wasn't the x040 using the 2031 layout, too? The 1541 and the 2031 layout
differ in the length of bytes between end of header and start of sync of
the data. Writing a 2031 disc with a 1541 can result in a sync (from
the 2031), followed by an undefined area (caused bsy setting the R/W head
from reading to writing) and then a new sync mark (from the 1541).
If the rest of the 2031 sync is long enough to be recognized as a sync
marc and the undefined area contains a zero bit, you have a problem
that the data cannot be read. From what I heard (never owned a 2031)
this indeed does happen.
Spiro.
