HEAD ACHE
(C) Shaitan / Stars of Keladan
How much is a headache every spektrumista caused the problem
goals. But do not think that I am very vulgar or what I'm
talking about Dragon kites. This paper thesis is testing
drives, as well as setting the magnetic
head drives.
Everything started with the fact that I once
acquired a very useful book publishers "SOLON", "Repair Disk
Drives" from the series "Repair", which presents scheme the
most ubiquitous in Russia drives both domestic and foreign
production. In this book also present methods and ways of
eliminating the most common problems, and
just described to you all known mikruha VG93.
But the main fichey this book is
what it was supposed to be attached
CD with test programs oriented towards the Spectrum.
Since that time, the date of purchase
of the booklets (and has been more than chetereh
years), I tried to find this particular program, which was
described in this book. During this time, I came across only
two similar programs, but do not substitute
each other. This program from MagicSoft'a
and from ALK / Stars of Keladan.
And now, four years later, the program of "Solon" falls into
my hands. AND I just wanted to share it with you. Thus,

That you will not confuse give a full description of the
program of the above book.
The main purpose of the program - a task
drive teams to its effective management. In addition, the
program allows you to format the disk in a format
TR-DOS, write to disk or to a specified track a constant
or random numbers, check the drive for compatibility, to
measure the velocity rotation of the disk, etc. The program
works online, to perform
necessary commands to type a number,
standing in line to the left of the team.
Additional data to perform
command requests in progress, in parentheses as a hint
displayed no specific number, or
range of numbers from which to
pick a number for the command.
The main menu consists of three
points:
1.Vybor drive
After the introduction of storage facilities (0, 1,
2 and 3) you choose to address the drive to be tested or
repaired. After that, the program must return to the main menu.
2.Testirovanie drive
Submenu of the item main menu
consists of the following lines:
1.Formatirovanie drive
You format a disk
format TR-DOS (2-sided, 80 tracks).
2.Zapis constant disk
Once you enter a constant
of this interval, the program will record all the tracks on a
disc this constant.
3.Zapis random number
disc
The program writes to the disk pseudo-random sequence. Such
record need, when you test
drive for compatibility.
4.Zapis constants on the track
After entering the track, the surface and the number of the
program will record for a given address you code numbers,
you specified
5.Chtenie Disk
The program will read that you installed the drive and will
show the track number and sector, which will not be able
pr6ochitat.
6.Chtenie track
After you specify the track number and
program reads the track surface
and if the reading is executed without error,
come to the main menu.
7.Izmerenie rotation period
Disk
This feature serves to monitor
performance and tuning servo drive. Normal speed
rotation of the disk 200 + /-3ms (300 rpm)
8.Prosmotr track
After entering the desired track number
and the surface of the program is reading
and displays the contents on the screen
9.Proverka compatibility
Quickly and in real
check the drive for compatibility,
or monitor its performance after adjustment. Consistently
Read 2, 10, 40, 78, 75, 50, 15, 0
tracks and displays an error message.
0.Formatirovanie track
Writes to the specified path and
surface of the code of "units" without partitioning
it sector and guidance control
amount. This provides a waveform without interference.
SPACE.Vyhod (in main menu)
3.Vypolnenie team
Submenu of the item main menu
consists of the following lines:
1.Vyhod to 00 track
2.Shag forward
3.Shag ago
4.Pusk drive motor
5.Stop drive motor
6.Vybor surface
7.Zagruzka head
8.Razgruzka head
9.Zapis tracks in a loop
0.Chtenie tracks in a loop
SPACE.Vyhod (in main menu)
Comment on the team name is not
necessary. Using these commands, you can identify and
troubleshoot the drive. In addition, they allow you to
competently perform operations on the replacement, adjustment of
block of magnetic heads, replace the sensor
and stepper motor.
