Well since I always have a test machine on the bench
I decided to try out a few drive overlay utilites.

I had both maxtor and WD
and tried them both. Though one was called EZ install
and the other was EZ drive, they were really the same overlay...

But they did not appear to be the same as an EZ Bios utility I used a number
of years back.

Though installing the overlay took out any data on the drive which I setup
with as dos...
a second drive , D: was not affected one way or the other...
and whether or not the C: drive had an overlay on it or not...
nothing on the D: drive was in any way touched. I confirmed that all data
were there. (with or without the overlay)

I am going to have to try to find the old utility EZ Bios
and if I can find it anywhere...may see if that overlay is any different...
but I think they are all probably about the same.


Well, since I got up at my usual 4 am...
I am now at the end of my day...so no more experimenting tonight .
