Drive not found (identied).
Cause Solution
Cable could be loose. Check cable connections.
The system may not have automatically recognized a newly
installed device.
See reconguration directions in the Solving hardware installation
problems on page 62 section. If the 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.
If this is a newly installed drive, run the Computer Setup utility
and try adding a POST delay under Boot Options.
Drive responds slowly immediately after power-up. Run Computer Setup and increase the POST Delay in Boot
Options.
