Today in this section we have
basically there will be theory.
For a long time we have had to endure
many inconveniencestR-DOSa, and
Sorry, the biggest inconvenience is -
This is the small capacity of a floppy disk. From
1MB of unformatted capacity
Only 6 KB are used! like this
Thus, we lose about 1Kb of in-
formations on every track! After all
system iS-DOS formats the disk
on800kb! that is, on every track
iS-DOS disk is used SKb -
5 sectors of 1Kb each.
A in tR-DOSeon sector 1 16
sectors of 256 bytes - that's all
BKb. The rest of the track
clogged with garbage.
It's time to stop this disgrace!
And we will put an end to this!
So, gentlemen programmers,
a grandiose one has appeared for you
work - completion tR-DOS to
8OOKb. However, let's return to theory.
How to increase the volume of each
track? The answer is simple! It is necessary to reduce
set the number of spaces between
sectors up to a certain mini-
myma, and increase the quantity
sectors on the track up to 20!
First, you need to write something like this
formatter, that's not the point -
no. And three times, we need to improve
thitR-DOS based on the driver principle
800 (on IBM).
Approximately the idea sounds
like this: DOS reads the disk, reaches
16(#10) sectors, reads and transfers
gives control to our driver
ru who is watching -is there
further on there is another sector (with number
17(#11)), and if any
then we read it, is there more? Let's read!
So, we considered the 20(#14) sector,
then 21 is gone, that’s it, return-
We go to DOS, it goes to the following
the best track, and with all this joy
we must not forget about the changes
nyhtR-DOS!
And also, if all this works out,
then you will need to rewrite
almost all disk utilities under
this is an expansion, since almost
all itilitax their disk pro-
procedures.
Who knows, maybe this is all
it shines, well, if not, well
an attempt is not torture.
