DIC is a tool to create an file image of a floppy disk. DIC reads the contents of the floppy disk via the appropriate device (e.g. "trackdisk.device" for DF0:) and writes the data to a plain file in the actual directory. The name of disk image file created will be "Disk.1", where "1" is the number of the disk read. The disk number is increased after each disk read. Using the Name option a different name for the image to create can be specified.
DIC can also read other devices like RAD:, PC0: or DS0: and high density disks.
If one track of the floppy disk cannot be read correctly and DIC has
been started via an interactive terminal (e.g. CON:), it will ask to either
skip the failed track or to try to read it again. On noninteractive
terminals these tracks will be skipped by default.
For skipped tracks the appropriate area in the image will be filled with the pattern "TDIC". So it is possible to identify the read error later.
DIC can also read disks partially by using the option SIZE/K/N. If used DIC will ommit the data after the specified size. This may be useful if the last tracks are unused.
Tracks can be skipped using the option SKIPTRACK/K/N. This is very useful to create images of disks containing a disk based protection (e.g. RN-Copylocks on track 1).
If the option PEDANTIC/S has been specified DIC will quit immedately if a track is unreadable.
DIC can be interupted at any time by pressing Ctrl-C.
To use DIC interactively:
the device from which DIC will read the disks
|NAME||name for the image to create, if specified DIC will not name the image "Disk.1" and so on, but uses the specified name. this option sets FIRSTDISK/K/N and LASTDISK/K/N to 1, which means that only one disk will be read|
the tracks specified will not be read, the appropriate area in the disk
image to create is filled with the pattern "TDIC", the following
table shows some examples to illustrate the flexible possibilties to
|SIZE/K||the size of the image to create, useful if there is an unused area at the end of the disk, if size is larger than the physical image size it is ignored|
number of the first disk
|PEDANTIC/S||if specified DIC will immedately quit if a track cannot be read, should be used in install scripts|
