The front chassis cable on your SR665 has gone, and now the drives aren't talking to the controller. You need the BP1 front backplane kit, not a generic SATA ribbon that might not seat properly. This is the Lenovo ISG 2.5" chassis front BP1 SAS/SATA cable kit for the ThinkSystem SR665. Straight swap, correct pinout, drives online again. No guesswork
