears, displaying the Format Disk and Verify Disk Media options.
l
Format Disk — Runs a utility that allows you to perform a low-level format on a hard-disk drive. Most SCSI disk drives are formatted at the factory and do
not need to be formatted again. The Adaptec Format Disk utility is compatible with the majority of SCSI disk drives.
l

Troubleshooting for Windows NT
The boot manager for Windows NT contains recovery logic to allow you to return to the last known good configuration. If you have changed your host adapter
configuration and Windows NT no longer boots, perform the following steps to recover it:
1. Undo any hardware changes that you have made to the system since it was last operational.
2. Reboot the system. Watch the display carefully during start-up. If the following message appears, press the spacebar, type l at the next screen, and then follow
the instructions on the screen to continue booting with the last known good configuration:
Press spacebar NOW to invoke the Last Known Good menu
3. When your system is operational again, check all of the hardware and software configuration changes that you want to make. Look specifically for conflicts with
parts of the existing system configuration that are not being changed.
If you cannot determine the source of the error, see, "Getting Help" in the Installation and Troubleshooting Guide for instructions on contacting Dell for
technical assistance.
NOTICE:
The Format Disk option destroys all data on the hard-disk drive.
