I found another part of The Robot's problems. It has a bad RAID expansion. While the motherboard is handling the one of the DVD-RW, Main and Primary hard disk drives, the RAID is a special expansion card that fits into a slot and it controls the secondary, tertiary and another DVD RW drive. I need to have it because the motherboard only has 2 IDE (ribbon cable, old style) and 4 SATA ports soldered into it. Only one device uses and IDE in the Robot.
When a hard disk drive is more full, it slows down the performance of a computer. I've got around it by manually distributing the load of applications over all 4 physical disks. And I did it in a way that reduces the likelihood of two applications running at the same time being run from the same hard disk.
What's good to report is that the system is currently stable on three drives that it can run. Google Earth is attached to the Primary disk and it's files are available. This means that I'm now available to assist the American Discovery Trail with an east coast mapping project.
