What did you expect to happen?

Please look at the documentation that was provided with that software.

Installing a drive overlay ENABLES access to the partitioning that it
supports. It does not require that either the boot drive or any other drive
in the system is configured with that partitioning. If the installation
overwrote the contents of the C drive that's because you asked it to set up
a managed partition on that drive. Partitions created while the overlay is
active may or may not be standard DOS partitions, depending on options
chosen. However, if such partitioning does exist then the overlay enables
those partitions to be recognised as if they were standard DOS partitions,
and they are accessible to the OS.

And, BTW, FDISK will remove that special partitioning provided the overlay
is not active when FDISK is run. If the overlay is active it will trap the
FDISK commands and either ignore them (most commonly) or convert them for
the different partition structure (eg, FDISK /Status). In some cases, when
FDISK is run without the overlay active it will refuse to remove the
partition because it doesn't recognise the type - that's version dependant.

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 .
