Let me ask you a few questions regarding the terminology you used
to describe your issue. You used the term "Image" to describe the
method used to transfer the data from the old HD to the new one.
Generally speaking an image file is a "snapshot" of a disk's
critical file information. It saves the disk's boot record, file
allocation tables and root information to a file. The file is
used to reconstruct a HD if you were to accidentally format it.
The software that most HD manufactures used to accomplish the task
that you described was a program that reads the data from the old
HD, one bit at a time (bit for bit and byte for byte) and then
writes that data to the new HD in exactly the same manor, one bit
at a time. It can be done at the MsDOS level or from within windows
at a DOS level. The purpose of doing it that way was to preserve
the "long file names". The first thing that you had to do was
install the new HD in the computer as a slave drive. then run the
provided program to accomplish the file transfer. In a sense it's
a carbon copy image of the original HD data. If there was a file
in the root directory of the old HD with the name "Image.Dat" it
would have been transferred to the drive. It wouldn't be a valid
image file because of the different architecture of the two HDs.
The program does not erase or remove the information from the old
HD. When the program was finished with the data transfer you would
remove the old HD and set the new HD as the primary master. Turn on
the power switch and let her rip.
The files and folders on the HD are recorded in the DOS "eight
plus three" naming convention. An example would be the folder
"Program Files" on your HD. That is a Windows long file name.
That same folder has a DOS name of "PROGRA~1". If you right click
on that folder with your mouse, using explorer, and select
"Properties" from the context menu it will show "MS-DOS name:
PROGRA~1". Go ahead give it a try.
I truly don't believe that you have anything to worry about.
If I were you and had the same concern, I would contact the HD
manufacture with my question. They made the HD and wrote the
software so they would be in the best possible position to answer
