- 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 can be used either menu-driven or via command line, 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.
-
- A small tip for compression: Diskettes that are not completely full
- allow better compression ratios when they are first formatted before
- written to. Erasing full diskettes with "DEL *.*" doesn't do the trick
- since DOS only marks the files as deleted inside the FAT, whereas the
- data still resides on the diskette.
-
- 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
- CompuServe. My CIS ID is 100065,1602 .
