Good evening.
I have 2 st1000dm003 seagate drives in good health which I was planning to run in raid. Initially both showed the same capacity of 1.00TB/931.51GiB. Firmware for the first one is AP18 (apple) and the second one was CC44. So the second one I updated to CC49 (which was the recommended update) and it changed the capacity to 997.93TB/929.39GiB.
While the loss is minuscule - I was still curious - but could not find anything online on the issue. Does anyone have any ideas?
