I recently upgraded Lenovo H330 desktop, removing dvd drive adding ssd drive and using Hitachi HDD drive for storage, only two sata 2 ports on mobo southbridge model H61, all was running well then turned on pc and no sign of Hitachi Hdd Drive in Disk Management or file explorer, I can see both drives listed in BIOS, in system summery, sata drive 0- SSD, sata drive 1- Hitachi HDD. and both listed in primary boot sequence. I unplugged the Hitachi from sata port 1 and plugged in the dvd drive, was able to load disk but nothing on the pc but again listed in the BIOS, would be grateful for any professional advise before proceeding any further.
