SATA RAID Controller Link not present amber light. One SATA HDD was amber light at the front, so have replaced with another SATA HDD, now the HDD Front light is green. However i noticed on the SATA RAID Controller card there is a tiny amber light on LInk not present (under RAID Controller connector). All other raid controller card leds are green. All leds on mobo are green. Windows server 2008 (OS) is blue screening with 0x0000024 error. Repair install cant see Operating systems.
