As you didn’t give us the make and series of the SSD (or HD) you installed in your system I can’t verify if it will work in your system. Let me explain here … Your system only has a SATA I (1.5 Gb/s) interface so only drives that offer SATA I will work here. So if the drive you have spec sheet only lists a single fixed speed of either SATA II (3.0 Gb/s) or SATA III (6.0 Gb/s) it won’t work here! Now some drives offer auto SATA port speed sense technology so it can match up with the systems SATA port. But! Not all of these drive support SATA I (1.5 Gb/s) so you need to review the fine print in the spec sheet to be sure. Until you address the drives SATA speed issue tracking down the other odd behaviors won’t get you going here. As the brick mason said: “Until you have a sound foundation building the house is pointless!”
