Sorry, it doesn't help me. :-(
Your model does have some firmware problems, but they don't appear to apply in your case:https://ata.wiki.kernel.org/index.php/Known_issues
The fact that your drive spins up would suggest that the board is most probably OK. Instead the fault is most likely an internal one.
BTW, some Seagate models, eg 7200.11, have a BSY bug that manifests itself in the way that you have described. That's why model numbers are important.
