Connection - Configure the hard drive of the Shadow Monitor.

         Software Connection


  If the interface part is in order, in
the process of self test hard
drive computer "hangs", waiting for the "answer" from the 
device, and upon receipt of this the answer is trying to 
determine the parameters of the disc. To obtain these 
parameters is a procedure that also requires some time. Total 
playing time at first inclusion of the hard drive should not 
exceed a few minutes. If this time more, it means the disc is 
not in order. 


  Successfully identified the hard drive issue
on the computer screen label of the form "IDE / AT
1030 MB Hard disk found ", where instead of
1030 will be a definite program
the amount of your hard drive. If this volume does not 
correspond to the actual amount of disk it means the disc 
incorrectly reported Program and currently requires manual 
configuration parameters, as below. Next show three lines of 
information with the manufacturer. The first line contains both

Still interested, then press (and not
release) "Reset" button, but after necessarily produce a "cold" 
start computer (reset with holding down the keyboard by 
pressing "Left"). 


  If the internal tests and Auto identification hard drive is 
successful, computer goes to standard menu OS

BASIC. Further action on the connection
hard drive should be carried out in the Shadow Monitor 
(remember that the entrance to the TM by briefly pressing on

button Magic).


  If you have an old and slow disk, then
he may not have time to do all the internal tests to verify its 
start time monitor program, in this case on a computer screen 
instead of the above posts there any error message (most 
likely, "Hard disk data not ready "or" Busy not found "). In

this case, try not turning off the power
produce a "cold" start your computer.
If it does not help (still appearing
error message), then check again
hardware connection of the controller and SMUC
hard drive. It is possible that such a copy of the disc 
requires manual setting of parameters, or it will not work in 
general. 


  So, we push ourselves to the Magic and
Menu Shadow Service Monitor. Choose
menu item "Hard disk utility", as it
"Set Up".


  As the name implies, automatic
identification of the hard drive is
automatically. Actually, the first automatic identification has 
already occurred (see previous chapter). Or at least,

trying to happen. The results of the process
displayed in the menu items Cylinders, Head and Sector, which 
show the "geometrical" parameters of the hard drive, 
respectively, the number of cylinders, heads and sectors. These 
parameters ideally must comply with passport hard disk 
parameters. You can once again on Just in case, follow the 
procedure Autoconfiguration hard drive by selecting item "Auto 
detection hard disk". "Geometric" sizes should remain stable 
and unchanged. 


  So, if all goes well, the data found agree with those 
expectations, then can allow identification at the start

(It is enabled by default, the menu item
"On start" in a state of ON), and immediately move to test the 
hard drive (remember that the flag ON is the inclusion action, 
and select OFF - OFF. And do not be confused with the English 
preposition "on"!). In Otherwise, go to the manual 
identification of the disc. 


  Actually you should enter in paragraphs

  Is that the parameters of the hard disk is not

all indications Auto identification was

  So you enter the actual parameters

program Monitor Auto identification is not carried out at the

in a state of "OFF". 


  By the way, starting with version 4.00 of the Shadow
Service Monitor the opportunity to work with hard disk mode 
Logical Block Address (LBA). What does this mean? Early models 
of hard disks were obtained from computer coordinates the 
sector in the form of a cylinder / head / sector. These 
calculations had to produce a computer program. But with the 
advent of E-IDE interface such way of addressing the hard drive 
space becomes inconvenient, since used

hard drives over 504 MB. Therefore, all models of hard drives 
with interface E-IDE can get just a logical sector number in 
the 28-bit form, and all the necessary calculations have been 
produced for electronics of the hard disk. This allows three 
times the rate of increase of machine with the hard disk. But 
since Shadow Service Monitor can not yet determine the possible 
mode LBA, it is worth try to install it manually and check the 
hard disk. If all ok - you can leave them in

state "ON".


  Any changes to settings in the menu of the Shadow Service 
Monitor only until the moment power is turned off, or "cold"

Reset the computer. After that, everything is restored to the
