- This is a program that I have found useful in several occasions: when you
- have to transport files on floppy discs (e.g. from Stanford to Europe) it
- is better to be sure that all what you have copied is readable before to
- slip 7,000 miles away from the original material. This program, named DT
- for Disk Test, tests the whole disc: at first reading all cylinders one
- by one, to be sure that the disc itself is reliable; then reads, record
- by record, all files on the disc. This last step can be take long time if
- you have several files; but it is, as I think, the most important to check
- the data reliability.
-
- DT has been written specifically for floppies: to check hard disk cylinders
- there are diagnostic programs that usually come with them; and to check the
- readability of a subset of the files you have somewhere, you should try the
- program VERIFY that you will find in the DevWare collection. I decided
- to mimic the aesthetic of the DT program from Peter Norton (in the IBM-PC
- Norton Utilities); but I avoided the Peter Norton's option of a switch in
- the command line to skip the cylinder test or the file test: in my opinion
- both phases are essential and not too much time consuming, so the user
- should perform both.
-
- To run this program from the CLI, enter DT DFx:, where "x" is the floppy
- unit number (the colon can be omitted); clicking on the DT icon from the
- Workbench will open a window on which you will be prompted for the unit
- to test. The output is self-explaining.

- A thank to:
- - Commodore: for the Amiga;
- - Lattice, Inc.: for Lattice-C v5.04;
- - ASDG, Inc.: for CygnusEd Professional;
- - Joel Swank: for VERIFY (but I did not borrow almost
- anything from him);
- - Peter Norton: for the original DT.
-
- You are free to use, modify and freely distribute this program; but you
- must not charge money for it, and leave my name and my notes as they are
- (yes, I mean in the same bad english you laughed at). If you will modify
- DT and will take care to send me the changed program, you will make me
- happy. My address can be found in the source header.

- Have fun !
