Hey SIW, thank you for the VERY detailed explanation, to a confused soul like me, EVERYTHING helps! One very minor correction to your narrative, the Lenovo system is s Desktop, the (Toshiba) Laptop is what I used to "test" the External Drive but everything that you described about the "Laptop" (really a Desktop) remains the same and gives me a better understand of "what's what".
I'm attaching another scan
9 22.jpg (223.4 KB) that I took a few minutes ago where Disk Manager shows Disk 5 to contain the infamous "Z" Drive with 58.42GB AND 16.11GB of Unallocated Space which is DIFFERENT that it was yesterday when it was labeled EISA.
Just to keep everything straight, this morning I REMOVED the External Drive from the Desktop and plugged it into a Laptop. After I checked that the contents of the External Drive were intact and that "only" 58.42GB "appeared" when I opened MY Computer on the Laptop, I plugged it back into the Lenovo Desktop and the Lenovo system recognized the External Drive as "new hardware".
Again, I am not a teckie so this is my "novice assumption", if I FORMAT the Partition that I inadvertently created and that I want to eliminate, I will be able to EXTEND the "Z" Drive and add the additional space (that is currently Unallocated).
If this is correct, I could appreciate help as to HOW to Format the Unallocated Space since FILE and ACTION on the Pulldown Menu do NOT offer this option.
If this assumption is WAY off line, then I would appreciate your thoughts / suggestions / advice.
Thanks again for ALL your help guys,
Pain in the &^%$, Bob
