About disk errors...
The leading developers of commanders for real zx have a proposal
use the following format to store errors on floppy disks.
If an error appears, then when formatting into sectors 9 - 15
track 0 write bit by bit yes/no error in sector nn /
track mm.
That is, if, for example, there is an error in track 1 sector 0, then
the zero bit in sector nine of track zero will be, for example,
one, and if there is no error, then there will be zero.
For example, after formatting we have five on the first track
bad sectors:
track00:
0 1 2 3 4 5 6 7 8 9 a b c d e f
b b g b b g g g g g g g g b g g
b-bad, g-good sector;
The first byte of the eighth sector of the zero road will have
value %11011000 , i.e. 1-bad, 0-good, hence the second
byte %00000100 and so on.
This method is suitable for storing information, but for
These discs cannot be used to read/write programs.
suitable, will have to remake the rull tr-dos!!!
Although we are deprived of such things as launching programs, but this pile
fucking disks (at the very beginning!!!) can be clogged
software!!!
