Drive not found (identified).
Cause Solution
Cable could be loose. Check cable connections.
The system may not have automatically recognized a newly
installed device.
See reconfiguration directions in the
Solving Hardware
Installation Problems on page 102 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 Advanced > Power-On
Options.
The device is attached to a SATA port that has been hidden in
Computer Setup.
Run the Computer Setup utility and ensure Device Available is
selected for the device's SATA port in Security > Device Security.
Drive responds slowly immediately after power-up. Run Computer Setup and increase the POST Delay in Advanced >
Power-On Options.
