Please do not post questions about data recovery cases here (use this forum instead). This forum is for topics on finding new ways to recover data. Accessing firmware, writing programs, reading bits off the platter, recovering data from dust...

I'm wondering if the following methodology would enable a missing ROM to be reconstructed, assuming there existed a suitable burn-in/selfscan procedure for the target model.

    Transplant patient heads to donor drive
    Run burn-in/selfscan against donor drive
    Return patient heads to patient drive
    Transfer new burn-in adaptives or entire PCB from donor to patient
    Edit serial number, etc.

Can't see it working at all using SS, however I would love to read about someone trying! There are potential methods, much the same as Brute-Forcing passwords.

Fujitsu MPG adaptive values could be brute-forced :D that's for sure.


Or, just talk nicely to the manufacturer and they could supply original "adaptives"...IF they really wanted.

This would only matter mainly on Seagate F3 and Toshiba as there are other methods for other brands that wouldn't require to remove the heads like trying several ROM files on WD and getting the copy from the platters.

On Seagate F3 and Toshiba you wouldn't be able to SS at all you would gain nothing, unless you have some sort of factory code to run the SS or to regen the adaptives on those drives to start with.

So you would be back to square one...

@guru: Even SRS was unable to recover F3 with lost rom, do you think they couldn't ask nice enough?
However, head adaptives are not hard to recover, media adaptives are the though part...

Do I take it from the post above that there are head adaptives (probably in relation to optimal write current and read biasing etc?) as well as media adaptives

So, you want to say, that lost original pcb for WD or Hitachi ARM is not a problem/not Actually? :)

Lost original PCB for WD is NEVER a problem.
