Now I have a different problem. It might warrant a new thread but I am going to continue this one.
After achieving the reconfiguration show in the last snip above, I shut down and installed a HDD that I acquired. It is identical to the other two that have been in my computer.
After getting it installed (incorrectly I later discover), the system would not boot. After some frustration and cussing under my breathe at persons not to be blamd (or to be named), I gathered myself together and came to realize that 1) the recently introduced HD had an operating system on it (maybe not the cause of my problem) and 2) I installed it into SATA1. I have had the HDs in SATA2 and SATA3 which is where they were before back in the very beginning.
Right now, all I have connected is the primary drive in SATA2. My Data drive is disconnected as is the new drive.
My question is where must I install the three drives without creating more problems.
Is it necessary to have the drive with the OS (C

installed in a lower numbered SATA position than the others?
Do they need to be sequential?
Does it matter where I install the new drive. I have openings (with cables) in SATA 1 and 2 and SATA 5 and 6.
