As an aside, is your drive still spinning? Does it click, and /or spin down?

Competent recovery work entails: 1) accurate diagnosis; 2) proper tools and techniques; 3) be efficient and concise, i.e. don't perform unnecessary steps, and minimize risk.
So let's look at what you've done:
1. You performed a platter instead of head swap (while it may be done that way, you've introduced a new possibility that the platter operation will be less than optimal) -- this runs contrary to #3.
2. You assumed that close dates would suffice for heads match. With Seagate, you usually must inspect sliders. See #2.
3. You operated outside of a clean room (a bad idea) -- contrary to #2 and added to risk (#3). We don't know if your head loading and unloading techniques are up to snuff.
4. When the drive failed to work with the donor parts, you didn't inspect the donor heads for damage. Nor did you put them back into the donor to see if they worked. (#1 & #2)
5. Comparing ROM codes was perhaps academic, but not very helpful (#3)
6. Migrating ROM adaptives probably wasn't necessary (although it could have been). The ROM checksum got corrupted in the process. (#1 & #3). Some may do it as a matter of course; I do it when something doesn't work well and I have ruled out other causes.
7. You have no idea what the Seagate terminal log entries mean (they are admittedly cryptic), and you haven't posted all of the log messages to the forum. You probably have firmware issues and well as physical / mechanical problems.
Shall I stop there?
I appreciate this information, it appears i assumed and made a difficult situation worse. Now i will know for the future.
That being said, on the topic of providing terminal output, i could very easily have provided pages of output, but i must admit i did not care for the condescending responses that were given to my questions, and at that point kind of gave up hope of getting any reasonable level of help from this forum.
I understand you fine folks are offering information, for free, and on your own time, but you may consider being a little more human about it. I feel i was as polite and as outwardly ignorant as possible when asking for assistance, and with the exception of the underlying information in your post i got nothing condescension and ridicule.
I guess all i'm saying, is, is that really necessary, and is that how you would like your legitimate attempts at information gathering treated.
