is it possible restore data from the hdd with removed rom ic?

[harp]

is it possible restore data from the hdd with removed rom ic so, is there any way, theory or practice, to restore or calculate missing data in flashrom ic from actual data stored on disk platers? In other words, is data on disc somehow reachable, recover without original rom firmware, using exactly donor board, special lab hardware, etc?

Yes, indeed, thank you!

The only successful thing I have done in the past for drive that is not recognize by the motherboard is is to find another drive that has a board that is recognized by the motherboard and see if it can be read by it successfully about 40% of time has been my experience

But the model numbers have to match the size of the drive has to match and the boards must match the closer you match the production date the better

If you have a specific HDD model in mind, then an answer can be better targeted. The question, as it stands, is unanswerable. I suggest that HDD Guru or HDD Oracle would be more appropriate places to research this subject. Depending on your location on Planet Earth, Ru.Board may be another option.

Nothing specific... I just wonder if the present of rom ic has any impact on data safety, if is desired to save all other hardware resource of hdd.......... we can see that method removing or wipeing rom ic it not safe, beside some claims that rom ic hold "esenciall and unique" data required to function...

My understanding is that most Seagate HDDs since 7200.11 cannot be recovered if the ROM is missing. Also, no (?) Toshiba HDD is recoverable without the original ROM.The current firmware architectures have additional complications related to security.
