I'm not sure that head adapatives (I assume that's what you mean by "head selective") is what you should start with, though it can't hurt to import the donor adaptives into the patient ROM and try it.

What pclab was suggesting is setting the SAP control flag in ROM to have a max head of 0 or 1 and see if the drive can then initialize.

You can. I'm not exactly sure how the process works with DFL. I know PC-3000 can put the drive into boot ROM code mode and it'll never actually spin up the platters. So I don't have to remove the PCB to edit the ROM code.

Perhaps because you read at baud rate 921600 and now are trying to write back at a different baud rate other than what the drive was probably initialized at.

I personally always use rate 921000 for Grenada drives.
