I was swapping boot drives to try some experiments, and when I plugged in the SSD drive, the system would no longer boot. The BIOS no longer detects the drive. I swapped cables with a known good SATA cable. Same result. if I plug in the Test OS drive, the system boots fine.
Here's the weird part. On a different system, that SSD is detected and I can do copies and moves no problem. What's my next step?
