BTW, I assume that you are aware that the prevailing opinion is that it is not possible to reconstruct a Toshiba ROM.
I prefer to think that it is very difficult without the orginal, but having a corrupted ROM, I think it could be feasible to get it, although I assume that I am not the best person, not even close.
My approach to this problem would be to determine which CPs are necessary to reach the SA. To this end I would take a working drive and manipulate those CPs which appear to be head or media related. I would limit my changes to head #0, and I would vary each parameter, up and down, until the drive ceases to boot. This will tell us the sensitivity of each parameter.
I would also import a foreign SN or MN CP, just to see how the drive identifies itself.
