[sebhc] Z-37 Diag Disk

|Not necessarily.

I said it argues against it; I didn't say it was dispositive.

|Typically, format first writes tracks and sectors, then at the very end
|(after writing AND VERIFYING the tracks and sectors) writes an empty
|directory.
|
|What could be happening is that it's writing the tracks and sectors, but
|when verification fails, the empty directory and operating system structures
|(including the boot sector and it's disk parameter tables, for Heath
|systems) never gets written.

Perhaps I was unclear when I asked if the disk reads correctly on another
system.  I meant to ask whether the format was physically correct, i.e.,
whether sectors could be read; not whether it contained a valid file system.
If the answer is different I'll revise my diagnosis...
