What does ImageCopy do?
I use ImageCopy mainly to store images of diskettes onto my hard disk in
order to write them back onto the same kind of diskettes whenever I am
able to. Currently only disk drives A: and B: are supported, I guess I
could change that whenever the demand for any kind of disk drive arises.
The following diskette formats are supported:
3½" - 720 KB and 1.4 MB
5¼" - 360 KB and 1.2 MB
I wrote ImageCopy in order to be able to copy diskettes 1:1 without the must
of having the according amount of empty diskettes at hand, instead at least
some kind of PC or notebook hard disk drive. The disk images can be copied
back to diskettes whenever I please.
ImageCopy is menu-driven without any fancy stuff. After reading a diskette
you have the possibility to compress the image, whereas the result of the
compression depends on the amount of data stored on diskette. After
compressing ImageCopy then decides to either keep the compressed version of
the image or the original. It _can_ happen that compressed images become
larger than originals, especially with very dense diskettes.
ImageCopy "remembers" the diskette size of the original, so that it will ask
for the according diskette type when writing the image back to diskette at
a later time. Images are first decompressed in case of image compression. You
can have ImageCopy format a diskette for you first before writing the image
back.
What does ImageCopy not do?
ImageCopy _cannot_ copy diskettes with sector oriented copy protection
mechanisms. It is also not possible to copy images to diskettes that do not
match the size or capacity of the original, e.g. you can't copy the image
made of a 5¼" 1.2 MB diskette on to a 3½" 1.4 MB diskette (otherwise it
would not be an image anymore).
ImageCopy is free to use, I ask not to sell it. I regard it as FreeWare until
further notice. Should any problems or erros arise, or should anyone just
want to give his piece or make suggestions, feel free to contact me via
