The information provided by the diagnostics tests includes: error code, system serial number,
drive serial number, drive model, and drive firmware revision. Specific details of the drive failure
are not included.
When you run the diagnostics, the test results are stored in a log. After completing the test, you
can print this log to a local printer or save it to a file. Alternatively, before running the test, you
can configure the test options to send the results to a local printer or file.

1. Cable could be loose. Check cable connections.
2. The system may not have automatically recognized a newly
installed device. See reconfiguration directions in the "Hardware
Installation Problems" section. If system still does not recognize the
new device, check to see if the device is listed within Computer
Setup. If it is listed, the probable cause is a driver problem; if it is
not listed, the probable cause is a hardware problem.
3. If the drive is a secondary drive that has just been installed on the
same controller as the primary drive, verify that the jumpers for both
drives are set correctly.
1. The system is trying to start from a diskette that is not bootable.

has been damaged. Insert a bootable diskette into the diskette drive
and restart the computer.
3. Diskette boot has been disabled in Computer Setup. Run Computer
Setup and enable diskette boot.
The cable is not compatible with the drive type. Reinstall the second
Ultra ATA hard drive using an 80-conductor cable.
