acceptable... |
|
better... |
|
my
favorite one ! |

The program Copy II Plus from
Central Point Software is very simple and is chosen from
the menupage with the choice "Verify Drive Speed" -
there after you may choose the drive to be tested -
there a blank disk should be inserted - and striking the
key starts the test. The result is displayed as a
amount measured in milliseconds....
As the display explains you should get the drive within
a range from 198 milliseconds to 202 milliseconds and a
perfect result will be between 199,5
and 199,8 milliseconds.....
|
|
 |
|
 |
|
|
this is a view to the testpage and
the amount of milliseconds is flickering while changing
fast.... not very user-friendly..... |
|
Nibbles Away was in the old days also
a very common copyprogram with a testing option
- you choose DISK DIAGNOSTICS from the menupage.... and
then you choose the drive to be tested - and insert
there a blank disk .... |
|
Just
choose DISK SPEED from right side of the menulist and
then choose the drive to be tested either 1 or 2 from
slot 6 controller and the start with large range options
towards the options with smaller range starting with 1
and then switching to the option 2
( don't use
option 3 !
Its a special feature to crack a special
copyprotectionsheme ! )
I'll explain this
later in a special page related to cracking
techniques.... |
|
|
 |
|
 |
|
 |
|
|
The only
real good thing in this program is one fact: If
you have different drives connected to different
controllers in different slots you
may choose any drive connected to any slot ....
so you can test also
drives not connected to slot 6 ! |
|
After hitting the key the test
will start and allthough there still is a flickering
display of the
sectornumbers in hex - the big advantage is that at
least there is an arrow moving towards or away from the
center and that is much more user friendly bacause of
the optical display related to the turning of the
adjustmentscrew trying to get the arrow close to - but
slightly below - the center. |
|
The
option 1 is the more general one and its range is larger
... in fact the options are set that way that at Option
1 and selection of the range 1 in that option equals to
option 2 at range 3 so there is a kind of sieve from
Option 1 to range 3, range 2, range 1 and then switching
to option 2 with range 3 advancing to range 2 and then
the very smallest range 1 ! Up to my experience any
working drive will show up at first choice !
( If not - there is some other
more severe trouble there too- like damaged
compensation... ) |
|
|
|
|
 |
|
 |
|
|
|
|
The big
disadvantage with this program is that there is no
possibility to choose a range-scale
- so if your drive is far out of the range you just know
which side it went off the scale because the
arrow will be tagged to that side -
but turning the screw of the
adjustmentresistor with a tagged arrow at one side does
not give you any idea if you are running towards back to
the scale and the center or if its still just running
more far away ! |
|
A
bad drive might show up with something like this if also
the drivebelt is bad because the spread in speed shows
that the motor does not bring its power correct to the
spinningtable ( if belt becomes weak and flexible ) ....
if the drive belt is O.K. the line should be displayed
somehow something like the line in the second display
below....... |
|
|
|
|
|
|
 |
|
|
|
|
|
|
As
explained before you start with the COARSE ADJUST and
after pulling the speed by turning the adjustmentscrew
towards to the center and thereafter you may proceed the
the next step
choosing the MEDIUM ADJUST and finally performing the
FINE ADJUST...... |
|
|
|
|
|
|
 |
|
|
|
|
|
|
If
your display looks somehow similar to this and is close
to the center you may switch to option 2 : OPTIMUM and
then again work ahead from COARSE ADJUST to FINE ADJUST. |
|
|
|
|
|
|
 |
|
|
|
|
|
|
Its
easier to follow up the line if you allways choose the
Option of only taking 1 sample per
line .... taking more
samples only makes sense, when adjusting the
compensation - but not the drive speed ! |
|
|
|
|
|
|
 |
|
|
|
|
|
|
This
displays a perfectly adjusted drive at Option 2
( OPTIMUM ) and FINE ADJUSTMENT with 1 sample per line !
This drive is adjusted to something about 0,1 % slower
than the center. That "slight little bit slower" was
explained above at the section with the diskpictures ! |
