Hi again folks!,

I hope you like this small utility program. It was written in C language and
some assembly language.

It is a resident monitor for all interrupt 13h activities and provides a
log in memory for all disk errors. Also it shows a status line at the top of
the screen of the activities. The buffer holds approximately 40 errors and then
wraps around to the beginning.

To install the program, copy the file DISKTRAK.EXE to your root directory
or your search path and just enter "DISKTRAK" followed by . Make this
your last resident program.

You will see the time in the upper right corner of the screen and during
your next disk I/O operation, the status line will appear on the top of the screen.

The cpu registers and the floppy disk controller status registers
in the log are shown in hex. The values in the status line are all decimal.

Please feel free to share this program with your friends but
only in it's original file name "DISKTRAK" and NO MODIFICATIONS!.


Here is a description of the error messages, they will show when
you ask for the dump of errors, "DISKTRAK d" , if any.
